Description

SHOE WITH VENTILATION IN THE LOWER SHAFT AREA AND AIR-TRANSLUCENT ABSTRATE OF USE THEREOF

The invention relates to shoes with ventilation below the sole of the foot and with the removal of sweat moisture through layers below the foot to improve the climate comfort of such shoes.

In former times, shoes in the sole area either had some water vapor permeability, also called breathability, due to the use of outsole material such as leather, with the disadvantage of water permeability in the sole area, or shoes in the sole area due to the use of outsoles of waterproof material such as rubber or rubber-like plastic, waterproof but also impermeable to water vapor, with the disadvantage of the accumulation of moisture in the sole of the foot.

Recently, shoes have been made which are both waterproof and permeable to water vapor in the sole area by perforating their outsoles with through openings and covering the through openings by means of a waterproof, water vapor permeable membrane arranged on the inside of the outsole, so that no water from the outside can penetrate into the shoe interior, but sweat moisture arising in the area of the sole of the foot can escape from the inside of the shoe to the outside. Here are two different solutions gone. Either you have provided the outsole with their vertical thickness through openings through which sweat moisture from the shoe interior to the tread of the outsole can be passed, or you have provided the outsole with horizontal channels over which sweat moisture that has collected above the outsole over the lateral extent of the outsole can escape.

Examples of the first approach, in which the outsole has vertical through holes penetrating its thickness, are shown in EP 0 382 904 A1, EP 0 275 644 A1 and DE 20 2007 000 667 UM. A sole composite according to EP 0 382 904 A1 has a bottom sole part provided with microperforations, an upper sole part likewise provided with perforations and, in between, a watertight, water vapor permeable membrane. In the case of shoes according to EP 0 275 644 A1, the outsole is provided with relatively large vertical through-openings in order to obtain greater water vapor permeability and is used for mechanical protection of the membrane between it and the running surface. sole arranged a water vapor permeable protective layer. In shoes according to DE 20 2007 000 667 UM, the outsole is provided with relatively large vertical through-openings to obtain a stronger water vapor permeability, which are closed by a protective layer permeable to water vapor. Such an outsole is attached to a watertight shaft assembly, thus providing a watertight shoe.

Examples of the second approach in which the outsole has horizontal venting channels running parallel to its tread are known from EP 0 479 183 B1, EP 1 089 642 B1, EP 1 033 924 Bl and JP 16-75205 U.

In the case of a shoe according to EP 0 479 183 B 1, the outsole is provided on its outer periphery with a raised outsole edge on its outer side facing away from the running surface, which is penetrated by horizontal, that is, parallel to the running surface microperforations. In the space formed within the outsole edge, a stand-off element is arranged with transverse webs standing up from the outsole, which can be formed in one piece with the outsole. Within the outsole edge and at a distance therefrom is an inner band associated with the spacer which is also penetrated by horizontally extending passage openings. Above the spacer there is a water-vapor-permeable mounting shoe or insole, under the outer peripheral region of which a lasting impact of a shaft made of water-vapor permeable material is beaten, which is located on the inner side of the inner band of the spacer element. Between the outsole edge with the horizontal microperforations and the inner band with the horizontal passage openings is a waterproof, water vapor permeable membrane which extends approximately perpendicularly from the inside of the outsole. As a result of this

On the one hand, water is prevented from penetrating between the webs and further into the shoe interior, but on the other hand sweat moisture, which has passed from the shoe interior space between the webs, can theoretically reach the outside of the sole structure. However, the sweat moisture must penetrate not only the membrane but also the microperforations of the outsole edge, the passage openings of the inner band and the shaft material.

In the case of EP 1 089 642 B1, the outsole is provided on its side facing away from the tread on the outer circumference with a raised edge web, in the top of the edge web permeating vent channels are inserted, and provided in a sole region within the edge web with hemispherical projections. On the upper side of the outsole, an upper sole element is arranged, which rests on the edge web and on the projections of the outsole and has a water-vapor-permeable region covered with a watertight, water-vapor-permeable membrane with a ner extent approximately equal to that provided with the projections portion of the outsole. Sweat moisture, which accumulates in the space between the outsole and sole element, in which the projections of the outsole are located, can theoretically escape via the ventilation channels in the edge web of the outsole.

EP 1 033 924 B1 shows a shoe with an outsole with an outer circumferential edge standing up from an inner side of the outsole, which is penetrated by horizontal ventilation channels, ie running parallel to the running surface of the outsole. The outsole is attached to a shaft having a bottom side lower shaft portion having a lasting impact associated with the underside of a peripheral portion of a perforated mounting sole. In the space formed within the Zwickinschlags a waterproof, water vapor permeable membrane is disposed on the underside of the mounting base. In the outsole space formed within the high-standing outer peripheral edge there is an air-permeable material constructed with fibers, for example made of felt. Sweat moisture, which has passed through the perforated mounting base and the membrane into the air-permeable material, can diffuse through the horizontal ventilation channels of the outer peripheral edge of the outsole in the outside environment. However, water which has passed through the ventilation channels in the air-permeable material is prevented by the membrane from passing through the mounting sole into the shoe interior. On the inside of the outsole is a nail protection plate, so that this shoe is suitable as a safety shoe.

From JP 16-75205 U a shoe is known in which the two above-mentioned approaches are combined. The sole construction of this shoe has a perforated mounting sole, an outsole provided on its upper side facing the shoe interior with horizontally extending horizontal grooves opening to the outside of the outsole periphery and through-holes extending from these grooves to the tread, and has one on the underside of the mounting sole arranged waterproof, water vapor permeable membrane and a arranged between the membrane and the sole sole protective layer, for example made of felt. A sole-side lower end region of a shaft is embossed in the form of a lasting impact on the underside of a circumferential edge region of the mounting sole. While the membrane has the same extension as the mounting sole, the protective layer is located in the same plane as the lasting edge and the protective layer extends only between the inner edge of the gusset. The horizontally extending grooves are open at the periphery of the outsole to the outside environment. Thus, perspiration moisture can diffuse out of the shoe interior through both the vertical through holes to the outside of the tread of the outsole and the horizontal grooves to the outer peripheral side. In particular, in the case of shoes whose outsole is not provided with vertical passage openings penetrating through their thickness or which can not be provided for safety reasons, for example because of the need for a nail protection plate, but even for shoes whose outsole is provided with such vertical passage openings, it is desirable to create a venting system in an area below the sole of the foot, with which a noticeable increase in climate comfort in the area of the sole of the foot can be achieved.

From these points of view, a shoe has been created by means of the invention disclosed in the German patent application DE 10 2008 027 856 of the Applicant, which has a ventilation space defined by an air-permeable spacer structure below the sole of the foot, which efficiently removes condensation moisture (water vapor) passing through the Layers under the foot has reached allows.

This shoe has a shaft arrangement and a sole, wherein the shaft arrangement has a shaft upper material and an air-permeable layer arranged in a shaft bottom. The air-permeable layer is arranged in a sole-side lower region of the shaft arrangement above the sole. The air-permeable layer has a three-dimensional structure permitting air passage in at least the horizontal direction. The upper upper material has at least one air passage opening in a sole-side lower peripheral region, by means of which a connection can be established between the air-permeable layer and the outer environment of the shoe such that an exchange of air between the outer environment and the air-permeable layer can take place. In this way, heat and water vapor can be dissipated from the region of the shaft arrangement located above the air-permeable layer, for example by means of convective air exchange through the air-permeable layer.

In this solution, since the at least one air passage opening, which in conjunction with the air-permeable layer allows the efficient removal of sweat moisture, is not formed in the outsole, where it is not from the standpoint of outsole stability and especially in a shoe with a rather thin outsole for aesthetic reasons can be particularly large, but in a sole-side lower peripheral region of the upper shaft material, where you can easily make the air passage opening comparatively large, one achieves thereby already a better air exchange and thus higher Wasserdampfabführmöglichkeit than a shoe whose at least one air passage opening is formed in the outsole.

Such a shaft arrangement with the air-permeable layer also has the further advantage that the air-permeable layer, which between the at least one air passage Lassöffnung and the shoe interior is positioned to extend directly to the inside of the shaft upper material and not, as in the known solutions according to EP 1 033 924 Bl and JP 16-75205 U is limited to the interior space between the Zwickinschlagsrand the upper shaft material. For example, in the case of gusseted shoes, the air-permeable layer is above the bonded sockstring and can therefore provide a greater exchange surface for water vapor and heat of the sole of the foot. Therefore, in this solution, the air-permeable layer can have a significantly larger surface area than in the known solutions, with a correspondingly larger exchange area and thus Wasserdampfabführkapazität.

The high Wasserdurchampfdurchlass- and Luftaustauschwirkung achieved with this solution is advantageous both for shoes that do not have to be waterproof because they are used only in dry areas, such as work shoes in an assembly hall, as well as shoes that are worn outdoors and therefore may be exposed to moisture.

For the latter case, an embodiment of this solution is used in which an at least water-vapor-permeable functional layer is provided at least in a lower region of the shaft arrangement facing the sole, the air-permeable layer being arranged below the functional layer. In one embodiment of this solution, the air-permeable layer is located directly below the water-vapor-permeable functional layer. In one embodiment of this solution, the functional layer is waterproof and permeable to water vapor.

In one embodiment of this solution, both a shank functional layer and a shank bottom functional layer are provided so that water vapor permeability is achieved with simultaneous waterproofness for both the shank and the shank bottom region of the shoe.

