Description

For a long time there have been shoes with a water tight and water vapor permeable toe, so that such shoes, despite being water tight, can give off sweat moisture in the upper zone of the shoe. So that sweat moisture could also evaporate in the sole area, we went over to the sole structure, which has a sole undercarriage with through holes passing through its thickness and above it a water-impermeable and water-permeable functional layer of the sole, for example, in the form of a membrane. An example is shown in EP 0 382 904 A2, in which the undercarriage of the sole has passage holes in the form of microperforations with a corresponding restriction of permeability to water vapor.

To ensure higher permeability to water vapor, taking into account the strong tendency to sweat a person’s legs, we proceeded to supply the undercarriage of the sole with larger passage openings compared to microperforation. From EP 0 275 644 A2, which shows an example of this, the idea of making the passage openings as large as possible is known in order to achieve a particularly high permeability to water vapor.

The larger the passage openings of the undercarriage of the sole, the greater the risk of damage to foreign objects located above the passage of the passage of the sole of the membrane, such as, for example, small stones that penetrate through the passage openings, and thereby violate its impermeability to water. Therefore, in EP 0275644 A2, it is provided that between the undercarriage of the sole with its passage openings and the membrane located above it, a protective layer is made of trellised or felt material, which prevents the penetration of foreign objects through the passage openings of the sole of the sole to the membrane.

Other examples with large passage openings of the undercarriage of the sole, in which the passage openings are closed with a membrane from the passage of water to the interior of the shoe, and under the membrane there is a protective layer which should prevent the penetration of foreign bodies to the membrane, are known from WO 2004/028284 A1 , WO 2006/010578 A1, WO 2007/147421 A1 and WO 2008/003375 A1. In all these cases, on the one side of the membrane, usually the film, a textile back is laminated in the form of thin knitwear. The mesh protective layer located between the membrane and the through holes of the undercarriage of the sole provides some protection against foreign bodies from entering the membrane. To improve the protection of the membrane, another protective layer is located between the membrane and the mesh protective layer, which is, for example, a felt layer. Thus, a double protection is created for the membrane, in which two layers are located one above the other, which have each technical protection function.

The choice of material for these layers, as well as the values of their thickness and strength, must be coordinated with the needs of the corresponding practical embodiment. This applies both to known solutions and to the solutions proposed in this invention.

Another example for very large passage openings is shown in WO 2007/101624 A1, according to which large passage openings of the undercarriage of the sole are stabilized by stabilizing bridges and / or stabilizing gratings. They carry a textile material, such as felt material, which is permeable to water vapor and which enters into the passage openings. The sole running gear complex thus constructed is connected to the top of the shoe, the bottom of the top being covered by a water-impermeable and water vapor-permeable functional layer of the bottom of the shoe, so that the entire shoe is water-impermeable and water-vapor permeable.

A fiber layer that has at least two fiber components that differ with respect to the melting temperature, at least a portion of the first fiber component has a first melting point and below the first softening temperature range, and at least a portion of the second is particularly suitable for textile material the fiber component has a second melting temperature and a second softening temperature range lying below, and a first melting temperature and a first temperature range of softening is higher than the second melting point and the second softening temperature range, and the fiber layer due to thermal activation of the second fiber component using the adhesive softening temperature lying in the second softening temperature range is thermally mechanically hardened while maintaining water vapor permeability in the thermally hardened zone. In this case, you can close either the passage opening or, if necessary, several passage holes of the undercarriage of the sole with separate pieces of textile material, or you can close all the passage holes of the chassis of the sole with one single piece of material.

In this famous shoe, textile material has two functions. On the one hand, it serves to stabilize the sole structure, in particular with respect to the fact that the sole of the sole with large openings cannot provide sufficient stabilization of the sole structure. Namely, the textile material is made, on the one hand, with a relatively high intrinsic stability, which improves the stability of the entire structure of the sole. On the other hand, in a finished shoe, for example, according to WO 2007/101624 A1, there is a water-impermeable, water-vapor-permeable membrane above the sole structure, which is protected by a textile material from damage by foreign objects, such as pebbles, which can damage the membrane.

Suitable textile materials are, in particular, polymers selected, for example, from polyester (PES), polypropylene, polyamide (PA) and a mixture of polymers.

In one embodiment, according to the aforementioned WO 2007/101624 A1, the textile material consists of a fiber connection in the form of thermally hardened and additionally hardened on the surface by heat treatment of the surface of a nonwoven material with two fiber components, each made with polyester fibers. In this case, the first fiber component forms a support component with a higher melting point and the second fiber component with a lower melting point forms a reinforcing component. In order to ensure the temperature stability of the entire fiber joint at least 180 ° C, namely, taking into account that shoes can be subjected to relatively high temperatures during its manufacture, for example, during injection molding of the undercarriage of the sole, in the considered embodiment for both fiber The components used are polyester fibers with a melting point above 180 ° C. There are various versions of polyester polymers which have different melting points and corresponding lower softening points. In the present embodiment of the felt material, a polyester polymer with a melting point of about 230 ° C is selected for the first component, while a polyester polymer with a melting point of about 200 ° C is selected for the second fiber component. The second fiber component may be a fiber with a core and a sheath, wherein the core of this fiber consists of a polyester with a softening temperature of about 230 ° C, and the sheath of this fiber consists of a polyester with a softening temperature of about 200 ° C. Such fiber components with two parts of a fiber with different melting points are also called “Bico”. More detailed information on such textile material can be found in the already mentioned WO 2007/101624 A1.

Particularly suitable for both of the above purposes, namely, stabilization and protection of the membrane, a thermally hardened textile material has the disadvantage that its fiber component serving as a hardening component is poorly and only insufficiently dyed and therefore remains white in the fiber joint, which gives the textile material a generally unfavorable appearance. This is unpleasantly evident because the textile material is visible through the large passage openings of the undercarriage of the sole. Therefore, for the ever-increasing need to complete all shoes, and thus also the lower side of its undercarriage, soles in accordance with the fashion by also giving the lower side of the sole structure the look appropriate to the fashion, in particular due to a pleasant and varied color, this textile material is not suitable.

