Description

SHAFT ASSEMBLY FOR FOOTWEAR AND FOOTWEAR HAVING SAID SHAFT ASSEMBLY}

The present invention relates to a shoe shaft device and a shoe comprising the shaft device.

Shoes are known in the art that have a waterproof and water vapor permeable shaft and are capable of releasing sweat moisture to the outside despite being waterproof in the shaft area. In order for the sweat moisture to be discharged from the sole area and also to the outside, the sole area of the shoe may also be provided with waterproof and water vapor permeable sole functional layers. One example is known from DE 10 2008 029 296 A1 in which the shaft bottom as well as the remaining shaft area are water vapor permeable but are equipped with waterproof functional layers and the shaft bottom is separated from the shaft area.

Such shoes, however, can cause the problem that spots appear on the outer material at the lower end of the shaft area and that the feet feel unpleasant cold, especially in cold weather.

The present invention therefore provides a shaft arrangement for a shoe and a shoe comprising the same, in which such unpleasant cold air does not occur in the end section of the shaft region in front of the shaft bottom and preferably also prevents staining on the external material at this location. It aims to provide. The invention also aims to ensure that breathability is ensured at such a location.

This object is achieved by the subject of the independent claims. Advantageous embodiments will emerge from the dependent claims.

The shoe shaft device of the present invention comprises a shaft bottom having a water vapor permeable installation sole and a shaft bottom functional layer laminate and a shaft region having an outer material ply and a liner ply. The sole side shaft end region is connected to the peripheral edge of the shaft bottom. To this end, there are a number of design attempts, which will become apparent in the description below.

The laying sole may have openings and may be of water vapor permeable material.

Next, the present invention provides a shaft from the region between the outer material ply of the shaft region and the liner ply so that moisture is transported from the region between the outer material ply of the shaft region and the liner ply to the region below the stack of shaft bottom functional layers. A suction element is provided that extends to the area under the stack of floor functional layers. From there, moisture can also be transported outwards through the through-holes or voids of the sole unit, especially in the case of a shaft device connected to the sole unit.

In accordance with the underlying aspects of the present invention, the inventors have found that where moisture is mainly collected and often condensed to form liquid water, it is in particular the shaft end region which is generally waterproofly connected to the peripheral edge of the shaft bottom. As a result, the foot area opposite the liner ply feels cold there, and if the liner ply consists of a shaft functional layer, there is no longer sufficient water vapor gradient between the inner and outer surfaces of the shaft functional layer. In this area, the breathability is markedly reduced or no longer present, and the outer surface of the shoe exhibits water stains on the vapor permeable external material ply, which detracts from the shoe's appeal and appearance. The formation or joining of the mold may corrode, which in the worst case will destroy the shoe.

It is a basic concept of the present invention to provide an additional suction member of absorbent material to extend into the end section of the shaft region where moisture is normally collected and from there under the shaft bottom functional layer stack. This type of suction member guides moisture from the space between the outer material ply and the liner ply to the area under the shaft bottom functional layer stack in the end section of the shaft region adjacent the shaft bottom, where the moisture penetrates the sole unit. It may exit from the shoe, in particular downwards through holes or voids. This prevents unpleasant cold air in that area, maintains breathability in that area, and reliably prevents staining and corrosion of the joints. The suction member may be called a wicking tape in that it has the function of a wick. Such a suction member may be provided in a plurality of shaft devices for shoes as will be apparent below.

In all embodiments, the liner ply may be suitably connected to, for example, an outer material sewn on the upper side.

In the first embodiment of the present invention, the liner ply is composed of a shaft functional layer laminate in order to ensure water vapor permeability / breathability and waterproofness at the same time.

In a further embodiment of the invention, at least one suction member is formed in a band shape. This is a type that is simple to achieve in terms of manufacturing technology and ensures very reliable removal of the liquid.