In a further embodiment of this solution is located in the shaft bottom region, a waterproof and water vapor permeable functional layer, for example in the form of a functional layer laminate, wherein the air-permeable layer is located directly below the functional layer or the functional layer laminate. In connection with this embodiment, an advantage of this solution lies in the fact that an air exchange and thus a removal of sweat moisture and heat is made possible by the at least one air passage opening in cooperation with the air-permeable layer. The diffusion-limiting diffusion path, which the water vapor first has to cover from the underside of the foot to the air-permeable layer, is determined by the choice of a thin layer of layers enclosing the functional layer. minimized between foot and air permeable layer, maximizing heat transfer. When the steam has reached the air permeable layer, it is additionally carried away convectively via the air flow, whereby the water vapor partial pressure difference between the two sides of the functional layer is permanently maintained at a high level. There are no more layers to overcome. The water vapor partial pressure difference between the two sides of the functional layer is a driving force for the efficient removal of perspiration moisture. In addition to the steam, heat is also dissipated by the convection. The fact that, in the case of a spliced shaft, the air-permeable layer is arranged above the lasting end of the shaft upper material, approximately the entire sole surface is available for the water vapor exchange.

In one embodiment of this solution with shaft functional layer and shaft bottom functional layer, these are part of a sock-like functional layer bootie, in which a shaft region is formed by the shaft functional layer and a sole region by the shaft bottom functional layer.

In another embodiment of this solution with the shank functional layer and the shank bottom functional layer, the shank functional layer and the shank bottom functional layer in the lower shank region are connected to one another and watertight sealed against each other at their common boundary.

In one embodiment of this solution, the functional layer of the shaft functional layer and / or the shaft bottom functional layer is part of a multilayer laminate, which has at least one textile layer in addition to the functional layer. Frequently used laminates are two-, three- or four-day formed with a textile layer on one side or a respective textile layer on both sides of the functional layer.

In one embodiment of this solution, a shaft bottom functional layer laminate and / or a shaft functional layer laminate are constructed with the laminate.

In one embodiment of this solution, the functional layer has a water vapor permeable membrane. Preferably, the membrane is waterproof and permeable to water vapor. In a preferred embodiment, the functional layer has a membrane constructed with expanded microporous polytetrafluoroethylene (ePTFE).

In one embodiment of this solution, the air-permeable layer is located below the shaft bottom functional layer. In one embodiment of this solution, the air-permeable layer is located immediately below the shaft bottom functional layer, which should in the case that the shaft bottom functional layer is part of a functional layer laminate, that the air-permeable layer is located immediately below the functional layer laminate.

In one embodiment of this solution, at least one air passage opening in the upper shaft material is arranged so that it is at least partially at the same height as the air-permeable layer.

In one embodiment of this solution at least two in the foot transverse direction or in the foot longitudinal direction at least approximately opposite air passage openings are arranged in the lower region of the upper upper material. Thus, the convective air exchange is also enabled or promoted. The air exchange is strongly promoted by the relative movement of the shoe wearer to the outside air. Wind and / or walking or running increases the air exchange.

In a further embodiment of this solution, the lower peripheral portion of the upper shaft material has a plurality of air passage openings arranged along the circumference of the shaft assembly.

In one embodiment of this solution, the lower end of the upper of the upper has a separate air permeable upper material which is attached to the upper of the upper and thus forms part of the upper of the upper. This air-permeable shaft material, which extends around most of the shaft circumference or even around the entire circumference of the shaft, has a plurality of air passage openings due to the air-permeable structure. In one embodiment, the air-permeable shaft material is attached in the form of a mesh to the lower end of the upper upper material. In other embodiments, the air-permeable shaft material may be constructed of a perforated or latticed material. This air-permeable shaft material can be made stable in such a way that it gives the shaft the required shape stability despite these air passage openings extending almost or completely around the entire shaft circumference.

In one embodiment of this solution, the at least one air passage opening has a total area of at least 50 mm ² , preferably of at least 100 mm ² .

In a further embodiment of this solution, the at least one air passage opening is covered with an air-permeable protective material, for example a protective net or protective grille made of metal or plastic, for the penetration of foreign bodies such as impeding dirt or pebbles through the air passage opening. The air-permeable protective material may be located in the region of the lower peripheral region of the upper material of the shaft along the air-permeable layer, either on the outside of the air passage opening or on the inside of the air passage opening between the upper upper material and the air-permeable layer.

In one embodiment of this solution, the at least one air passage opening can be closed by means of a device. The device serves for temporary protection against external elements, at least against splash water, so that water can not penetrate directly through the air passage opening. The device can be designed in the form of a movable device, for example as a slide, by means of which the at least one air passage opening can be partially or completely closed in order to throttle or prevent the exchange of air between the outside world of the shoe and the air-permeable layer. This may be advantageous, especially at low temperatures (such as in winter), because too strong a cooling effect can occur through the removal of sweat moisture and the associated cooling effect in connection with the exchange of air through the air-permeable layer. By closing the air passage openings by means of the movable device, an excessive ingress of water when walking in a very wet environment can be counteracted.

In one embodiment of this solution, for example, a fan or blower installed in the air-permeable layer ensures a constant exchange of air with the environment. The performance of the fan can regulate itself independently to maintain a desired setpoint temperature on the foot. The fan may be required for a noticeable cooling effect, especially in the case of small or low reef motions between the shoe and ambient air, as well as at high ambient temperatures.

In one embodiment of this solution, which is a nipped shoe in which a sole side stuffer of the upper of the upper is adhered to a peripheral edge of the underside of a mounting sole or insole (also known as AGO), the stiffener and mounting sole are located with which the Zwickeinschlag is glued, below the air-permeable layer.

However, this solution is not limited to shoes with a fluted shank, but is applicable regardless of how the lower portion of the upper of the upper has been processed to obtain a shank-bottomed shaft arrangement. In addition to the Zwick-style also known per se other types are applicable. Examples include the Strobel-style, in which the lower portion of the upper shank material by means of a so-called Strobelnaht to the circumference of a Mon- sewn on the Einschließ-Machart (also known as "string-Lasting"), in which at the sole side end portion of the shaft upper a Schnettunnel, for example in the form of a spiral loop seam, is attached, through which a movable Einindeschnur leads, by means of which the sole side end portion of the upper shaft - materials can be contracted; and the moccasin-style, in which the shaft, with the exception of the blade, and the shaft bottom are made in one piece from a piece of shaft upper, usually leather.

In one embodiment of this solution, all the components of the shoe contributing to the breathability are located above a boundary plane between the upper and the sole. Thus, all components of the shoe, with the exception of the ground contacting outsole, are part of the shaft assembly. This shank arrangement can be completely completed before the outsole is attached to the shaft arrangement in a temporally and possibly spatially separate second production step for the completion of the shoe. The attachment of the outsole can immediately after the completion of the

Shaft assembly in a single pass of the shoe production happen, or with completion of the shaft assembly, a self-contained manufacturing step is first completed, after which the shaft assembly thus obtained is brought to another manufacturing site, where the shaft assembly is provided with the outsole. This manufacturing site may be located in the same factory where the stem assembly is made. The manufacturing site where the shaft assembly is provided with the outsole, but may also be located in a very different location than the manufacturing location for the shaft assembly, so that between the step of manufacturing the shaft assembly and the step of attaching the outsole to the Schaftanord- An interruption of the manufacturing process may take place during which the finished shaft assembly is brought to the manufacturing site for attaching the outsole to the shaft assembly. Since all the components of the shoe are accommodated in the shaft assembly, with the exception of the outsole, by attaching not only the shaft bottom functional layer but also the air-permeable layer to the shaft bottom or form part of the shaft bottom, before the outsole is attached to the shaft assembly, for example Sprinkling or gluing can be done, the one manufacturing site, which is responsible for attaching the outsole to the shaft assembly, nothing more than to install this outsole, for which normal conventional methods and tools sufficient. The more difficult and delicate part of the shoe production, namely the handling and assembly of the functional layer and the air-permeable layer, is involved in the production of the shaft assembly, ie in a manufacturing phase, in which anyway more complicated and complex process steps are required than in a method step in which only an outsole is attached to the shaft assembly.

In one embodiment of this solution, the sole is additionally provided with at least one sole passage opening extending through its thickness. This embodiment leads to a shoe in whose sole region a removal of sweat moisture and heat both in the vertical direction over the at least one sole passage opening and in the horizontal direction over the at least one air passage opening of the upper upper material is made possible. In addition, the at least one sole passage opening serves as an aid to improved drainage of water, which has reached an area above the outsole.

In one embodiment of this solution, a penetration protection element, for example in the form of a nail protection plate, is arranged in or above the outsole for producing a safety shoe. This prevents that objects lying on the floor, such as in particular nails, which can be entered into the outsole, penetrate into the shoe interior through these and overlying further elements of the sole structure and the shaft bottom and can injure the foot of the user of the shoe , Such objects as nails are intercepted by the penetration protection element, which is, for example, a steel plate or a plastic plate with a corresponding penetration resistance. Since in such a safety shoe, the outsole passing through openings make no sense, because these are covered by the nail protection plate anyway, remains in such a shoe for ventilation in the plantar area and thus improve the climate comfort exclusively the horizontal lateral removal of sweat moisture.

In one embodiment of this solution, the air-permeable layer is formed as an air-permeable spacer structure, which is designed so that the air-permeable layer, even under load by the foot of the user of the shoe maintains such a distance between the under and over their layers that the air permeability of the permeable layer is maintained.

In one embodiment of this solution, the air-permeable spacer structure is at least partially elastically yielding. As a result, the walking comfort of the shoe is increased because with this type of air-permeable spacer structure a shock absorption and a lighter rolling when walking is achieved.

In one embodiment of this solution, the air-permeable spacer structure is designed such that it is elastic at maximum load with the maximum expected weight of the shoe user corresponding to the shoe size of the respective shoe insofar gives way that even with such a maximum load still a significant portion of the air conductivity of the air-permeable layer forming spacer structure is maintained. With this proviso for the air-permeable spacer structure is ensured that the air-permeable spacer structure is not completely compressed under load by the user of the shoe with loss of its air permeability, but that it is the distance function and thus the air permeability of the spacer structure even under load from the user of the shoe to a sufficient degree for the ventilation function.

In one embodiment of this solution, the air-permeable spacer structure has a first support surface forming sheet and a plurality of perpendicularly and / or at an angle between 0 ° and 90 ° away from the sheet extending spacers. In this case, the ends of the spacer elements which are remote from the fabric define together a surface by means of which a second bearing surface remote from the fabric can be formed.