It is also known to cover large openings in the sole with other materials, for example, a felt-like material, which at least partially consists of aramid fibers, such as KEVLAR. However, aramid fibers are also not or are difficult to dye, so that in this case the above problem arises.

For example, from the already mentioned WO 2006/010578 A1, it is known to cover large openings in the sole with a mesh, for example of nylon. Above this net is a membrane, which on the side facing the net can be connected to a protective layer of felt material. The mesh consists of a loop structure, while due to external contact, in particular, when walking in appropriately made shoes, loops can be separated from the structure, which then hang inside the opening of the undercarriage of the sole. Separated loops and / or drooping fibers are undesirable in terms of appearance and may under some circumstances reduce the safety of shoes.

In addition, instead of a felt-like material, a fabric or knitwear can be used which, on the basis of the fibers used, also has the problem of impossibility of dyeing, in which case individual fibers can also be separated from the fabric structure.

In these cases, the inability to dye the fibers used or small damage to the fiber structure can lead to an unsatisfactory appearance of the material used and thereby the shoes provided with them.

With the help of this invention, a sole assembly for a shoe is created, which provides a satisfactory and wide range of any fashionable implementation of the bottom side of the sole structure regarding coloring and patterning, as well as material selection, without serious deterioration of water vapor permeability of the sole assembly or its barriers, accordingly, protection functions.

This is achieved according to the invention using the plantar assembly according to claim 1, with which a shoe product according to claim 25 can be manufactured according to the invention. Embodiments of the invention are given in the dependent claims.

According to the invention, the sole assembly for a shoe is permeable to water vapor and permeable to water and has at least one sole layer with at least one opening passing through its thickness. In addition, it has at least two superimposed planar layers that cover at least one opening and of which the first planar layer has a textile vapor permeable barrier layer and the second plane layer has a water vapor permeable laminating layer, which is located under the first planar layer and is visible from the bottom side of the sole layer in at least one opening.

In one embodiment, the barrier layer is provided with a fiber layer that has at least two fiber components that differ in their melting points, with at least a portion of the first fiber component having a first melting temperature and a lower softening temperature range lying below and at least a portion of the second fiber component has a second melting point and a second softening temperature range lying below, and a first melting temperature and a first range the softening temperature range is higher than the second melting point and the second softening temperature range. The fiber layer is mechanically thermally hardened due to the thermal activation of the second fiber component with the softening temperature of the adhesive lying in the second range of softening temperatures while maintaining water vapor permeability in the thermally hardened zone.

There may be various reasons for closing shoes with a plantar knot, in particular, of the aforementioned view, visible from the underside of the undercarriage of the sole through openings having a large area, also called openings, of the plantar material, at least partially with a laminating layer according to the invention.

The use according to the invention of such a laminating layer in the plantar assembly with the aforementioned fiber layer is based on the understanding that coloring the fiber component with a lower melting temperature serving as a reinforcing component requires that this fiber component be heated to a temperature that lies above the softening temperature of this fiber component so that this fiber component cannot be dyed. It looks different for other fiber components with a higher melting point. Its melting point lies above the temperature required for dyeing. Therefore, dyeing is possible only with respect to the fiber component with a higher melting point, but not with respect to the fiber component with a lower melting point, so that bright spots cannot be avoided inside the fiber connection of the textile material, which leads to an aesthetically less attractive appearance.

This problem is solved according to the invention in the construction of the soles with such a fiber layer so that they put up with unsatisfactory dyeing of the textile material and before this textile material have a laminating layer, which consists of a material with a favorable color or color, and this material is, for example, grating or mesh or consists of a perforated flat material or textile material with a high permeability to water vapor, which thereby can hardly adversely affect and permeability to water vapor of the plantar node due to the laminating layer. Therefore, with the solution according to the invention, it is possible, with a substantially non-deteriorated water vapor permeability, to hide the less attractive appearance of the textile fiber layer behind the laminating layer, which is not subject to the restrictions on color or dyeing explained above in connection with textile material. Therefore, the laminating layer can be independently dyed and substantially in accordance with almost any fashionable concept, which is not possible for the textile material of the aforementioned fiber layer. For the laminating layer, materials that can be well stained and / or which can be patterned or which can receive attractive colors and / or patterns from the manufacturer can be purposefully applied.

Thus, using the solution according to the invention, it is possible to fulfill a technical requirement, namely a protective function, and an aesthetic requirement, namely, an optically more attractive form, due to the fact that these two requirements are met not with a single layer, but divided into two different layers, of which each in itself can be purposefully made taking into account the special requirements and functions. On the one hand, there is no need for compromises for a layer with a technical function in order to realize at least a tolerable external impression. On the other hand, a layer with an aesthetic function can be performed almost exclusively in accordance with this function, since it does not have to perform the technical function of another layer.

There are other commercial advantages of separating a technical function, for example, a stabilization function, and an aesthetic function. A layer with a technical function, for example, a stabilization layer, can be made with a standard color, so that it can be applied to all shoe products that must be equipped with such a technically effective layer that is very economical. A layer with an aesthetic function, namely a laminating layer, can be selected from the standard assortment, which is also very economical.