In a further embodiment of the present invention, at least one suction member extends from a predetermined section of the sole side peripheral edge of the shaft area to a section of the sole side peripheral edge located on the opposite side, in particular in the shoe transverse direction. This suction member thus extends into the interspace between the outer material ply and the liner ply, transporting moisture from both interspaces down the shaft bottom functional layer stack. This is a very advantageous embodiment which is simple to achieve in terms of manufacturing technology.

In a further embodiment of the invention, the at least one suction member is adapted to extend over at least 25% of the section of the sole side peripheral edge of the shaft region, in particular over the forefoot section of the sole peripheral edge of the shaft region. Has a width of size. This makes it possible to maximize the removal of the liquid as much as possible.

In a further embodiment of the invention, continuous removal of liquid from all the circumferential regions of the shoe is ensured, and a plurality of suction members, in particular tape-shaped suction members, are arranged along the sole side peripheral edge of the shaft area.

In a variant embodiment, exactly one suction member is arranged at the sole side peripheral edge of the shaft area. What should be done here is to provide such a suction member at the circumferential point of the shaft device where the most water is generated, for example in the forefoot area of the shaft device.

The suction member may in principle be made of any material which absorbs and carries moisture. It will be found that cotton is an advantageous material.

The suction member according to the invention can be fixed in various ways with respect to the shaft device. In order to pass the transition between the shaft end region and the shaft bottom, this suction member must pass through the connection provided therebetween. In practice, this suction member is often placed on a cured dot of adhesive applied circumferentially to the outer material ply. The suction member may also be sewn to the laying sole and / or external material ply at one or more locations.

In order to securely hold the suction member, an adhesive may be provided at least locally. In particular, the suction member may be cemented to the bottom of the shaft bottom functional layer stack in order to be secured to the bottom of the shaft bottom functional layer stack.

In order to convey sufficient moisture from the interspace between the outer material ply of the shaft region and the liner ply, the suction member is advantageous if its interspace section extends about 1 to 3 centimeters into the interspace, in particular about 2 centimeters. Do.

In order for the water sucked in the interspace and carried to the area under the shaft bottom functional layer stack to be further transferred to the periphery, the suction member has its shaft bottom functional layer stack side section with the shaft bottom functional layer stack. It would be advantageous to extend about 1 to 4 centimeters, especially about 3 centimeters, to the area below.

Thus, in an advantageous embodiment of the invention, an overall length of 3 to 7 centimeters, preferably about 5 centimeters, can be obtained for the suction member.

In one configuration of the shaft arrangement of the present invention, a water vapor permeable laying sole, sometimes also known as an insole, is disposed over the shaft bottom functional layer stack. In this case, the suction member has its shaft bottom functional layer stack side section extending above the outer surface of the shaft bottom. This configuration can be used to achieve particularly effective water removal, since moisture from the shaft bottom functional layer stack side section can be transferred directly to the surroundings.

In this configuration, the water vapor permeable laying sole can be sewn to the sole side end region of the shaft functional layer stack by, for example, a Strobbel stitch or a zigzag stitch, and further the sole side of the outer material ply of the shaft region. The end region can be lasted on the bottom of the shaft bottom functional layer stack.

In a variant configuration of the shaft device, sometimes also called a bootie, the sole end region of the shaft functional layer stack is sewn to the peripheral edge of the shaft bottom functional layer stack, for example by a zigzag stitch, and via a waterproof sealing tape. Are sealed waterproof against each other. In this kind of configuration, a water vapor permeable laying sole is disposed below the shaft bottom functional layer stack.

Next, in this configuration, there is a first modification in which the sole-side end region of the outer material ply is sewn to the water-permeable laying sole. In this case, the suction member extends from the space between the outer material ply and the shaft functional layer stack to the space between the shaft bottom functional layer stack and the water vapor permeable laying sole. Moisture transported from the space between the outer material ply and the shaft functional layer stack to the area below the shaft bottom functional layer stack must still penetrate the water vapor permeable laying sole to allow it to be transported out. This configuration has also been determined to be able to achieve a sufficient rate of water removal.