In one embodiment of this solution, the spacer elements of the spacer structure are formed as nubs, wherein the free knob ends taken together form said second bearing surface.

In one embodiment of this solution, the spacer structure on two mutually parallel sheets, wherein the two sheets are connected by air permeable means of the spacer elements together and kept at a distance. Each of the fabrics forms one of the two bearing surfaces of the spacer structure.

Not all spacer elements must have the same length in order to make the two support surfaces equidistant over the entire areal extent of the spacer structure. For special applications, it may be advantageous to make the distance structure in different zones or at different locations along its areal different thickness borrowed, for example, to form a Fußgerechtes footbed.

The spacer elements may be formed separately, that is, they are not connected to each other between the two bearing surfaces. However, it is also possible to allow the spacer elements to contact each other between the two bearing surfaces or to fix at least a portion of the contact points formed thereby, for example by adhesive or by the spacer elements being made of a material that can be welded together, such as a Heating adhesive capable material exist. The spacer elements may be rod-shaped or thread-like individual elements or sections of a more complex structure, for example a truss or latticework. The spacer elements can also be connected to one another in a zigzag shape or in the form of a cross lattice.

By selecting the material of the spacer elements and / or by selecting the angle of inclination of the spacer elements and / or by selecting the proportion of the contact points to which adjacent spacer elements are fixed together and / or the shape of the tray or lattice used, the stiffness and thus dimensional stability Adjust the spacing structure under load to the respective requirements.

In one embodiment of this solution, the distance structure is wave-shaped or sawtooth-shaped. In this case, the two bearing surfaces are defined by the upper and lower peaks or the upper and lower sawtooth apex of the spacer.

In one embodiment of this solution, the spacer structure is constructed with a consolidated knit, wherein the solidification for example by gluing, for which a synthetic resin adhesive can be used, or by thermal action, by constructing the spacer with thermoplastic material and this for solidification to a softening temperature which this material glued together, is heated.

In one embodiment of this solution, the spacer structure is constructed with a material which is selected from the material group polyolefins, polyamides or polyesters.

In one embodiment of this solution, the spacer structure is constructed with fibers, at least part of which is arranged as a spacer perpendicularly between the fabrics.

In one embodiment of this solution, the fibers are constructed with a flexible, deformable material.

In one embodiment of this solution, the fibers consist of polyolefins, polyester or polyamide.

In one embodiment of this solution, the sheets are constructed with open-pored woven, knitted or knitted textile materials. In one embodiment of this solution, the air-permeable spacer structure is formed by two air-permeable fabrics arranged parallel to one another, which are interconnected in an air-permeable manner by means of mono- or multi-filaments and at the same time are spaced apart.

In one embodiment of this solution, the fabrics are constructed with a material selected from the group of materials of polyolefins, polyamides or polyesters.

In one embodiment of this solution, at least a portion of the mono- or multifilaments of the spacer structure are arranged as spacers approximately perpendicularly between the fabrics.

In one embodiment of this solution, the mono- or multi-leg assemblies consist of polyolefins and / or polyesters and / or polyamides.

In this solution, the air-permeable layer or the air-permeable spacer structure forming it has the function of a ventilation sizing whose ventilation effect is based on a very low flow resistance for air. The air exchange causes an efficient removal of moisture in the form of water vapor from the shoe interior to the shoe outside.

A further advantage of this solution is that due to the arrangement of the air-permeable layer in the shaft bottom region of the shaft arrangement, conventional soles can be used without additional modifications. Especially in mountain shoes and trekking shoes, the border area between sole and shaft assembly is sealed from the outside along the shoe circumference with an additional rubber sole band. This band must also be perforated in the area of the air passage openings. Shell soles may be used for embodiments of this solution if, for example, the air passage openings in the shaft material are arranged above the shell edge or if the additional sole band at the locations where it lies above the at least one air passage opening of the upper shaft material, in turn with one or more corresponding Air outlet openings is provided.

The at least one air passage opening may have any shape. In one embodiment of this solution, the at least one air passage opening has a round shape, for example, is circular or elliptical. The shape of the at least one air passage opening can also be angular, for example, the shape of a square or an elongated rectangle.

In one embodiment of the solution according to DE 10 2008 027 856, instead of individual air passage openings, a strip of air-permeable material is formed, which extends around the entire circumference of the lower shaft upper region, thereby achieving a particularly high air exchange between the air-permeable layer and the outside environment of the shoe with correspondingly effective dissipation of heat and moisture from the shoe interior to the outside environment of the shoe. The air-permeable material forms a part of the upper shaft material. In one embodiment of this solution may be a separate perforated, latticed or reticulated material which is fixed in the sole side lower peripheral portion of the upper shaft material on this, or the upper shaft material itself is mechanically processed in this lower peripheral region, such as by punching or Perforate. The air-permeable material used may be meshes, meshes, latticed textiles, open-pore foams, air-permeable textiles and combinations of these materials. These materials may, for example, consist of polyester, polyamide, polyolefin, TPE (thermoplastic elastomers), TPU (thermoplastic polyurethane), vulcanizates.

Disposing a strip of air-permeable material over a portion of the air passage openings of the upper or over all air passage openings of the upper of the upper or replacing the upper of the upper at the level of the air-permeable layer to form a single circumferentially extending air passage is not easy to realize this strip of air-permeable material evenly along the air passage openings or evenly spaced from the upper edge of the sole. This can be particularly difficult when the shoe is one in which the sole-side lower end portion of the upper upper material is attached to a lower peripheral portion of a shaft bottom, for example, a mounting sole, by means of Zwickklebung due to the high Zwickkräfte, which the Zwickklebung must be applied. Even with shoes in which the sole-side lower end region of the upper upper material is fastened to a lower peripheral region of a mounting sole by means of a seam, high tensile forces occur

Such problems are overcome by inventively designed footwear according to claim 1. Embodiments of the footwear designed according to the invention are claimed in the dependent claims. Footwear according to an embodiment of the invention has a shank arrangement and a sole, wherein the shank arrangement has a shank upper material and an air-permeable layer arranged in a shank bottom. The air-permeable layer is arranged in a sole-side lower region of the shaft arrangement above the sole. The air-permeable layer has a three-dimensional structure permitting air passage in at least the horizontal direction. A sole-side lower peripheral region of the upper upper material is replaced over at least a part of its circumferential extent by at least one connecting material, which is at least above a bottom of the air-permeable layer starting and outside the air-permeable layer extending and attached to the shaft bottom and at least in a partial area, at least is partially at the same height as the air-permeable layer, is permeable to air and thereby the air-permeable layer with the outside environment in combination so that air between the outside environment and the air-permeable layer can be replaced.

By the measure according to the invention, at least a part of the actual upper upper material above or at the level of the air-permeable layer to stop and replace up to the sole side lower end of the shaft structure by means of the connecting material, which at least in the area which Hegt at the height of the air-permeable layer, permeable to air is achieved with relatively little effort, the ability to create a shaft structure, which ensures a secure air-permeable cover the air-permeable layer with a neat appearance.

In one embodiment, the attachment of the connecting material to the shaft bottom is effected by means of adhesive bonding on the underside of a shaft bottom layer, in which e.g. around the air-permeable layer or a mounting sole can act. In this case, the lower end of the connecting material forms the lasting impact.

In the event that there is a shaft lining on the inside of the upper upper material, this can also be attached by Zwickmontage, in particular Zwickklebung, or in any other way, for example by being stripped, that is attached by means of a Strobelnaht on a Schaftfuttermontagesohle.

The air-permeable connecting material has two essential functions. First, it ensures that air can be exchanged between the air-permeable layer and the outside environment. On the other hand, the connecting material is used for fastening the upper upper material on the shaft bottom, for example on a mounting sole or on the air-permeable layer. This fastening process comprises all known methods ren for producing a shaft assembly, such as pinching, stroking or string-loading.

The connecting material may be strip-shaped, in particular in the form of an extension strip.

The connecting material may be permeable to air over its entire width or only over part of its width, which is located after the fastening operation at the height of the air-permeable layer.

The connecting material can run around the entire lower peripheral region of the upper material of the shaft.

In particular, reticulated or grid-like materials are suitable as material for the connecting material. Preferably, the connecting material is through a grid belt or a

Net band formed. This can have approximately equal openings over its entire width. In one embodiment, the grating or net strip may be provided with larger openings in that region, which is assigned to the air-permeable layer, in order to obtain the greatest possible air permeability than, in particular, in the fastening region, for example in the intermesh region of the connecting material. In this way, where particularly high forces occur, namely in the attachment area, a higher strength and load capacity ensured than in the air-permeable layer opposite portion of the connecting material is required. Since the bonding material must absorb the main load during the fastening process and during the application, one should select a correspondingly stable material for the bonding material, while gaining greater freedom in terms of material selection for the actual upper shell material, which is freed from the main load by the bonding material Has.

In general, the bonding material should be characterized by a high abrasion resistance, high puncture resistance (against stones, branches, etc.), adhesiveness and sewability. It is also advantageous if the bonding material does not fray at the cut surfaces. When selecting the material for the connection material mechanical protection, dirt and water repellent properties, as well as optics play an important role.

As the air-permeable bonding material, nets, meshes, latticed fabrics, open-cell foams, air-permeable fabrics, three-dimensional knitted fabrics, knitted fabrics, woven fabrics, knits, air-permeable fabrics, inorganic fiber materials such as glass fibers or carbon fibers, and combinations of these materials may be used. The connecting material can in principle consist of all engineering thermoplastics, thermosets and elastomers. Also special metals or combinations of plastic and metal, metallized polymers or metal knits are suitable. Examples of plastics are PUR (polyurethane), polyester, polypropylene, polyamide, polyolefins, TPE (thermoplastic elastomers), TPU (thermoplastic polyurethane), EPDM (ethylene-propylene-diene rubber), SAN (styrene-acrylonitrile copolymers), SBR (Styrene-butadiene rubber), ABS (acrylonitrile-butadiene-styrene), vulcanizates, silicones, and combinations of these materials. Also rubber can be used for the connection material. The bonding material may also comprise at least one air-permeable membrane or an air-permeable film.