The use of a laminating layer according to the invention may also be advantageous when there are materials for both components of the heat-strengthened fiber layer that are not subject to the above color or dye limitation. For example, the thermally hardened textile material of the fiber layer is more expensive than materials that are suitable for the laminating layer. In particular, in the high-fashion sector of the footwear market for free time, there is a strong trend of supplying the same or different shoe models with different colors and different patterns, for example, in order to match different age groups with different fashion designs. If such a requirement were met with differently colored and differently patterned fiber layers, the shoe manufacturer should have and store in the warehouse, respectively, colored and / or correspondingly patterned fiber layers. This would be a disadvantage not only from the point of view of logistics for both the fiber layer manufacturer and the shoe manufacturer, but also from the point of view of the higher price for the shoe manufacturer due to the relatively small number of products of each color and / or pattern. Due to the fact that when applying the laminating layer, the appearance of the bottom side of the plantar node is no longer determined by the material of the fiber layer, but by the type of the laminating layer, the shoe manufacturer can purchase a uniform material of the fiber layer and concentrate on the optical and fashionable appearance of the lower side of the plantar node on the laminating layer. The manufacturer of the shoes is the material for this, or if he does not make the undercarriage of the sole for his shoes, the manufacturer of the sole can purchase purposefully in quantity and color, as well as the structure and type of material, or he can make them with respect to color and pattern, while he can procure materials from a larger number of suppliers for the desired capturing layers, so that he can contact different material manufacturers both in terms of price and the possibility of obtaining different materials. Thus, regardless of whether it is possible to color the fiber layer material in accordance with the manufacturer’s ideas or not, it may be desirable to optically shape the bottom side of the plantar assembly with respect to color and pattern using an additional laminating layer, in particular for the above logistics considerations, diversity and value.

If the material of the lamination layer must be painted after its manufacture, for example, by spraying, screen printing or the like, it is only necessary to ensure that the painting or patterning is performed so that the loops or other holes or pores of the material of the lamination layer remain open so that the desired water vapor permeability is maintained. Such a color design with such means and methods would not be possible with a textile layer, in particular, a felt layer, which in known cases is visible through the through holes of the undercarriage of the sole. On the one hand, on the surfaces of textile materials, such as felt, it is impossible to obtain colored patterns, in particular for fine structures, with sufficient resolution. On the other hand, it is only difficult to prevent substantially clogging of the surfaces of such materials when ink is applied by spraying or screen printing, so that the desired water vapor permeability can no longer be realized. In addition, such technologies are relatively expensive. The embossing of textile materials leads to an uneven surface height, which is also a disadvantage when casting the material of the running gear of the sole, since the spreading of the material of the running gear of the sole in the textile layer becomes unpredictable.

A cushion layer according to the invention is particularly preferred in an embodiment in which the fiber layer has two fiber components and a material is used for the second fiber component in which the softening temperature range of the second fiber component is lower than the temperature required to color the second fiber component. Namely, in this case, the aesthetically unattractive appearance of the fiber layer with its white spots can be lapped only with the help of the laminating layer according to the invention, so that the bottom side of the plantar node receives an optically attractive appearance.

In particular, in the case where the shoes with the sole unit, which is provided with a laminating layer according to the invention, are intended for young buyers, the “metallic appearance” achieved by the laminating layer can be attractive. Therefore, in one embodiment of the invention, the laminating layer consists of a material that provides a metallic appearance. In the first embodiment of the invention provided for this, the material of the laminating layer consists solely of metal, for example of a metal grid or metal mesh. In the second embodiment of the invention provided for this, the material of the laminating layer consists of a metallized plastic lattice or is made with a metallized fiber, which is inserted into the yarn structure or is applied in the form of a yarn net.

Examples of material for a purely metal laminating layer are iron, aluminum and steel. Examples of a coating material for a metallized plastic layer are fabrics, knitwear and weaves with sheaths made of tin, silver, copper, nickel or other alloys, for example POLYMET® from Platingtech Beschichtung GmbH & Co. KG, Nicklasdorf, Austria. Thus, the material becomes tensile, resistant to wear and corrosion. Examples of material for a metallized plastic fiber component are polyester, polypropylene, polyurethane, polymers, polyamide, for example, Mesh Silver polyamide from Panatex, 25030 Zocco d / Erbusco, Italy.

However, as the material for the coating layer, water vapor permeable due to processing, such as, for example, perforation, materials or perforated flat material, for example, polyamide, polyurethane, etc., or initially water vapor permeable, are also suitable. material, for example, from plastic, textile, metal, leather, fiberglass, or a combination thereof.

The above examples of material for the coating layer can also be combined with each other or with other materials in order to achieve the desired color or pattern.

In one embodiment of the invention, the laminating layer 'has a substrate and a coating covering the surface of the substrate, the coating being made with a material that is colored or has at least one coloring material. Due to this, it is possible to combine various requirements for the material for the laminating layer, for example, a substrate with the desired mechanical properties and the desired water vapor permeability in combination with a coating that can be painted or patterned solely from an aesthetic point of view, since it should not bring anything into the desired or required mechanical properties or the desired water vapor permeability of the coating layer.

In one embodiment of the invention, the laminating layer is made with a dirt-repellent material.

In the case when the laminating layer is made with a mesh, lattice or loop material, for example, textile material, the laminating layer can be made with monofilaments or with filament yarns.

Filament yarns are composed of several fibers, between which there are capillary zones. Contaminants, such as, in particular, dirt, contaminated liquids, such as, for example, dirty water, or pollutant liquids, such as, for example, oils, which can hardly be removed from the yarn, can penetrate into them, so that the yarn and with it, the laminating layer for a long time and irretrievably looks dirty or at least optically untidy.

In one embodiment, this is prevented by the fact that the laminating layer is made using monofilaments that do not have capillary channels. In one particularly preferred embodiment of this type, monofilament uses a fiber material that is not absorbent, such as a plastic material.

In one embodiment of the invention, in which the laminating layer is made with yarn, i.e. with filament formation, the deposition of contaminants is prevented by the fact that the yarn is surrounded by a sheath of plastic, such as, for example, silicone or a substantially colorless silicone-like material, so that the mesh openings, respectively, of the lattice of this laminating layer remain open and therefore water permeability is maintained couple. Based on the supply of yarn to this sheath, such contaminants cannot penetrate between the yarn-forming fibers. Due to this, barely eliminating and thereby remaining contamination of the coating layer is prevented. On the other hand, by supplying a sheath with such substantially colorless materials, the color of the yarn and thereby the lamination layer is visible.