In a variant configuration, the sole side end region of the outer material ply is lasted on the bottom of the laying sole, in which case the suction member extends to the outer surface of the shaft bottom. This makes it possible to obtain particularly good moisture removal.

In principle, the shaft arrangement of the present invention is not limited to a particular structure, but finds utility in many structures. The structure of the shaft bottom functional laminate and the shaft functional layer laminate is not critical.

The invention also provides a shoe having at least one shaft device of the type described above and having a sole unit fixed thereon. The sole unit may be connected to the shaft device in any desired manner, preferably by bonding or injecting the sole unit to the shaft device. Sole units capable of ensuring sufficient moisture removal should be provided with at least one through opening or void leading outwards in a downward or lateral direction.

Definition and test method

shoes:

A foot cover having a closed upper portion (shaft device) that includes an opening for pushing the foot and includes at least one sole or sole unit.

Shaft Outer Material :

Forming the outer surface of the shaft and even the outer surface of the shaft device, for example, it is made of or made of leather, fabric, plastic or other known materials or combinations thereof, and is a material composed of a material which is generally water vapor permeable. The sole-side lower end of the shaft outer material is adjacent the upper edge of the sole or sole unit or forms an area on the interface between the shaft and the sole or sole unit.

Laying outsole (insole) :

The laying sole is part of the shaft bottom. The sole side lower shaft end region is fixed to the laying sole.

Sole:

The shoe has at least one outsole, but may also include a plurality of types of sole ply disposed up and down to form the sole unit.

Outsole:

The outsole is the part of the sole area that is in contact with the floor / ground or in major contact with the floor / ground. The outsole has at least one tread surface against the floor.

Midsole:

When the outsole is not directly attached to the shaft device, a midsole may be inserted between the outsole and the shaft device. The midsole may serve, for example, as a cushioning, damping or filling material.

Bootie:

The bootie is a sock type inner liner of the shaft device. The bootie forms a bag type liner of the shaft device, which essentially completely covers the interior of the shoe.

Functional layer:

Waterproof and / or water vapor permeable layers in the form of membranes or appropriately treated or finished materials, such as plasma treated fabrics. The functional layer in the form of a shaft bottom functional layer may form at least one ply of the shaft bottom of the shaft device, but may also be provided as a shaft functional layer that at least partially lining the shaft. The shaft bottom functional layer as well as the shaft functional layer may be part of a plurality of layers, usually a two-, three- or four-ply membrane stack. The shaft functional layer and the shaft bottom functional layer may each be part of the functional layer bootie. If a shaft bottom functional layer and a separate shaft bottom functional layer are used in place of the functional layer booties, they are sealed to be waterproof against one another, for example, in the sole region of the sole side of the shaft device. The shaft bottom functional layer and the shaft functional layer may be formed from the same or different materials.

Suitable materials for waterproof water vapor permeable functional layers include polyetheresters and their laminates, in particular polyurethanes, polypropylenes and polyesters, as described in the printed literature such as US-A-4,725,418 and US-A-4,493,870. to be. In one embodiment, the functional layer is constructed using microporous expanded polytetrafluoroethylene (ePTFE) as described, for example, in printed literature such as US-A-3,953,566 and US-A-4,187,390. In one embodiment, the functional layer is constructed using expanded polytetrafluoroethylene equipped with a hydrophilic impregnant and / or hydrophilic layers (see, eg, printed document US-A-4,194,041). The microporous functional layer has an average pore size between about 0.2 microns and about 0.3 microns.