For example, the connecting material may also have at least two different material areas.

The bonding material may comprise one or more components.

In one embodiment, the bonding material comprises a plurality of components, for example in the form of a composite material. In one embodiment, the composite is formed with a coated or impregnated mesh tape or mesh, such as a rubberized fabric. A coating / impregnation can also be based on acrylates, silicones or polyurethanes. In general, it is advantageous if the air-permeable bonding material is hydrophobic.

In a further embodiment, the coating of the air-permeable connecting material simultaneously serves as an adhesive for fastening further materials or for attachment to other materials. For example, by means of the coating, a cover strip provided with air-permeable openings which covers at least parts of the connecting material can be fastened to the connecting material without additional adhesive. In another example, the coating serves as a Zwickklebstoff. In one embodiment, a mesh belt or net (lattice-shaped textile) is coated with polyurethane, which acts as an adhesive when heated. It must be ensured that sufficient adhesive is applied to the mesh or net tape for an adhesive bond.

It is also possible to use prefabricated composite materials, such as a rubber band provided with air-permeable openings, which has been reinforced / solidified with fibers or a textile structure (mesh or grid). In the openings of the rubber band is only the net or grid. A prefabricated connection material may also be connected to a further component, for example it may be one with a Include rubber band glued grid tape. In these cases, the rubber band takes over the function of the above-mentioned cover strip, which will be explained in more detail below. Thus, it is possible to integrate a separate cover strip in the connecting material. This saves additional work steps and simplifies the manufacture of the shank arrangement.

Furthermore, the bonding material can have different material properties and / or physical properties over its width. For example, the bonding material has a particularly high air permeability in the region of the air-permeable layer, but low air permeability in the lower fastening region. Other different properties could be ductility, strength and / or thickness. For example, in one embodiment, the connecting material in the lower region, which serves for attachment to the shaft bottom, formed thinner. This ensures that with the attachment of the connecting material on the shaft bottom, the air-permeable openings do not slip or deform and are permanently at the same height as the air-permeable layer.

The connection between the lower end region of the actual upper upper material and the upper end region of the connecting material can be produced for example by means of gluing, welding or sewing.

In one embodiment of the invention, on the outside of the shank, starting from at least part of the upper peripheral edge of the sole, there is a covering strip, which extends beyond an upper end of the connecting material as far as the

Shaft upper extends and is permeable to air in at least a portion of that which covers such parts of the connecting material, which are at least partially at the level of the air-permeable layer.

Such a cover strip is, in particular, a protective tape which, in particular in so-called trekking shoes, is conventionally attached peripherally around the circumference of the lower end of the shaft in order to provide protection for this shaft region, which is exposed to particularly high levels of abrasion stress. Such a cover strip is often made of rubber or rubber-like plastic, which is why the term is often used for such a cover strip

"Rubber band" is used. Nevertheless, this cover strip does not have to be a real rubber band, but it can also be used, for example, a reinforced textile material that is inherently abrasion-resistant or provided with an abrasion-resistant finish. Thus, in the area of the air-permeable layer, the air permeability to the outside environment is not affected, and the cover strip is at least in that area which is located at the height of the air-permeable layer, permeable to air. In particular, if the material of the cover strip is rubber or rubber-like plastic, the cover strip is rendered permeable to this air permeability at least in the region in which it faces the air-permeable layer and must therefore be air-permeable.

The cover strip is located on the outside of the connecting material and extends advantageously over that area where the connection between the actual upper upper material and the connecting material is located. In this way, this connection area is hidden and not visible to the outside, which is useful for a good appearance of the footwear.

The cover strip may also be connected to the bottom of the shaft at its bottom side, for example by means of a Zwickvorgangs be attached to this. This can be done by tweaking it by gluing it to the underside of the connecting material, for example, being wound onto the air-permeable layer, and gluing it tightly there. This has the advantage that the Zwickkräfte need not be absorbed by the connection material alone but distribute to the connecting material and the cover strip. In a further embodiment, the cover strip is connected to the connecting material such as glued, welded or sewn and then both are fastened together by means of a Zwickvorganges on the shaft bottom.

Shoe or footwear:

Footwear with a closed upper part (shaft arrangement), which has a Fußein- schlüpföffnung, and at least one sole or a composite sole.

Shaft assembly: completely encloses the foot up to a Fußeinschlüpföffnung and has in addition to the shaft and a shaft bottom. The shaft arrangement can furthermore have one or more linings, for example in the form of a liner and / or a watertight, water vapor-permeable functional layer and / or one or more insulating layers.

Shaft upper: a material which forms the outside of the shaft and thus of the shaft assembly and which consists, for example, of or is constructed of leather, a textile, plastic or other known materials and combinations thereof. In general, these materials and combinations are permeable to water vapor. The sole-side lower circumferential region of the upper upper material describes a region adjacent to the upper edge of the sole or above a boundary plane between the upper and the sole.

Shaft bottom: a sole side lower portion of the shaft assembly in which the shaft assembly is completely or at least partially closed. The shaft bottom is located between the sole of the foot and the outsole. For shoes with a twilled or striated shaft, the shaft bottom can be formed with the assistance of a mounting sole (insole). The bottom of the shaft can also be provided with a shaft bottom functional layer or a shaft bottom functional layer laminate, whereby this laminate can also assume the function of the mounting sole. In the case of footwear according to the invention, the shaft bottom also comprises the air-permeable layer.

Sole:

The term sole serves as a generic term for soles or sole layers of any kind.

Mounting sole (insole): a mounting sole is part of the shaft bottom, to which a sole side lower shaft end region is attached. The mounting sole may be provided exclusively for this purpose, in which case one speaks frequently of insole. As a mounting sole but can also serve a sole layer located in the shaft bottom, which is initially arranged there for a different purpose and is also used for the function of the mounting sole, for example, the existing in accordance with the invention footwear permeable to air. The mounting sole may be permeable to water vapor, for example, the mounting sole is formed of a material permeable to water vapor or is made permeable to water vapor by means of openings (holes, perforations) which are formed by the thickness of the mounting sole. In this case, the mounting insole for example, a water vapor permeability number Ret of less than 150m ² xPaxW ^''. The water vapor permeability is tested according to the Hohenstein skin model. This test method is described in DIN EN 31092 (02/94) and ISO 11092 (1993 ).

Sole:

A shoe has at least one outsole, but may also have several types of soles arranged one above the other.

Outsole: Outsole means the part of the sole area that touches the ground / ground or makes the main contact with the ground / ground. The outsole has at least one tread contacting the ground.

Midsole: In case the outsole is not attached directly to the shaft assembly, a midsole may be inserted between the outsole and the shaft assembly. The midsole can for example be the upholstery, cushioning or filling material.

Bootie:

Bootie is a sock-like inner lining of a shaft arrangement. A bootie forms a baggy lining of the shaft assembly which substantially completely covers the interior of the footwear.

Functional layer:

Water vapor permeable and / or waterproof layer, for example in the form of a membrane or a correspondingly treated or finished material, for example a textile with plasma treatment. The functional layer can form at least one layer of a shaft bottom of the shaft arrangement in the form of a shaft bottom functional layer but also in addition to be provided as a shaft at least partially lining shaft function layer; in the presence of both a shank functional layer and a shank bottom functional layer, these parts may be a multilayer, usually two-, three- or four-ply laminate; If, instead of a functional layer bootie, a shank functional layer and a separate shaft bottom functional layer are used, they are sealed against each other in a watertight manner, for example, in the sole-side lower region of the shank arrangement; Shank bottom functional layer and shank functional layer may also be formed of a material. Suitable materials for the waterproof, water-vapor-permeable functional layer are, in particular, polyurethane, polyolefins and polyesters, including polyether esters and their laminates, as described in the printed publications US Pat. No. 4,725,418 and US Pat. No. 4,493,870. In one embodiment, the functional layer is constructed with microporous, stretched polytetrafluoroethylene (ePTFE), as described, for example, in the publications US Pat. No. 3,953,566 and US Pat. No. 4,187,390, and oriented polytetrafluoroethylene, which is impregnated with hydrophilic impregnating agents and / or or hydrophilic layers; See, for example, US-A-4,194,041. A microporous functional layer is understood to mean a functional layer whose average effective pore size is between 0.1 .mu.m and preferably between 0.2 .mu.m and 0.3 .mu.m.

laminate:

Laminate is a composite consisting of several layers which are permanently bonded together, generally by mutual bonding or welding. In a functional layer laminate, a waterproof and / or water vapor permeable functional layer is provided with at least one textile layer. The at least one textile layer serves primarily to protect the functional layer during its processing. This is called a 2-layer laminate. A 3-layer laminate consists of a waterproof, water vapor-permeable functional layer, which is embedded in two textile layers. The connection between the functional layer and the at least one textile layer takes place, for example, by means of a discontinuous adhesive layer or a continuous water-vapor-permeable adhesive layer. In one embodiment, an adhesive may be applied in a punctiform manner between the functional layer and the one or both textile layers. The punctiform or discontinuous application of the adhesive takes place because a full-surface layer of a self-water vapor-permeable adhesive would block the water vapor permeability of the functional layer.

Waterproof:

A functional layer / a functional layer laminate is considered to be "waterproof", if appropriate provided on the functional layer / the functional layer laminate. These seams, if they / it ensures a water inlet pressure of at least 1x10 ⁴ Pa. Preferably, the functional layer material withstands a water entry pressure of about ⁵ Pa Ixio stand. The water inlet pressure shall be measured by a test method in which distilled water is applied at 20 ± 2 ° C to a sample of 100 cm ^{2 of} the functional layer with increasing pressure. The pressure increase of the water is 60 ± 3 cm water column per minute. The water inlet pressure then corresponds to the pressure at which water first appears on the other side of the sample. Details of the procedure are specified in the ISO standard 081 1 from the year 1981.