In another embodiment, the capillary zones of the multifilament yarn are at least partially filled or impregnated with plastic. This eliminates the penetration of dirt into the capillary zones and prevents the remaining contamination of the coating layer.

In one embodiment of the invention, the laminating layer is connected to the barrier layer only in the edge zones so that, in particular, when walking, it is possible to relatively move the laminating layer relative to the barrier layer. This means that wherever the laminating layer is located above the large opening of the lower layer of the sole, in particular the undercarriage of the sole (and is visible through this large opening), the laminating layer is not connected to the barrier layer, which allows relative moving the laminating layer relative to the barrier layer at least in the zones of this large opening area. Contaminants, such as, in particular, dried sludge or the like, which can be fixed in the openings of the grate or mesh, can be loosened and separated due to relative movement, so that they fall off and the laminating layer remains clean. This relative dirt-separating dirt can also be caused by the fact that the sole structure of the shoe removed from the foot can be bent by hand, for example, when the dirt sits so firmly that it is not sufficiently separated from the lining layer due to walking movements.

In one embodiment of the invention, the laminating layer is connected to the barrier layer only in the peripheral marginal zones. For the case where the barrier layer is provided with one or more stabilizing jumpers, the laminating layer can also be or additionally connected to the barrier layer in the zone of the stabilizing jumpers. It is only important that the laminating layer remains unconnected with the barrier layer where at least one opening of the sole layer, for example, the undercarriage of the sole, is located, so that there is a possibility of dirt separating the relative movement of the laminating layer relative to the barrier layer.

In one embodiment, the two measures described above are combined to keep the laminating layer clean. In this embodiment, the laminating layer, on the one hand, is connected to the barrier layer only in the marginal zones, in order to enable said relative movement, which helps to separate and fall off the dirt that has fixed in the openings of the laminating layer. On the other hand, in this embodiment, the laminating layer is made with either a monofilament material or with a yarn that is surrounded by a sheath or impregnated with silicone or a similar silicone material, so that contaminants cannot penetrate the yarn and the yarn remains clean and with its original color. In this embodiment, the dirt can only penetrate into the openings of the laminating layer in the form of a mesh or lattice, where, due to the indicated relative movement between the laminating layer and the barrier layer, it separates again and can fall out, so that the laminating layer is again clean and has its original optical view.

The separation of dirt from the openings of the coating layer is particularly effective and thorough in the embodiment in which, in addition to the above measures, a barrier layer is applied, which is at least on its side facing the coating layer and is relatively smooth, for example, because it consists made of fiber material that can be smoothed out and provided with a continuous surface using heat treatment. When using such a barrier layer, dirt settles almost only in the openings of the laminating layer, since it does not adhere to the smooth, continuous surface of the barrier layer. In this embodiment, which is made with a combination of a barrier layer with a smooth surface and a laminating layer, which, on the one hand, is connected to the barrier layer only in the edge zones and, on the other hand, is made with a monofilament material or with yarn that is surrounded by a sheath or impregnated with silicone or a silicone-like material, a particularly effective and thorough cleanliness of the laminating layer is achieved, thereby preserving the optical appearance of the laminating layer and the underside of the sole structure o UWI.

In one embodiment of the invention, the laminating layer is made of leather made with the repulsion of water, oil and dirt, in order to prevent the penetration of contaminants into the skin structure and thereby adversely affect the optical appearance of this laminating layer. Suitable materials for this purpose are, for example, fluorocarbons, in particular in the form of resins of fluorocarbons containing silicone agents and the like. In this embodiment, the skin serving as a laminating layer is also preferably connected to the barrier layer only in its end zones, in order to ensure the possibility of the above relative movement of the laminating layer and the barrier layer and thereby causing the dried mud to fall away from the laminating layer.

In embodiments of the invention, the laminating layer may have water vapor permeability in the range of 10,000 g / m ² in 24 hours to 50,000 g / m ² in 24 hours, in particular in the range of 20,000 g / m ² in 24 hours to 30,000 g / m ² in 24 hours. In one embodiment, the laminating layer has a water vapor permeability of 26,000 g / m ² at 24 hours. In embodiments of the invention, the stabilizing layer, referred to herein as the barrier layer or fiber layer (textile material), may have water vapor permeability in the range from 3,000 g / m ² in 24 hours to 20,000 g / m ² in 24 hours, in particular in a range from 8,000 g / m ² in 24 hours to 15,000 g / m ² in 24 hours. In one embodiment of the invention, the stabilizing layer has a water vapor permeability of 12.588 g / m ² at 24 hours. By using these water vapor permeabilities of the laminating layer and the stabilizing layer, the desired water vapor permeability for the entire plantar node can be achieved.

In embodiments of the invention, the entire plantar assembly may have water vapor permeability in the range from 1,000 g / m ² in 24 hours to 20,000 g / m ² in 24 hours, in particular in the range from 6,000 g / m ² in 24 hours to 12,000 g / m ² in 24 hours. In one embodiment, the water vapor permeability of the entire plantar assembly is 9.337 g / m ² at 24 hours.

In one embodiment of the invention, the sole layer of the sole assembly, to which the lining layer is matched, consists of a die-castable material, in particular a plastic material. This enables another embodiment of the invention in which the sole layer is injection molded onto the fiber layer and the laminating layer so that the fiber layer and the laminating layer are connected through the material of the sole layer to the sole layer. In one embodiment, the fiber layer and the laminating layer can be connected to each other using the sole layer material.

In one embodiment, the fiber layer and the laminating layer can be penetrated by the sole layer material. These embodiments provide the possibility of a particularly preferred, since inexpensive and technically low cost, connection of the sole layer, the fiber layer and the laminating layer.

In one embodiment of the invention, the sole layer forms the undercarriage of the sole. In another embodiment, the sole layer forms an intermediate sole of the sole assembly.