Laminate:

A laminate is generally an assembly consisting of a plurality of plies that are durablely bonded to one another by being attached together. In the case of a functional layer laminate, the waterproof and water vapor permeable functional layer is equipped with at least one fabric ply. At least one woven ply serves primarily to protect the functional layer during its treatment. This is called a two-ply laminate. The three-ply laminate consists of a waterproof and water vapor permeable functional layer embedded between two woven plies. Bonding between the functional layer and the at least one woven ply is made, for example, by an adhesive continuous water vapor permeable layer or by a discontinuous layer of non-water vapor permeable adhesive. In one embodiment, an adhesive in the form of a dot-shaped pattern may be applied between the functional layer and the woven ply or between both woven plies. The pointed or discontinuous application of the adhesive is chosen because a uniform layer of adhesive that is itself non-water vapor permeable may block the water vapor permeability of the functional layer.

Barrier fly:

Barrier plies are particularly suitable for the penetration of material in the form of particles or foreign matter, for example small stones, through the ply of material to be protected, in particular through a mechanically sensitive functional layer or functional layer membrane. It acts as a barrier.

Waterproof:

The functional layer / functional layer laminate / membrane (including the appropriate seams provided in the functional layer / functional layer laminate / membrane, if appropriate) is waterproof if it guarantees a water inlet pressure of at least 1 * 10 ⁴ Pa. Preferably, the functional layer material ensures a water inlet pressure of at least 1 * 10 ⁵ Pa. The water inlet pressure is measured by the following test method, ie 20 to a sample of 100 cm ² functional layer. Distilled water at ± 2 ° C. is added with increasing pressure The pressure increase of water is 60 ± 3 cm hydrohead per minute The water inlet pressure is then equal to the pressure at which water first appears on the other side of the sample. Details of the process are specified in ISO standard 0811 (1981).

Whether the shoe is waterproof can be tested using centrifugal devices of the kind described in, for example, US Pat. No. 5,329,807.

Water vapor permeability:

The functional layer / functional layer laminate is considered to have water vapor permeability when it has a water vapor permeability (Ret) of 150 m ² * Pa * W ^-1 or less. 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).

As an exemplary embodiment, all the shoes described below have a sole unit and a shaft device fixed thereto. In the exemplary embodiment described below, the sole unit is bonded to the shaft device. Similarly, it is also possible to inject the sole unit into the shaft device.

All the description below is schematic and does not necessarily need to be practical in terms of dimensions and scale.

1 shows a cross-sectional view of the forefoot area of a first shoe according to a first embodiment of the invention.

The first shoe 2 comprises a sole unit 4 and a shaft arrangement 22, which are connected to each other.

The shaft device 22 comprises a shaft bottom 34 and a shaft region 23 connected to it at the peripheral edge of the shaft bottom 34, in FIG. 1 the left and right sides of the shaft region 23 which are mirror symmetric with each other. The shaft section is shown. The upper section of the shaft region 23 is not shown in Figures 1 and below for simplicity.

The shaft region 23 comprises a vapor permeable outer material ply 24 and a shaft functional layer stack 26, which goes from outside to inside, and has a netband or mesh 28. , A shaft functional layer or shaft membrane 30, and a shaft liner 32.

The sole-side lower end region of the outer material ply 24 is bent inward relative to the essentially vertical section and secured to the plural layers of shaft bottom 34 by a lasting adhesive 44.

A plurality of shaft bottoms 34 are stacked from top to bottom, with a shaft bottom functional layer 40 and a bottom support fabric ply 42 disposed below and with a laying sole or insole 36. A sieve 38. The laying sole 36 is also connected to the sole side end region of the shaft bottom functional layer stack 38 via a stitch 46, such as a strobel stitch or a zigzag stitch, at its peripheral edge.

Thus, the shaft bottom functional layer stack 38 is composed of two layers of stacks. As is apparent from FIG. 1, the shaft bottom functional layer stack 38 is waterproof to the sole side end region of the shaft functional layer stack 26 and the outer material ply 24 by the laying sole 36, for example, by bonding. It has a larger lateral dimension than the laying sole 36 so that it can be connected.