Whether a shoe is waterproof can e.g. are tested with a centrifuge arrangement of the type described in US-A-5,329,807.

Water vapor permeable:

As a "water vapor permeable" a functional layer / a functional layer laminate is considered if it has a water vapor transmission rate Ret of less than 150 m2><Pa ^χ Wl. The water vapor permeability is tested according to the Hohenstein skin model. This test method is described in DIN EN 31092 (02/94) or ISO 11092 (1993).

Breathable:

By "air-permeable" is meant in the present application the convective exchange of air and water vapor by means of air flow and the exchange of water vapor by means of pure diffusion processes or combinations thereof.

Air permeable situation:

The air-permeable layer has a three-dimensional structure permitting air passage in at least the horizontal direction. This structure has a low flow resistance for air. The air-permeable layer allows the absorption and removal of heat and water vapor from the shoe interior, for example by means of convection. The air-permeable layer contains an air volume of at least 50%, in an embodiment of more than 85%. The thickness of the air permeable layer may be less than 12mm, the thickness being less than 8mm in one embodiment. The air-permeable layer has a basis weight of less than 2000 g / m ² , preferably less than 800 g / m ² . The air-permeable layer covers at least 50% and preferably at least 70% of the foot contact surface of the shaft bottom. Furthermore, the air-permeable layer has a structure with such rigidity that it is at least not permanently compressed by the foot of the user while running substantially. As an air-permeable layer is suitable, for example, a distance structure, as it is known from DE 102 40 802 A2, but there in connection with an infrared-reflective material for clothing.

The air-permeable layer may be, for example, a molded structure of polymers, a 3D spacer or a textile structure solidified with polymer resins. The air pervious layer may also be made by an injection molding process, in one embodiment it may have a channel or tubular configuration, or be formed of polymer or metal foams.

Shaped structures of polymers are based on polymer monofilaments, fabrics, nonwovens or scrims which are formed by means of deformation and fixation of the materials to a ribbed, knobbed or zigzag structure. The structure may also be a 3-dimensional structure, for example of polypropylene, in the form of e.g. wavy or by other form brought to a 3D structure Filamentgeleges. The deformation and fixation can be carried out, for example, via a heated structural roller or as a thermoforming process. The shaped structures may additionally be laminated with a woven or non-woven fabric to improve dimensional stability. A possible method for producing such shaped structures is described, for example, in patent application WO 2006/056398 A1.

The air-permeable layer can also be formed from a 3D spacer structure. Such spacers are usually made of polyester multi- or monofilaments. Spacers may be spacer, spacer, spacer, or spacer. The active technology makes it possible to vary both the top and bottom of the fabric surfaces as well as the spacer thread (pile thread) independently of each other. Thus, the surfaces and the hardness including the spring characteristic can be adjusted depending on the type of individual application. Spacers are characterized by a very high air circulation in all directions, even under load. A spacer structure, for example in the form of a spacer knit, can also be produced via the impregnation of textile fabrics which are impregnated with synthetic resin before or after deformation into a 3-dimensional structure and thus obtain the desired rigidity.

As fiber material for the spacer structure also inorganic fibers such as glass fibers or carbon fibers can be selected.

Table 1: Selection of possible usable materials for the air-permeable layer

In summary, the air-permeable layer should maintain a distance between the foot and the outsole and form a plurality of passages, which oppose as little resistance as possible to an air flow and thus contribute to the transport of water vapor and heat without adsorbing the water vapor. The air permeable layer has no or at least substantially no capillary action. The air-permeable layer is closed at its bottom side by the mounting sole and / or a filling layer and / or the outsole and is open at least at its periphery in an air permeability permitting manner. Preferably, the air permeable sheet is additionally open on its upper surface also in an air permeability permitting manner. The upper surface of the air-permeable layer facing the shaft interior is in one embodiment directed towards a watertight and possibly also water-vapor-permeable functional layer. The air permeability of spacers is determined on the basis of DIN EN ISO 9237 "Determination of the air permeability of textile fabrics." In contrast to DIN EN ISO 9237, the flow velocity and the differential pressure are measured not perpendicular to the surface but along the surface. For this purpose, a defined distance channel defined by closed cover surfaces, into which an air flow is fed from one side, is measured.The differential pressure between inlet and outlet from the channel and the flow velocity at the air outlet are measured Flow velocities between 0 and 1 m / s are measured between 300 mm and 1300 mm long channels, which means that a spacer structure which produces no measurable flow at the backflow of up to 100 Pa and a flow channel length of 300 mm at the outlet is not suitable for the present invention should be.

Air passage opening: Includes at least one opening in the sole side lower peripheral area of the upper shaft material. Preferably, there are at least two approximately opposite air passage openings. The air passage openings can be introduced for example by means of punching, cutting or perforation in the upper shaft material. The shape of the air passage opening may be arbitrary such as round or square. The air passage opening can be protected against the ingress of foreign bodies with an air-permeable sheet-like protective material, for example in the form of a net or grid. The protective material may be hydrophobic. The total area of the at least one air passage opening is at least 50 mm ² and preferably at least 100 mm ² . In an alternative embodiment, the air passage opening can also be formed directly by an air-permeable material, which can be used as a shaft upper or part of the upper shaft material and inherently has the necessary air permeability, so no additional openings must be created.

Zwicken, Zwickklebung:

This is a type of attachment of the lower end region of a shaft layer, for example of the upper upper material or a shaft lining, on the underside of a mounting sole (for example, insole or air-permeable layer), as a rule by means of Zwickklebung. In this case, the sole-side still open shaft is stretched over a last, that the lower end portion of the upper shaft material is above the last and this projecting part of the upper sheath material is pulled by means of Zwickzangen on a lower-side peripheral edge of the mounting base and firmly glued there by Zwickklebstoffs. Panels:

An elongated piece of material fastened to a sole-side lower end region of the upper of the upper, which consists wholly or at least partially of air-permeable material and whose longitudinal dimension extends over the circumference of the upper or at least part of it. In the case according to the invention, one or more extension strips are fastened to individual circumference partial regions or over the entire circumferential region of the lower upper end of the upper material.

Cover strip (eg rubber edge): Elongated strip, in particular made of rubber or rubbery material, which surrounds the lower end of the shaft around its entire circumference or at least a large part thereof and provides protection for the shaft region covered with this strip, in particular abrasion protection. The cover strip may extend upwardly from the outsole. The cover strip may be integrated in the outsole or be a separate part from the sole.

The invention will now be further explained by means of embodiments.

FIG. 1 shows a first exemplary embodiment of a shoe 10 according to DE 10 2008 027 856, which has a shaft arrangement 12 and a sole 14 attached to the lower end region of the shaft arrangement 12, which in the case of this exemplary embodiment is an outsole. The shaft assembly 12 has in the usual way at its upper end a Fußeinschlüpföffnung 12 a, from which extends a lacing portion 12 b in the direction of the forefoot portion of the shaft assembly 12. In the lower end region of the shaft arrangement 12, a plurality of air passage openings 20 arranged around a part of the circumference of the shaft arrangement 12 can be seen. In the front part of the forefoot area, which corresponds approximately to the toe area of the shoe, no air passage openings are provided in this embodiment. The air passage openings 20 are uniformly distributed around the remaining peripheral region of the shaft assembly 12 at approximately the same distance from one another and are of circular design. Furthermore, the air passage openings 20 are provided with an air-permeable protective cover 22 to prevent the penetration of coarse particles such as stones. The protective cover 22 may cover the air passage opening from outside and / or from inside. A protective cover 22 may be associated with each individual air passage opening 20 or an entire protective cover 22 extends over all air passage openings. The protective cover 22 may be formed, for example, grid or net shape.

Figure 2 shows a second exemplary embodiment of a shoe 10 according to DE 10 2008 027 856, which largely coincides with the first embodiment shown in Figure 1, but differs from the first embodiment in terms of the arrangement and shape of the air passage openings 20. The air passage openings 20 of the shoe shown in FIG. 2 have a circumferential length of the shaft arrangement 12. Rectangular shape and are located in the forefoot area or heel area of the shaft circumference in the lower end of the shaft assembly. The air passage openings 20 also have a grid-shaped protective cover 22.

Figure 3 shows a third embodiment of a shoe 10 according to DE 10 2008 027 856, which largely matches the second embodiment shown in Figure 2, but differs from the second embodiment in terms of the arrangement of the air passage openings 20. Also in the third embodiment, the air passage openings 20 have an elongated rectangular shape in the circumferential direction of the shaft assembly 12. However, only in the forefoot area of the shaft circumference are air passage openings 20 which are at least approximately opposite in the transverse direction of the foot. The air passage openings 20 are covered with a grid-shaped protective cover 22. FIG. 3 also shows, as a representative of all embodiments of FIGS. 1 to 4, a device 45 by means of which the air passage openings 20 can be closed if required. The illustrated movable device 45 comprises means with which an at least water-repellent material temporarily closes the air passage opening 20. In the embodiment shown, by means of a sliding device, an at least water-repellent material can be pushed along the circumference of the shaft over the air passage opening 20 until it is closed. The sliding device can be provided for one air passage opening or for a plurality of air passage openings. The movable device 45 allows the air passage opening and thus the air-permeable layer (not shown) of the shaft assembly 12 to be temporarily protected against the ingress of liquids such as water. The closing of the air passage openings may also be advantageous in winter or in very cold temperatures, as this can prevent over-cooling of the foot. As a device for closing the air passage openings plug, slide, flaps, a circulating belt and all other closure mechanisms can be used. Possible materials for closing the air passage opening may be plastics, foams, coated textiles, TPU, TPE, silicone, polyolefins, polyamides vulcanizates.