In one embodiment, the fiber layer and the laminating layer form an insert. This makes it possible to use for the sole designs of the same type, which have, for example, the same undercarriage of the sole, respectively, the midsole and / or other identical components, due to their combination with variously made inserts that differ from each other, in particular with its laminating layer, of a relatively large number of plantar nodes, according to the invention, in a rational and thereby economical manner and in compliance with the preferred conditions from the point of view of logistics.

In addition, the invention makes it possible to create a shoe product with a plantar assembly, which is provided with a lining layer according to the invention, and a shoe product, which is provided with a water-impermeable and water vapor-permeable functional bottom layer in the end zone of the shoe upper located on the side of the sole of the shoe. the top of the shoe, while provided with a functional layer of the bottom of the top of the shoe, the sole assembly is fixed to the end zone of the top of the shoe so that ny layer shoe shaft bottom, at least in the region of at least one opening connected to the fiber bed. The latter provides a particularly high permeability to water vapor, since there is no glue in the area of the opening (s) between the fiber layer and the functional layer of the bottom bottom of the shoe, which would lead to a decrease in water vapor permeability.

In one embodiment of the invention, the shoe has, along with the functional layer of the bottom of the shoe, a functional layer of the upper of the shoe that extends over water or is connected opaque to the functional layer of the bottom of the shoe and extends to form a sock-like insert (also called liner).

Such a shoe is, on the one hand, (with the exception of the hole for introducing the foot) on all sides impervious to water and yet permeable to water vapor, and provides, on the other hand, the possibility of any execution relative to the type of bottom side of the sole of the shoe, which is important, in particular, for fashionable shoes for aesthetic reasons and for the recognition of the manufacturer by the appearance of the bottom side of the sole.

Sole undercarriage:

undercarriage of the sole means that part of the sole that is in contact with the ground / base, respectively, forms the main contact with the ground / base. The undercarriage of the sole has at least one working surface in contact with the ground.

Midsole:

in the case where the undercarriage of the sole is not directly applied to the upper system of the shoe, an intermediate sole may be introduced between the undercarriage of the sole and the upper system of the shoe. The midsole may serve, for example, for upholstery, damping or as a filler material.

Liner:

a liner is a sock-shaped inner lining of the upper system of a shoe. The liner forms a blind lining of the upper system of the shoe, which essentially completely covers the interior of the shoe.

If, instead of the functional layer of the liner, the functional upper layer of the shoe and the lateral functional layer of the bottom of the upper of the shoe are used, they are sealed from each other impervious to water, for example, in the lower zone of the upper system of the shoe located on the sole side. The functional layer of the bottom bottom of the shoe and the functional layer of the top of the shoe can be made of different or the same material.

Suitable materials for a water-impermeable, water-vapor permeable functional layer are, in particular, polyurethane, polypropylene and esters, including polyesters and their laminates, as described in US-A-4 725 418 and US-A-4 493 870 In one embodiment, the functional layer is made of microporous, elongated polyurethane fluoroethylene (ePTFE), as indicated, for example, in US-A-3 953 566 and US-A-4 187 390. In one embodiment, the functional layer is made of elongated polytetrafluoroethylene which is equipped with a hydro philic impregnating agents and / or hydrophilic layers; see, for example, US-A-4 194 041. By microporous functional layer is meant a functional layer with an average effective pore size of about 0.2-0.3 microns.

Laminate:

A laminate is a joint made up of several layers that are firmly bonded to each other, usually by gluing or welding together. In the laminate of the functional layer, there is provided a water impermeable and / or water vapor permeable functional layer with at least one textile layer. At least one textile layer serves primarily to protect the functional layer during processing. This is called a two-layer laminate. The three-layer laminate consists of a water-impermeable, water-vapor-permeable functional layer, which is embedded in two layers of textile. The connection between the functional layer and at least one textile layer is, for example, by means of a continuous water vapor permeable adhesive layer or by an intermittent layer of water vapor impermeable adhesive. In one embodiment, between the functional layer and one or both layers of textile, the adhesive can be applied as a dot pattern. A point, respectively, intermittent application of glue is used, since a layer of a water-impermeable adhesive covering the entire surface would block the water vapor permeability of the functional layer.

Barrier layer:

the barrier layer serves as a barrier against the penetration of substances, in particular in the form of particles or foreign bodies, for example pebbles, to the material layer to be protected, in particular to the mechanically sensitive functional layer or to the membrane of the functional layer.

Cache layer:

the laminating layer is a material layer provided for aesthetic reasons, the function of which is laminating the appearance of a layer that is visible without a laminating layer, but covered with a laminating layer and provided, in particular, due to its technical function, the material layer, in particular when the material layer is not favorable or not desired aesthetically pleasing appearance.

Porous:

in connection with the coating layer according to the invention, porous means here that the material of the coating layer is initially or due to treatment permeable to water and permeable to water vapor.

Puncture resistant:

the puncturing strength of a textile flat formation can be measured using the measurement method used at the Swiss Materials Research Institute (EMRA) using an Instron tensile tester (model 4465). Using a stamp, a round piece of textile with a diameter of 13 cm is cut down and fixed on a support plate, in which there are 17 holes. The punch, on which 17 needle-shaped spikes (sewing needles of type 110/18) are fixed, is lowered down at a speed of 1000 mm / min so that the needles are immersed into the holes of the base plate through a piece of textile. The force for piercing a piece of textile is measured using a measuring sensor (force sensor). The result is determined by three samples.

The piercing strength of a material layer, such as a barrier layer or a stabilizing layer, is determined using the test method "TM 37 SATRA" technology center SANTRA Technology Center, Wyndham Way, Kettering, Northamptonshire, NN 16 8SD, UK.

Founding document:

European standard EN 344-1, in particular section 4.3.3 (penetration resistance).