The sole-side lower end region of the outer material ply 24 is lasted on its upper surface below the peripheral edge of the shaft bottom functional layer stack 38 by the lasting adhesive 44.

The sole bottom lower end region of the shaft functional layer stack 26 is raised from the sole bottom lower end region of the outer material ply 24. This creates an interspace in the end section of the shaft region 23 between the shaft functional layer stack 26 and the outer material ply 24, which widens towards the end section of the shaft region 23.

The shaft bottom functional layer stack 38 extends slightly into the interspace. The portion of the interspace not occupied by the end region of the shaft bottom functional layer stack 38 is generally filled by air or by steam or by a mixture thereof.

In addition, the lower portion of the sole side end region of the shaft functional layer stack 26 is surrounded by the stitching 46 or the shaft bottom functional layer stack 38 by a waterproof sealing adhesive 48 while excluding the stitching 46. It is connected to the upper surface of the peripheral edge of the, so that a shaft device having an overall waterproof property is obtained, or a shaft device having an overall water vapor transmission property is obtained when using the waterproof layers as well as the water vapor permeable functional layers 26 and 38.

This sealing adhesive 48 penetrates the net band 28, thus sealing the two functional layers against each other, and fixing the shaft bottom functional layer laminate 26 to the shaft functional layer laminate 26 and It serves as a seal, so that no additional adhesion is required for this.

The sole unit 4 is made in advance and fixed to the sole side lower end region of the outer material ply 24 by a sole adhesive applied to at least the upper surface of the peripheral edge region of the sole unit 4. In the present exemplary embodiment, the first sole adhesive layer 20 is applied to the upper surface of the peripheral edge region of the sole unit 4, and the second sole adhesive layer 50 is applied to the sole side lower end region of the outer material ply 24. ) Is applied.

The sole unit 4 comprises a sole ply 6 which extends slightly upward to define its peripheral outer area and to accommodate the curved area of the outer material ply 24 on its upper surface. Going in the direction, it has a support bar ply 8, a barrier ply 16, and a central incision in which a comfort ply 10 with a comfort bar is disposed on the barrier ply 16.

As can be seen in FIG. 1, the adhesive layer 20 extends over the top surface of the sole ply 6 and the top surface of the comfort bar of the comfort ply 10. Only the area of the right section of the sole ply 6 located below the right end of the shaft bottom functional layer stack 38 and the comfort bars of the comfort bar ply 10 adjacent thereto are configured without the adhesive layer 20. Can be.

FIG. 1 shows three support bars of the support bar ply 8 and three comfort bars of the comfort ply 10 constructed slightly wider than these support bars and disposed below it. The comfort bar 10 further includes narrower comfort bar sections starting at the inner surface of the sole ply 6.

The bottom of the sole ply 6 and the support bar ply 8 consists of a running or tread surface 14. Between the support bars of the support bar ply 8, there are incisions or sole ply through openings 12 configured to provide water vapor permeability and / or air permeability to the sole ply 6 with the support bars 8. exist.

The sole ply 6 can be in one piece, as shown in the figure, or in two or more pieces, for example in different colors.

The sole ply through opening 12 is made as wide as possible so that high water vapor permeability can be provided correspondingly to the sole ply 6 with support bars 8 and further to the sole unit 4.

The sole unit 4 is horizontally traversed by the barrier ply 16 as mechanical protection against the shaft bottom functional layer stack 38 against damage by foreign matter such as small stones, for example, through the sole ply. It functions as the opening 12. This barrier ply 16 extends slightly into the sole ply 6 to be secured to and durable connected to the sole ply 6. This barrier ply 16 of one embodiment may be made using a thermally compacted fibrous material, and may additionally also be configured as a stabilizing material for the sole unit 4.

Support bar ply 8 and comfort ply 10 are soles, as indicated by different hatching lines, to achieve reduced weight for sole unit 4, improved walking comfort for lower foot cushions, or both. It may be made of a material different from the ply 6. Instead, the support bar ply 8 and the comfort ply 10 and the sole ply 6 may be made of the same material.