Figure 4 shows a fourth embodiment of a shoe 10 according to DE 10 2008 027 856, which largely matches the first embodiment shown in Figure 1, but differs from the first embodiment in that the air passage openings 20 are formed by an air-permeable material, which extends around the entire circumference of the lower shaft portion. This makes it possible to achieve a particularly high air exchange between the air-permeable layer and the outside environment of the shoe 10, with a correspondingly effective removal of heat and moisture from the shoe interior to the outside environment of the shoe 10. The air-permeable material is part of the upper upper material. In one embodiment, this may be a separate perforated, lattice-shaped or reticulated material, which is fixed in the sole-side lower peripheral region of the upper shaft material to this, or the upper material itself is machined accordingly in this lower peripheral region, such as by punching or perforating. Mesh, lattice-like textiles, open-pore foams, air-permeable materials can be used as air-permeable material

Textiles and combinations of these materials are used. These materials may for example consist of polyesters, polyamides, polyolefins, TPE, TPU, vulcanizates.

All embodiments in FIGS. 1 to 4 have in common that at least two

Air outlet openings in the foot transverse direction or in the foot longitudinal direction are at least approximately opposite. As a result, an air flow through the air-permeable layer can form, which is conducive to the removal of water vapor and heat from the shoe interior by means of convection. The airflow can also be actively generated with a built-in fan.

The embodiments in FIGS. 1 to 4 can also be combined with each other.

FIGS. 5 to 9 each show a cross section through part of the forefoot region of a shoe 10 according to DE 10 2008 027 856, along the section line AA in FIG. 1. If such a section line is also shown only in FIG. 1, the cross-sectional views of FIG Figures 5 to 9 alike for the embodiments shown in Figures 2 to 4. Figures 5 to 9 each show a shaft assembly 12 with an attached sole 14, which represents an outsole in the illustrated embodiment. The embodiments shown in FIGS. 5 to 9 differ with regard to the respective shaft arrangement 12.

All of the shaft assemblies 12 of the embodiments in FIGS. 5-9 comprise a shaft upper 16 having a lining on the inside thereof, either a bootie functional layer 34 (FIGS. 5 or 9), a shaft functional layer 37 (FIGS. 6 or 7) or only a feed layer 18 without functional layer (Figure 8). In all five embodiments, a shaft bottom functional layer is located in the region of the shaft bottom 15. The shaft functional layer and the shaft bottom functional layer may be common parts of a functional layer boot 39 (FIGS. 5 or 9) or they may be separate functional layer parts which are sealed against each other (FIGS. 6 and 7). In FIG. 8, only the shoe bottom has a functional layer. In the embodiments illustrated, all these functional layers are part of a multilayer functional-layer laminate, in the illustrated embodiments of a three-layered gene functional layer laminate 24, 27 or 28 with a functional layer 34, 37 and 38, which is embedded between two sheets 25 and 26. The fabrics in FIGS. 25 and 26 may typically be one textile layer at a time. The shaft functional layer 37 or the shaft functional layer laminate 27 (FIGS. 6 and 7) or the lining layer 18 (FIG. 8) can be fastened to a mounting sole 30 by means of a stitching seam 32. Below the shaft bottom functional layer 38 or the shaft bottom functional layer laminate 28 there is an air-permeable layer 40 (FIGS. 5 to 9) at least approximately at the height of the at least one air passage opening 20. not shown) Zwickklebstoffs on the underside of the mounting base 30 (Figures 5 and 9) or the air-permeable layer 40 (Figures 6 and 7) zwickgeklebt. Or the sole-side lower end region of the upper upper material 16 is connected by means of a further Strobelnaht 33 with another mounting sole 30a (Figure 8).

In all embodiments shown in FIGS. 1 to 9, the upper material 16 is constructed with a material permeable to water vapor. Likewise, with material permeable to water vapor, the mounting sole 30 (FIGS. 6 to 8) arranged above the shaft bottom functional layer laminate 28 and the feed layer 18 (FIG. 8) are constructed. All of the layers of the shaft bottom located below the air-permeable layer 40, such as the mounting sole 30 in FIG. 5, the filling layers 31 in FIGS. 6 and 7 and the further mounting legs 30a in FIG. 8 need not have any water vapor permeability.

In the embodiments of FIGS. 5 to 9, the air passage openings 20 of the shaft upper 16 are located close to the bent region of the turned-in lower end region of the upper material 16, at such a height that the air passage openings 20 are at least approximately at the same level as the peripheral side surfaces 42 of the air-permeable layer 40. In order to achieve a particularly effective air passage between the air-permeable layer 40 and the air passage openings 20, the air passage openings 20 preferably have a vertical extent approximately equal to the vertical thickness of the air-permeable layer 40 and are the air passage openings 20th and the air-permeable layer 40 in the vertical direction relative to each other aligned so that a horizontal center plane of the air-permeable layer 40 and a central axis of the respective air passage opening 20 at least approximately the same verti kaier height li ay.

In all five embodiments, with the lower portion of the shaft assembly 12, the sole 14 is connected to the bottom of the impact forming lower end portion 16a of the upper upper 16 and to the lower portion portion of the shaft bottom, which is not covered by this impact, is in communication. A unevenness on the underside of the shaft bottom, in particular caused by a lasting impact 16a of the shaft upper 16, can be compensated by a filling layer 31. The sole 14 may be constructed with waterproof material which is rubber or a rubber-like elastic plastic, for example an elastomer. However, the sole 14 may also be made of material permeable to water vapor such as leather. The sole 14 may be a prefabricated sole which is glued to the shaft assembly 12, or a sole molded onto the shaft assembly 12. A running surface of this sole located on the underside of the sole 14 is provided with a groove pattern in the usual way in order to form profile projections which improve the slip resistance of the shoe 10 provided with such a sole 14. In all embodiments shown in FIGS. 5 to 9, an upper edge 14 a of the sole 14 terminates below the lower end of the respective air passage opening 20.

In a manner not shown, especially in the case of hiking or trekking shoes on the directly above the upper edge 14a of the sole 14 located area of the upper shaft material 16, ie where the at least one passage opening 20 is located, a mainly serving as scree rubber edge be attached For example, by adhering to the upper upper material 16 and the upper edge 14 a of the sole, for example, the same color as the sole 14 has. In order not to block the air permeability of the air passage openings 20, the rubber rim at the passage openings 20 corresponding points in turn provided with air passage openings.

In all embodiments of Figures 5 to 9, the air passage openings 20 are provided with an air-permeable protective cover 22 which is formed for example by a net or mesh of metal or plastic or by a textile material with high air permeability and thus high water vapor permeability. The protective cover 22 may be located on the outside (FIGS. 5, 6, 8 and 9) or the inside (FIG. 7) of the respective air passage opening 20. Either each air passage opening 20 is associated with its own protective cover 22 or each part of the air passage openings 20 or all air passage openings 20 is associated with a common protective cover strip which extends over the corresponding number of the air passage openings 20.

Figures 5 to 9 will now be considered in more detail.

In the embodiment according to FIG. 5, the functional layer on the inside of the shaft upper 16 and the functional layer on the upper side are the air-permeable Both are part of a sock-like bootie 39 which lines the entire shaft assembly 12 on the inside thereof except for the foot insertion opening 12a. Such a bootie is usually sewn together from several functional layer parts, wherein the seams are pasted over with waterproof seam sealing tape and made waterproof in this way. The bootie could also be made of one piece of material, which would no longer require the need to sew and seal it. In the embodiment shown in FIG. 5, the bootie is constructed with the already mentioned functional layer laminate 24. The shaft assembly 12 is thus waterproof and after addition of a sole 14 there is a waterproof shoe. The air-permeable layer 40 is arranged in the shaft bottom region immediately below the functional layer laminate 24 of the bootie 39. In this case, the air-permeable layer 40 extends over the entire shaft bottom region and is thus available to the entire sole of the foot for the steam and heat exchange. Below the air-permeable layer 40 there is the mounting sole 40, on the underside of which the end impact 16a of the lower side region on the side of the sole is fastened by means of Zwickklebstoff (not shown). Instead of using a separate mounting sole, it is also possible in certain embodiments to make the underside or lower support surface of the air-permeable layer 40 correspondingly stable, so that the twill wrapper can be attached to this underside. In such an embodiment, the air-permeable layer additionally assumes the function of a mounting sole.

In the embodiment according to FIG. 6, on the inside of the upper material 16 and in the region of the shaft bottom 15 there are separate functional layers 37 and 38 belonging to the shaft functional layer laminate 27 and the shaft bottom functional layer laminate 28, respectively. A wrapped sole side end portion 27 a of the shaft functional layer laminate 27 is sewn firmly to the mounting base 30 by means of a stitching seam 32. The shaft bottom functional layer laminate 28 is located below the mounting sole 30 and extends below the embraced end portion 27a of the shaft functional layer laminate 27 and is watertightly connected to the end portion 27a via a sealing material (not shown), for example in the form of a sealing adhesive, so that the shoe interior by the interaction of the mutually sealed functional layers 37 and 38 with the exception of Fußeinschlüpföffnung 12 a and the Schnurbereichs 12 b of the shoe 10 is completely waterproof, as when using a functional layer Bootie. It is also possible to waterproof the shaft bottom functional layer above the mounting sole to the shaft functional layer laminate. Since the shaft bottom functional layer 38 extends below the embossed end region 27a and thus beyond the strobe seam 32, the strobe seam 32 is also sealed by the shaft bottom functional layer 38. Immediately below the Schaftbodenfunkti- onsschichtlaminats 28, the air-permeable layer 40 is arranged. At the bottom or lower abutment surface of the air-permeable layer 40, the lasting weft 16a of the upper 16 is fixed by means of a Zwickklebstoffs (not shown). Thus, the air-permeable layer also assumes the function of a mounting sole. In principle, it would also be possible to provide a separate mounting base below the air-permeable layer. The unevenness on the underside of the shaft bottom 15 caused by the lasting impact 16a of the upper material 16 is compensated by the filling layer 31 in the manner already mentioned.

The embodiment shown in FIG. 7 differs from the embodiment shown in FIG. 6 only in that the protective cover 22 is not on the outside but on the inside of the upper material 16 directly along the peripheral side surfaces 42 of the air-permeable layer 40 and on the inside in front of the air passage opening 20 is arranged.