Test Description:

the force required to pierce a hardened steel needle with a sharp top at the bottom of the shoe or boot is determined.

Test device parameters:

Instron Deutschland GmbH, Werner-von-Siemens-Strasse 2, 64319 Pfungstadt;

a steel needle equipped with a sharp apex with a diameter of 4.5 mm and an angle at the apex of 30 ° serves as an anvil;

feed rate 10 ± 3 mm / min;

Test Locations:

Test TM 37 SATRA provides for testing the piercing strength of the sole four test sites that are distributed along the sole and have a distance of 20 mm from each other (inner foot, outer foot, midfoot, heel). Since in connection with this invention we are talking about the piercing strength of the barrier layer, for which, however, the danger is the penetration of sharp particles directly only in the area provided for the permeability of water vapor having a large area of the openings of the provided sole layer, for those embodiments of the invention, which such openings are not provided in the heel area, when applying the TM 37 SATRA test, the test sites in the heel area are omitted.

Determination of piercing strength:

in connection with this invention, piercing resistance means that the test material, in particular the shoe-stabilizing material of the invention, or the barrier material, withstands a force of at least 40 N when tested for piercing by the TM 37 SATRA method.

Thickness:

the thickness of the material stabilizing the shoes is tested in accordance with DIN ISO 5084 (10/1996).

Water tight:

the functional layer / laminate of the functional layer / membrane is considered impervious to water, if necessary including the joints provided in the functional layer / laminate of the functional layer / membrane when they provide a water inlet pressure of at least 1 × 10 ⁴ Pa. Preferably, the material of the functional layer withstands a water inlet pressure of greater than 1 × 10 ⁵ Pa. In this case, the water inlet pressure should be measured using a method in which distilled water at a temperature of 20 ± 2 ° C is supplied to a sample of a functional layer with an area of 100 cm ² with increasing pressure. The increase in water pressure is 60 ± 3 cm of water per minute. The water inlet pressure corresponds to the pressure at which water first appears on the other side of the sample. A detailed description of the method is given in ISO-Norm 0811 for 1981.

The water tightness of a shoe can be checked, for example, using a centrifuge system of the kind specified in US-A-5 329 807.

Permeability to water vapor:

the functional layer / laminate of the functional layer is considered as water vapor permeable if they have a water vapor permeability ret coefficient of less than 150 m ² × Pa × W ⁻¹ . Water vapor permeability is determined according to the Hohenstein-Hout model. A description of this method is given in DIN EN 31092 (02/94), respectively, ISO 11092 (1993).

The permeability values for the water vapor of the barrier layer, fiber layer, stabilizing layer / laminating layer are determined using the so-called Becher method in accordance with DINEN ISO 15496 (09/2004) [A3].

The water vapor permeability value of the sole [A4] can be measured using the measurement method specified in EP 0 396 716 B1, which is designed to measure the water vapor permeability of the entire shoe. To measure the water vapor permeability of only the sole unit of the shoe, the measurement method according to EP 0 396 716 B1 can also be used by measuring using the measuring device shown in FIG. 1 of EP 0 396 716 B1 in two consecutive measurement scenarios, and namely, once a shoe with a water-permeable sole assembly and another time an otherwise identical shoe with a water-permeable sole assembly. From the difference between the two measurement values, it is possible to determine the percentage of water vapor permeability, which is determined by the water vapor permeability of the plantar permeable to water vapor.

In each measurement scenario, the measurement method according to the invention, EP 0396716 B1, is performed, namely with the following sequence of steps:

1. Conditioning of the shoe by keeping it in an air-conditioned room (23 ° C, 50% relative humidity) for at least 12 hours.

2. Removal of the insole.

3. Cladding of a shoe product with a water vapor-permeable lining material that can be sealed in the area of the foot opening and is impervious to water and impervious to water vapor, an airtight seal, and a watertight seal (for example, made of Plexiglass and with an inflated cuff).

4. Filling the facing material with water and closing the opening for entering the foot of the shoe using a sealing plug.

5. Pre-conditioning of a shoe filled with water by leaving it at rest for a predetermined period of time (3 hours), while the water temperature is kept constant at 35 ° C. The climate of the surrounding space is also kept constant with a temperature of 23 ° C and 50% relative humidity. During the test, the shoe is blown from the front by a fan with an average wind speed of at least 2-3 m / s (to destroy the stationary layer of air formed around the shoe, which causes significant resistance to water vapor transmission).

6. Weighing the shoe closed with a sealing stopper filled with water after pre-conditioning (to obtain m2 in grams).

7. Leaving again at rest and actually the test phase for 3 hours under the same conditions as in stage e.

8. Weighing again closed, water-filled shoe after the test phase for 3 hours (to obtain a weight of m3 in grams).

9. Determination of water vapor permeability of the shoe from the shoe leaving the shoe during the test for 3 hours, the amount of water vapor (m2-m3), in grams in accordance with the formula M = (m2-m3) in g / 3 h.

After performing both measurement scenarios, in which the values of water vapor permeability were measured, on the one hand, for the entire shoe with the water-permeable sole assembly (value A) and, on the other hand, for the entire shoe with the water vapor impermeable structure bottom of the shoe (value B), it is possible to determine the value of water vapor permeability for only the sole assembly permeable to water vapor from the difference AB.

When measuring the water vapor permeability of a shoe with a water vapor permeable sole assembly, it is important to avoid that the shoe or its sole is directly on the covered bed. This can be achieved by lifting the shoe or installing the shoe on the lattice structure, so that the ventilation airflow can also pass completely or completely under the undercarriage of the sole.

It is advisable to carry out repeated tests at each test of a shoe product and consider their average value, in order to provide a better opportunity to assess the measurement spread. At least two measurements must be performed with a measuring device for each shoe. For all measurements, it is necessary to proceed from the natural deviations of the measurement results of ± 0.2 g / h around the actual value, for example, 1 g / h. Thus, in this example, for an identical shoe, measurement values between 0.8 g / h and 1.2 g / h can be obtained. Influence factors for these deviations may come, for example, from the person conducting the test or from the quality of the seal on the upper edge of the top of the shoe. By averaging several individual measurement results for the same shoe, a more accurate representation of the actual value can be obtained.