In particular, a softer material may be selected for the support bar ply 8 and the comfort ply 10 than the material of the sole ply 6. EVA is an example of a suitable material for the support bar ply 8 and / or the comfort ply 10 if a good underfoot cushion should be obtained. For weight reduction to be achieved for sole ply materials, foamed plastics with a correspondingly low specific gravity are suitable. For example, foamed EVA is suitable if both improved underfoot cushioning and weight reduction are achieved for the sole ply material. However, there are many additional variations of materials that can be used.

Beneath the barrier ply 16, a decorative ply 18 is optionally located which can be seen from below and which gives the sole unit an attractive appearance.

2 shows a cross-sectional view of the forefoot area of the second shoe 52 according to the second embodiment of the invention.

Like the first shoe 2, the second shoe 52 likewise comprises a shaft device 70 connected with the sole unit 54. The shaft device 70 is constructed in accordance with the principle of a bootie and also shows a shaft bottom 80 and left and right shaft sections connected to it at the peripheral edge of the shaft bottom and mirror symmetric with each other in FIG. 2. Shaft area 71.

Shaft region 71 comprises a water vapor permeable outer material ply 72 and a three-ply shaft functional layer stack 74, which shaft functional layer stack 74 includes an inner shaft liner 78 and an outer shaft. Functional layer or membrane 76 and woven lattice or mesh 75.

The outer material ply 72 of the shaft region 71 extends slightly further than the shaft functional layer stack 74 extends in the direction of the shaft bottom 80. The shaft functional layer stack 74 is connected to the shaft bottom functional layer stack 84 of the shaft bottom 80 by sewing, which may in particular be performed in a zigzag stitch, and the sewing 90 is a seam sealing tape 92 Is sealed waterproof to the outside.

The shaft bottom functional layer stack 84, like the shaft functional layer stack 74, has a two-ply configuration with an inner support fabric ply 88 and an outer shaft bottom functional layer or membrane 86. The fabric plies 78, 88 of the functional layers 76, 86 and also the shaft functional layer stack 74 and the shaft bottom functional layer stack 84 are fabric plies 78, 88 and the functional layer 76. , 86) are sewn together so that each is continuous with each other.

2 shows the separation between the outer surface of the shaft functional layer 76 and the inner surface of the outer material ply 72, but in practice these surfaces may also be directly adjacent to each other.

Surrounded by the outer material ply 72 of the shaft region 71 and sewn to the sole side end region of the outer material ply 72 are disposed below and with the shaft bottom functional layer stack 84. Laying outsole or insole 82 having a slightly smaller size in comparison. Sewing 94 between the sole side end region of the outer material ply 72 and the peripheral edge region of the laying sole 82 may be performed in particular with a strobel stitch or a zigzag stitch.

Like the sole unit 4 of the first shoe 2, the sole unit 54 of the second shoe 52 may be prefabricated and secured to the sole side lower end region of the outer material ply 72. Further, it is fixed to the bottom free area of the sole side of the laying sole 82 by a sole adhesive applied to at least the upper surface of the peripheral edge region of the sole unit 54.

In this embodiment, the first sole adhesive layer 68 is applied to the upper surface of the peripheral edge region of the sole unit 54, and the second sole adhesive layer 96 is the sole side lower end region of the outer material ply 24 and It is applied to the marginal area of the sole side of the laying sole 82.

Like the sole unit 4, the sole unit 54 has a sole ply 56 which forms an outer area surrounding the sole unit 54 and is provided with a central incision, which is shown in FIG. By way of example, the support bar ply 58 and the barrier ply 64 having three support bars are arranged from top to bottom. The barrier ply 64 traverses the sole unit 54 horizontally and its peripheral edge region extends into the upper end of the sole ply 56. It is therefore reliably connected to the sole ply 56. The support bars extend from the barrier ply 64 to the plane of the lower side of the sole ply 56, and the bottom of the sole ply 56 and support bar 58 form a running or tread surface 62. Unlike the sole unit 4 of the first shoe 2, the sole unit 54 does not have an additional comfort ply, but can be added if necessary.