The embodiment shown in FIG. 8 differs from the embodiments according to FIGS. 5 to 7 on the one hand in that the upper 16 is provided with only one feed layer 18 but not with one shaft functional layer except for a lower region near the shaft bottom 15, and that there are two mounting soles and two strobe seams. The feed layer 18 has, at a bottom end on the sole side, a feed position 18a, which is connected to a mounting sole 30 by means of a stitching seam 32. The sole-side lower end region 16a of the upper upper material 16 is connected by means of a further Strobelnaht 33 with another mounting sole 30a. The shaft bottom functional layer 38, which may again be part of a shaft bottom functional layer laminate, has on its outer circumference an upwardly upstanding collar 38 a, which projects into a gap between the upper material 16 and the feed layer 18. Between the shaft bottom functional layer 38 and the Schaftbodenfunkti- onsschichtlaminat and the other mounting base 30a, the air-permeable layer 40 is arranged. The shaft bottom functional layer laminate may also be disposed above the mounting sole. However, in the embodiment according to FIG. 8, the upper shaft region is not watertight. Thus, the shoe according to Figure 8 is particularly suitable for use in which less wet from above than wet from below and from the side must be expected, ie for walking or hiking in a humid environment when it is not raining, or when you only stay in the rain for a short time.

The embodiment shown in FIG. 9 substantially corresponds to the embodiment shown in FIG. In contrast to Figure 5, the mounting base 30 is designed so that the air-permeable layer 40 directed towards the surface of the mounting base 30 rises at an angle in the middle and projects into the air-permeable layer. Thus, the lower Position surface of the air-permeable layer 40 is raised or compressed according to the angled elevation of the mounting base 30. As a result, within the air-permeable layer, two inclined planes are formed which, starting from the center, run downwards in the direction of the peripheral side surfaces 42 and thus facilitate the drainage of any water present in the air-permeable layer 40. Such a configuration of the mounting sole 30 can also be provided for the embodiments in Figures 5 to 8.

FIGS. 10 to 14 show, as examples, various embodiments of spacer formations 60 which are suitable for the air-permeable layer 40. All of these spacer structures is inherent in that they form two mutually spaced support surfaces, wherein the spacer structure rests with the lower support surface on the respective support and whose upper support surface serves as a support surface for the position located above the spacer structure, which in particular the bottom portion of the functional layer boat (Figure 5 or 9) or the shaft bottom functional layer laminate (Figures 6 to 8) is. The two bearing surfaces are either either each formed by a fabric, which are held by means of intermediate spacer elements at a distance from each other and of which at least the upper air-permeable (Figure 1 1). Or only the lower support surface is formed by a fabric, stand up from the spacer elements whose free ends form support points, which together have the function of the upper support surface (Figures 10, 12 and 14). Or there is neither a lower nor an upper sheet but a single sheet formed in a wave or zigzag shape with lower and upper crests or serrations defining the lower and upper bearing surfaces, respectively (Figure 13).

The spacers shown in Figs. 10 to 14 will now be considered in more detail.

In the embodiment of a spacer structure 60 suitable as an air-permeable layer 40, as shown in FIG. 10, approximately hemispherical projections or bulges 65 bulge upward from a lower sheet 64, whose upper peaks define an upper bearing surface. In one embodiment, this spacer structure 60 consists of an initially flat knitted fabric or of a solid material which, after being brought into the shape shown, is stiff or stiffened, for example by a deep-drawing process, in such a way that it also underlies the mold Maintains load, which it is exposed when walking with the shoe, which is equipped with this distance structure. In addition to a deep-drawing process, other measures already mentioned can be used, namely deformation and stiffening by means of a thermoforming process. molding process or impregnation with a resin for the desired shape and stiffness hardening.

Figure 11 shows an embodiment of a suitable as an air-permeable layer 40 stand-up structure 60, the upper and lower support surface are formed by two mutually parallel air-permeable sheets 62 and 64, which are selected for example from the group of polyolefins, polyamides or polyesters, wherein the sheets 62 and 64 are air-permeably connected to each other by supporting fibers 66 and spaced at the same time. At least a portion of the fibers 66 are arranged as spacers at least approximately perpendicularly between the sheets 62 and 64. The fibers 66 are made of a flexible, deformable material such as polyester or polypropylene. The air may flow through the sheets 62 and 64 and between the fibers 66. The fabrics 62 and 64 are open-pored woven, knitted or knitted textile materials. Such a spacer fabric 60 may be the aforementioned spacer fabric available from Tylex or Müller Textil.

The spacer structure 60 shown in FIG. 12 has a similar structure to the spacer structure shown in FIG. 10, but consists of a knit of knitted fibers or woven filaments which are brought into this shape and, for example, by a thermal process or impregnation with synthetic resin in this form be solidified.

FIG. 13 shows an embodiment of a spacer structure 60 with a zigzag or sawtooth profile, to which an initially flat material has been shaped such that the upper and lower vertices 60a and 60b define the upper or lower bearing surface of this spacer structure 60. Also, the spacer 60 of this shape can be formed by the already mentioned methods and solidified to the desired stiffness.

FIG. 14 shows a further exemplary embodiment of a spacer structure 60 which is suitable as an air-permeable layer 40. In this embodiment, spacers are formed by the single bottom sheet 68 not by protrusions or protrusions but by tufts 70 which are upstanding from the sheet 68 and whose top free ends together define the top support surface. The tufts 70 can be applied by flocking the lower fabric 68.

Embodiments of the invention or components thereof will now be considered and explained with reference to FIGS. 15 to 24. FIGS. 15 and 16 show embodiments of the finished design before and after the Operation, Figures 17 and 18, an embodiment of the Strobelmachart and Figure 19 again an embodiment of the Zwickmachart.

Although in the following embodiments, only the types of twining and stitching are considered, the invention is by no means limited thereto, but also applicable to all other types.

In the figures explained below, the same reference numerals are used for the same elements and features, even if they are embodiments of different design.

As far as terms such as above, below, above, below, vertically, horizontally and so on are used, this is related to the respective figure referred to and not taken absolutely.

FIG. 15 shows a partial construction of a first, twill embodiment of footwear 100 according to the invention in a partial sectional view in the forefoot area in a production stage, before a sole-side end region of a shaft 101 is crimped onto the underside of a peripheral region of a mounting sole 130, frequently also referred to as an insole.

This footwear 100 has a shaft arrangement 102 with the shaft 101 and a shaft bottom 15, with which the sole-side lower region of the shaft 101 is closed.

The shaft 101 has an upper 116 and on the inside thereof a shaft functional layer 234 and, in the illustrated embodiment, a shaft lining 225 on its inner side. Shaft bottom 115 has a shaft bottom functional layer 334 and, in the illustrated embodiment, a shaft bottom liner 335 on top thereof. In the region of the outer circumference of the shaft bottom 15, the shaft functional layer 234 and the shaft bottom functional layer 334 on the one hand and the shaft lining 225 and the shaft bottom lining 335 on the other hand are connected to one another via a common stroking seam 326. In order to seal the connection transition between the shank functional layer 234 and the shank bottom functional layer 334 at this seam, a sealing material 328 is located below the shank bottom functional layer 334 and a lower end region of the shank functional layer 234 which faces the shank bottom 15. Below the shank bottom functional layer 334 is an air-permeable layer 140, below which the mounting sole 130 is located. The actual upper material 16 ends at a distance above the air-permeable layer 140 and is extended there with a connecting material 210 which is connected to the upper upper material 16 by means of a seam 215 and which hangs downwards in the production stage shown in FIG an area between the seam 215 and the underside of the mounting sole 130 is permeable to air permitting the finished footwear 100 at the height of the air-permeable layer 140 an air exchange between a peripheral side surface 142 of the permeable layer 140 and the outside of the footwear 100. The lower end region of the connecting material 210, which is remote from the seam 215, hangs down so far down over the mounting sole 130 that it can serve as a connecting material winding edge 214 in a subsequent gapping process. On the outer side of the connecting material 210 is a cover strip 212, whose upper end portion covers the seam 215 and thus does not allow this seam 215 to be visible in the finished footwear 100. A lower end region of the cover strip 212 also hangs down over the plane of the mounting sole 130, so that its lower end region can serve as cover strip wiping edge 218 in a subsequent gapping process. In a region which is located at the level of the air-permeable layer 140, the cover strip 212 is formed permeable to air to allow air exchange between the air-permeable layer 140 and the outside of the cover strip 212.

In the illustrated embodiment, the bonding material 210 and the cover strip 212 have air-permeable areas whose vertical extent extends beyond both the top and bottom of the air-permeable layer 140. This not only ensures a particularly good air exchange between the air-permeable layer 140 and the outside of the footwear 100 but also ensures that even with, for example, tolerance-related vertical positioning differences of the connecting material 210 and / or the cover strip 212 relative to the air-permeable layer 140 in any case In the areas where the air-permeable areas of the cover strip come to lie in the region of the shaft, this additionally increases the climate comfort of the shoe, since the water-vapor-impermeable shaft cover is partially removed , For the desired air exchange between the air-permeable layer 140 and the outside of the footwear 100, it is sufficient if the connecting material 210 and the cover strip 212 are designed to be air-permeable only in the thickness range of the air-permeable layer 140, and it may already be sufficient if they are permeable to air Regions of bonding material 210 and masking strips 212 extend over only a portion of the thickness of the air permeable layer 140. An example in which both the joining material 210 and the cover strip 212 are designed to be permeable to air approximately in the vertical region corresponding to the thickness of the air-permeable layer 140, shows a second embodiment of the invention likewise shown in FIG. 16.