All water vapor permeability values of the sole of the knot are based on a normally laced men's shoe of size 43 (French measure), although this indication of size is not standardized and shoe products of different manufacturers may differ from each other.

The following is a further explanation of the invention based on exemplary embodiments that are merely non-restrictive examples for carrying out the invention, with reference to the accompanying drawings, in which:

figure 1 is an embodiment of a shoe with a shoe top and a sole complex of a shoe with a plantar assembly made according to the invention, in isometric view;

figure 2 - shoe product according to figure 1, while the sole complex of the shoe is not yet connected to the top of the shoe, in an isometric view;

figure 3 - the complex sole of the shoe according to figures 1 and 2, in an isometric view from above;

Fig. 4 is a cross-sectional view of the shoe product shown in Fig. 1 in an embodiment with a glued sole complex of the shoe product at the installation stage, according to Fig. 2, while the top of the shoe product is not shown completely; and

Fig. 5 is a cross-sectional view of a shoe product according to Fig. 4, but in an embodiment of a shoe product with a molded sole complex of the shoe product, the top of the shoe product is also not completely shown.

If concepts are applied here, such as at the top, bottom, right, left, etc., then this always applies to a special image in the corresponding figure and does not have absolute value.

Figures 1 and 2 show in oblique isometric view from below an example of a shoe product 11 according to the invention, with a shoe top 13 and a sole assembly 15 according to the invention. Figure 1 shows a shoe product 11, in which the top 13 of the shoe and the sole assembly 15 are connected to each other. Figure 2 shows a shoe product 11, according to figure 1, at the installation stage before fixing the sole assembly 15 on top of the shoe 13.

The shoe 11 has a forefoot zone 17, a midfoot zone 19, a zone 21 of the heel, and an opening 23 for introducing a foot. The plantar assembly 15 has a sole layer in the form of a carrier layer 25, which is crucial for stabilizing the plantar assembly 15 and which has large openings 27 (see FIG. 2) in the forefoot area 17 and the midfoot area 19. Owing to its stabilizing effect, the carrier layer 27 is also called here the stabilizing layer. A large area in this regard means that the individual openings 27 have an area in the range from one to several square centimeters, for example, in the range from about 2 cm ² to about 30 cm ² , within this range, for example, in the range from 10 cm ² to 20 cm ² . The openings 27 are selected as large as possible in order to create a plantar assembly 15 with the greatest possible permeability to water vapor.

Under the carrier layer 25 is the sole undercarriage 29, which is composed of several separate parts of the sole undercarriage, namely, the sole undercarriage part 29a in the heel area 29a, the sole undercarriage part 29b in the foot pad area and the sole undercarriage part 29c in the area toes. These parts of the undercarriage of the sole are fixed on the lower side of the carrier layer 25. In the area of the foot pad and in the area of the toes, the parts of the chassis of the sole 29b and 29c have openings 27 of a large area that are sized so that the openings 27 of the carrier layer 25 are fully or essentially remain free from the material of the running gear of the sole, so as not to limit the water vapor permeability of the sole assembly achieved by the openings 27 of the carrier layer 25.

In the shown embodiment, over the carrier layer 25 there is a damping layer 31 of the sole, which provides damping of the attack and thereby increases the comfort of the shoe when walking. The damping sole layer 31 has a damping part 4131a in the heel area and a damping sole part 4131b in the forefoot area. The damping portions 4131a and 4131b also have large openings that completely or at least substantially open the openings 27 of the carrier layer 25 so as not to limit or substantially limit the water vapor permeability achieved by the openings 27 of the carrier layer 25.

In one embodiment, the sole may also be formed in one piece. That is, the damping layer and the sole layer are combined into a single undercarriage of the sole, while the material that is best suited to these both properties is selected with respect to the properties of the damping of the offensive and the properties when running.

Not only the damping layer 31 of the sole, but also the parts of the undercarriage 29 of the sole consist of an elastic material with a certain degree of softness, in order to achieve good walking comfort and obtain the undercarriage of the sole with good offensive properties. Based on this relatively soft elastic material and on the basis of folding from separate parts with large openings, the undercarriage - 29 of the sole cannot provide sufficient stability for the entire plantar assembly 15. Even in versions with the one-part undercarriage, the sole is not achieved on the basis of the soft elastic material and large openings quite satisfactory stability of the entire plantar site.

On the basis of its relatively soft material and its openings having a large area, on the one hand, and folding out of separate parts, on the other hand, neither part of the undercarriage 29 of the sole, nor part of the damping layer 31 of the sole provide the stability desired for the sole. Therefore, a carrier layer 25 acting as a stabilizing layer is provided, which can be made of a relatively rigid material, since it should have neither the damping properties of the attack, nor the properties of the undercarriage of the sole. To improve the stabilizing properties of the stabilizing layer 25, which, in spite of its relatively rigid material, can be weakened to a certain extent by openings 27 with a large area, the individual openings 27 of the carrier layer 25 are blocked by stabilizing jumpers 33. Thus, the carrier layer 25 obtains a certain degree of strength bending and twisting, which provides for the entire plantar node 15 the desired stability.

As shown in FIG. 2, the lower end of the top 13 of the shoe is closed by the bottom 35 of the top of the shoe before connecting the sole assembly 15 to the top 13 of the shoe. The bottom 35 of the top of the shoe is provided with a functional layer 37 of the bottom of the top of the shoe, as will be explained below with reference to figures 4 and 5. This functional layer 37 of the bottom of the top of the shoe has, for example, a membrane that is at least impermeable to water, preferably also permeable to water vapor.