An optional decorative ply 66 to be provided below the barrier ply 64 corresponds to the decorative ply 18 of the first sole unit 4.

In the case of the shaft device 22 of the first shoe 2 of FIG. 1 and the shaft device 70 of the second shoe 52 of FIG. 2, each shaft bottom functional layer stack 38, 84. ) Has a two-ply configuration and includes only one shaft bottom functional layer 40, 86 and support fabric plies 42, 88, respectively, but no additional layers. In the embodiment of Figures 1 and 2, a net band or mesh material, sometimes referred to as a mesh, is omitted.

The greatest occurrence of sweat to be produced and transported by the sole is in particular shaft bottoms 34 and 80 respectively. In addition, under each shaft bottom 34, 80, there are maximum openings in the form of cutouts 12, 60, respectively, so that the likelihood of moisture removal in these places is maximized.

The inventors of the present invention do not need an additional third layer of each shaft bottom functional layer stack 38, 84 or each shaft bottom functional layer stack 38, 84 can be in a two-ply configuration in that region, As a result it has been found that the cost for the third layer can be saved and the amount of sweat that can be carried by omitting the third layer also increases. Omitting the third layer of the shaft bottom functional layer stack eliminates the water vapor barrier that must be overcome by moisture.

Surprisingly, a waterproof connection is possible nonetheless even if no further plies such as a netband are present.

In the shaft device 22 of the first shoe 2 of FIG. 1, this two-ply shaft bottom functional layer stack 38 is arranged directly on the incision 12, in particular from the inside of the shaft device 22. In the shaft arrangement 70 of the second shoe 52 of FIG. 2, which provides effective moisture removal, the two-ply shaft bottom functional layer stack 84 is provided with a sole sole 82 through which additional moisture passes. ).

3 shows a separate cross-sectional view of a portion of a two-ply shaft bottom functional layer stack 38 of the shaft bottom 34 of the shaft device 22 of FIG. 1.

One can see the lower support fabric ply 42 and the relatively somewhat thinner shaft bottom functional layer 40 forming the actual membrane.

4 shows a cross-sectional view of the forefoot area of the third shoe 98 according to a further embodiment of the invention.

The third shoe 98 has the same sole unit 4 and first shoe as the sole unit 4 of the first shoe 2 of FIG. 1, although in contrast the suction member 102 is provided as an additional member. It includes the same shaft device 100 as the shaft device 22 of (2).

Members of the third shoe 98 that coincide with the members of the first shoe 2 are denoted using the same reference numerals.

The suction tape 102 is formed from the space between the outer net band 28 of the shaft functional layer stack 26 and the inner surface of the outer material ply 24 of the shaft device 100 under the support fabric ply 42. Extend outwardly. Suction member 102 comprises a hygroscopic material, such as a cotton, and can attract and transport water in the form of liquid and water vapor.

The suction member 102 illustrated by way of example in FIG. 4 is a support fabric from the space between the shaft functional layer stack 26 and the outer material ply 24 of the bottom section of the vertical section of the shaft region 23. It extends to the area approximately center below ply 42. The suction member 102 may enclose its region in the space between the shaft functional layer stack 26 and the outer material ply 24 on the inner surface of the outer material ply 24, and the outer material ply 24 on the way. It has a curved trajectory and extends past the lasting adhesive 44 to the central region below the shaft bottom functional layer stack 38. The suction member is bonded to its area under the shaft bottom functional layer stack 38 directly on the support fabric ply 42 of the shaft bottom functional layer stack 38, and the suction member is in its interspace. The side section may also be bonded to the shaft functional layer stack 26 or to the outer material ply 24.