FIG. 16 also shows a partial sectional view in the forefoot area of footwear 100 with the partial structure similar to that of FIG. 15, but after the process of tying the sole-side lower end region of the upper 101 onto the underside of the mounting sole 130 and after attaching a sole 114, in FIG illustrated embodiment of an outsole, also called outsole. In contrast to the embodiment shown in FIG. 15, the shaft functional layer and the shaft bottom functional layer are part of a functional layer boot 134, that is to say a sock-like functional layer insert. In the same way, the lining provided in this embodiment consists of a feed boot 125, which has a shaft lining region and a shaft bottom lining region. In the usual way, the functional layer boat 134 and the bait boat 125 may each be part of a functional layer laminate boat 139.

Otherwise, the embodiments of FIGS. 15 and 16 coincide with one another.

FIG. 16 shows that, in this embodiment, both the connection material 210, which may be net or lattice-like at least in the air-permeable region, and the cover strip 212 are nipped on the underside of the mounting sole 130. In the embodiment shown in FIG. 16, first of all, in a first pinching operation, a connecting material twine impact 214 is pinched onto the underside of the mounting sole 130 by means of a joining material adhesive 216. In a subsequent second pincushion operation, a cover stripe turn-up insert 218 is then pinched onto the underside of the bonding material stiffener 214 by means of a cover stripe adhesive 220.

It is also possible to join together the splice tie wrapper 214 and the flapper wrapper 218 prior to the nip operation, and secure it to the underside of the mounting sole 130 in a single nip with a single layer of Zwickklebstoffbstoffs.

As FIGS. 15 and 16 show, the actual upper material 16 stops above the air-permeable layer 140, so that the peripheral side surface 142 of the air-permeable layer 140 remains uncovered by the upper material 116. Also, the attachment point, for example, an interface formed by a seam 215, between upper 116 and Connecting material 210 is located above the air-permeable layer 140. Since the connecting material 210 is air-permeable at least in that region in which it faces the peripheral side surface 142 of the air-permeable layer 140, a largely unimpeded air exchange between the air-permeable layer 140 and the outside of the connection material 210.

The cover strip 212, for example in the form of a band made of rubber or rubber-like material, is permeable to air at least in that region which lies at the height of the circumferential side surface 142 of the air-permeable layer 140, so that a largely unimpeded exchange of air between the air-permeable layer 140 and the outside of the cover strip 212 may take place.

In the embodiment shown in FIG. 16, the cover strip 212 has a projection over the fastening region (seam 215) between the connection material 210 and the outer material 116 on its upper longitudinal side, as seen in FIG. 16, so that this fastening region is covered by the cover strip 212. Thus, the cover strip 212 serves in this area on the one hand to keep this attachment area invisible in the finished footwear, and on the other hand to protect this attachment area against mechanical damage. In one embodiment, if the connection between upper 116 and joining material 210 is made by means of the seam 215 shown in FIG. 16, which has some sensitivity to mechanical rubbing and whetting, covering this seam 215 with the cover strip 212 will ensure the reliability and durability of the Footwear 100 significantly improved.

Because of the lasting impacts 214 and 218, a step is formed on the underside of the peripheral region of the mounting sole 130, which would lead to a cavity between the mounting sole 130 and the sole 114 applied later below the mounting sole 130. In order to avoid such a cavity, a filling layer 222 is applied to a central region of the mounting base bottom, which is located within the Zwickinschläge 214 and 218. If then after completion of the shaft assembly

102, the shaft bottom 115 - seen in Figure 16 - from top to bottom of the shaft bottom portion of the functional layer 134, the air-permeable layer 140, the mounting sole 130 and the filling layer 222, optionally, as in the embodiment shown in Figure 16, one in particular as Lining serving textile layer 125 on the inside of the functional layer 134, the sole 1 14 is applied, in the case of the embodiment in Figure 16 in the form of an outsole, this lies thanks to the filling layer 222 at a substantially flat bottom of the shaft bottom 1 15. The sole 1 14 may be a sole glued to the shaft bottom 15 or a sole attached to the shaft bottom 15. splashed sole act. Both sole types are equally suitable for footwear 100 according to the invention.

Figures 17 and 18 show a third embodiment of footwear according to the invention, which largely coincides with respect to the formation of the shaft assembly 102 with the first embodiment shown in Figure 15. Deviation exists in that in the third embodiment according to FIGS. 17 and 18, on the one hand, the lower end region of the connecting material 210 is connected to the mounting sole 130 by means of a seam 330, which may be a stitching seam, and, on the other hand, the lower end region the Abdeckstreifens 212 does not leak into a horizontal impact, as in the embodiments of Figures 15 and 16, but extends vertically as a whole. As shown in FIG. 18, which illustrates the shoe structure after the subassembly shown in FIG. 17 has been provided with the sole 114 and the cover strip 212, the cover strip 212 extends at its lower end in vertical alignment to the upper edge of the sole 114. In this embodiment, the cover strip 212 can be attached after the sole 1 14 has been attached to the shaft bottom 115, either by sticking to the shaft bottom 115 or by injection molding on the shaft bottom 15.

FIG. 19 shows a fourth embodiment of the invention according to the invention, before the operations of gusseting and attaching a sole 114 are performed, which are not illustrated for this embodiment, but can be carried out according to FIG. This fourth embodiment is largely consistent with the first embodiment according to FIG. 15 with regard to the shaft and shaft bottom structure. A deviation from FIG. 15 is that the connecting material 210 is the material of the air-permeable layer 130, which is vertically upwardly from the peripheral edge of the air-permeable layer 140 and connected to the lower end of the upper 116 by means of the seam 315. Notwithstanding FIGS. 15 and 16, in the fourth embodiment according to FIG. 19, only a single pinching operation is required, namely in order to fasten the covering strip winding insert 218 to the underside of the mounting sole 130 by means of gusseting. In particular, when the cover strip 212 is air-permeable over a large part of its vertical extent between the seam 215 and the mounting sole 130, a large-area air exchange with the outside of the footwear 100 can take place via the connecting material 210 formed by the material of the air-permeable layer 140.

For all of the above-described embodiments, the joining material 210 and the cover strip 212 each begin at least above a lower side of the air-permeable layer 140 and extend over at least a portion of the thickness of the air-permeable layer 140. permeable layer 140 extending vertical area are permeable to air.

FIGS. 20 and 21 show two exemplary embodiments of a connection material 210 suitable for footwear 100 according to the invention. In both figures, it is indicated on the basis of the respective lateral tear lines that this is only a section of a connecting material, which in reality has a greater longitudinal extent.

Figure 20 shows a schematic representation of a first exemplary embodiment, in which the connecting material 210 is constructed for example of a net-like or lattice-like material and is formed over its entire width extent with the same opening size, so over its entire longitudinal and widthwise extension has the same air permeability per unit area.

Figure 21 shows a schematic representation of a second exemplary embodiment, in which the opening size of the connecting material 210 in an upper part 210a of its width extension is greater than in a remaining lower part 210b of its width extension, to a particularly good adaptation to the different requirements in the upper part 210a of its width extension and to create in the lower part 210b of its width extension. Due to the larger opening size in the upper part 210a of the widthwise extension, where this connecting material 210 faces the peripheral side surface 142 of the air permeable layer 140, a higher air permeability is achieved than in the lower part 210b of its width extension with the smaller opening size there, which at least partially forms the connecting material wrapping 214 and there should have a particularly high mechanical strength in order to take the Zwickkräfte or other types of fastening forces particularly well. But it is also possible, only the upper part 210a of the width extension of the connecting material 210 with luftdurchlässigem material, for example in the form of latticed material, reticulated material, textile mesh or perforated air permeable material build, while the lower part 21 Ob the width of the extension Connecting material 210 is constructed with a material without air permeability, but with a particularly high fastening force resistance.

FIGS. 22 and 23 show exemplary embodiments of the cover strip 212 suitable for the footwear 100 according to the invention. Also in this case, it is indicated by the respective lateral tear lines that the respective illustration is only a partial section of the respective cover strip. In order to provide a particularly high mechanical protective function for the lower region of the shaft 101, ie where, for example, a hiking shoe, also called trekking shoe, which is to be suitable in particular for mountain migrations, is exposed to particularly high impact, friction and waving loads, For the cover strip 212, it is possible to use particularly robust material, for example in the form of a strip of rubber, rubber-like plastic or robust textile whose robustness is improved, for example, by coating the textile with a rubber-like mass.

One possibility is to also build the cover strip 212 with an air-permeable material to the finished footwear at the height of the air-permeable layer

140 to ensure the desired air permeability of the air-permeable layer 140 to the outside of the cover strip 212. In the embodiments illustrated in FIGS. 22 and 23, the cover strip 212 is constructed with an inherently air-impermeable material which can be made particularly robust, and through-openings in that region of the cover strip 212 which faces the air-permeable layer 140 in the finished footwear formed, which allow the desired air permeability.

In the embodiment shown in FIG. 22, the cover strip 212 has recesses 213 spaced apart from one another in its longitudinal extension direction, which extend to the lower longitudinal edge of the cover strip 212 so that the cover strip 212 is open at these points. Behind the recesses, the connecting material 210 runs.

In the case of the embodiment shown in FIG. 23, the cover strip 212 is formed in spaced-apart areas in its longitudinal extension direction by corresponding perforations with grid zones 217 which allow the desired air permeability at the required locations. In this embodiment, the portion of the cover strip 212 located below the grating zones 217 remains unattenuated, ie in the region which forms the cover strip turn-up 218, so that a cover strip 212 of the embodiment shown in FIG. 23 is particularly well suited for a fastening process or other fastening process absorb occurring forces. In addition, the lower portion of the cover strip 212 of Figure 20 can be better grasped with the nip pliers used for clinching than the cover strip 212 of Figure 19 having gaps 213, particularly if nip pliers are used, each of which occupies only a relatively small length of the cover strip 212 grab. The embodiment in FIG. 23 can also be designed such that the openings are arranged uniformly over the entire surface and over the entire width and length of the cover strip 212.

FIG. 24 shows as a design example a lateral plan view of a part of the footwear 100 according to the invention, with a part of the upper 116 of the upper 101 at the top, a part of the sole 114 underneath the cover strip 212 and in its air passage openings the mesh-like or mesh-like connecting material in this case 210 can be seen.