While in FIG. 2, the sole assembly 15 is shown in oblique isometric view from below, in FIG. 3, the sole assembly 15 is shown in oblique isometric view from above. As shown in FIG. 3, on the opposite undercarriage of the sole 29, the upper side of the carrier layer 25 in its midfoot 25b and in its forefoot 25, there are several pieces 39a, 39b, 39c and 39d of the barrier layer made in the form of a fiber layer 39. Using these pieces 39a, 39b and 39c of the fiber layer, the openings 27 of the carrier layer 25 are invisible in FIG. 3. FIG. 3 also shows the sole assembly 15 located in the heel zone and in the front foot zone on the upper side of the carrier layer 25 of part 4131a, respectively, 4131b layer damping offensive. The offensive damping layer part 4131a is made in the shown embodiment in the heel area with a substantially continuous surface, while the anterior damping layer part 4131b is provided with recesses where the pieces 39b, 39c and 39d of the fiber layer are located. Pieces 39a-39d of the fiber layer lie above the stabilizing bridges 33, which are not visible in FIG. In the embodiment shown in FIG. 3, the carrier layer 25 has bounding edges 43a, 43b and 43c that surround each respective opening 27 of the carrier layer 25 and which each serve as a frame for a corresponding piece of fiber layer.

Since the parts of the undercarriage 29 of the sole, the carrier layer 25, and the parts 4131a and 4131b of the offensive damping layer have different functions inside the shoe sole complex forming the sole assembly 15, they are also advantageously made with different materials. Parts of the undercarriage of the sole, which have good abrasion resistance and should ensure reliable offensive, for example, consist of thermoplastic polyurethane (TPU) or rubber suitable as the undercarriage of the sole 40. The portions 4131a and 4131b of the offensive damping layer, which should provide shock damping for the user of the shoe while walking, consist of a corresponding elastic flexible material, for example, ethylene vinyl acetate (EVA) or polyurethane (PU). The stabilizing layer 25, which serves as a carrier for the sole undercarriage parts 29a, 29b, 29c not connected to each other and also the offensive damping layer parts 4131a, 4131b and the whole plantar assembly 15, also not connected to each other, 15 as a stabilizing element and must have appropriate elastic stiffness, consists, for example, of at least one thermoplastic.

The fiber layer pieces 39a, 39b, 39c and 39d serve, on the one hand, as mechanical protection for the functional layer 37 of the bottom of the shoe, which is provided with the bottom 35 of the top of the shoe. Small particles, such as, for example, pebbles, which pass through the openings 27 of the carrier layer 25 and penetrate to the functional layer 37 of the bottom of the shoe and can be damaged, are delayed to protect the functional layer 37 of the bottom of the shoe with pieces of fiber layer. In one embodiment of the shoe according to the invention, the fiber bed pieces 39a, 39b, 39c and 39d have an additional stabilizing function. For this purpose, the pieces 39a, 39b, 39c and 39d of the fiber layer consist of a thermally hardened fiber material of the indicated type with at least two fiber components with different melting points and, accordingly, different softening points. By choosing the ratio of the proportions of both fiber components having different melting points and by the degree of heating and thereby softening of the second fiber component, it is possible to exert the desired effect, on the one hand, on the thermal hardening and, on the other hand, on the water vapor permeability of the fiber layer. Based on its thermal hardening, the fiber layer 39, respectively, the pieces 39a, 39b, 39c and 39a of the fiber layer, can serve as stabilizing elements for the plantar site 15.

The fiber layer 39 as such is already known from WO 2007/101624 A1. Therefore, other details regarding the fiber layer 39, which consists of pieces 39a, 39b, 39c and 39d of the fiber layer, namely, both regarding the choice of material and composition of the material, and regarding the manufacture and thermal activation are not specified in detail here and can be gleaned from WO 2007/101 624 A1. The same applies to details regarding the undercarriage 29 of the sole damping the onset of layer 31 and the carrier layer 25, for example, regarding the design, shape and materials used, which can also be gleaned from WO 2007/101624 A1.

As already mentioned above, the fiber layer material used in practical embodiments has the disadvantage that the material used for the second fiber component with a lower melting point cannot be dyed, since dyeing requires temperatures that are higher than the melting temperature of this fiber component. Therefore, with this material of the fiber layer, it is possible at best to dye the fiber component with a higher melting point, while the second fiber component with a lower melting point remains white. Therefore, as also mentioned above, there are very narrow limits for the possibility of optical and aesthetic design of the fiber layer.

This problem is eliminated by means of the laminating layer 45 according to the invention, which is shown in FIGS. 1 and 2 in the form of a lattice visible in the openings 27, and in FIGS. 4 and 5 is represented by a series of square points. In the embodiment of the plantar assembly 15 shown in FIGS. 1 and 2, several pieces of the lining layer 45 are provided, which are aligned with each of the openings 27 of the stabilizing layer 25 and each have a size of the corresponding opening 27, in accordance with the pieces 39a, 39b shown in FIG. 39c and 39d of the fiber layer. Thus, the lower side of each of these pieces 39a, 39b, 39c and 39d of the fiber layer that is visible through the respective openings 27 is cached with the corresponding piece of the laminating layer and is thus not visible. Since almost any materials can be used for the laminating layer 45, if they are, on the one hand, colored or allow coloring and, on the other hand, are water vapor permeable, there is almost no limit to the color and patterning of the laminating layer 45.

FIGS. 4 and 5 show in cross section two embodiments of shoes according to the invention, at the manufacturing stage according to FIG. 2, namely, FIG. 4 shows shoes with a sole assembly 15 adhered to the shoe top 13, and FIG. 15 - shoes with molded sole assembly 15 on the upper 13 of the shoe 15. The cross-section, for example, of the front foot zone of the top 13 of the shoe 11 is shown in a very schematic and not necessarily on a scale scale. Moreover, from the top 13 of the shoe only the bottom 35 of the shoe is shown of the product, while the right side of the upper part of the shoe is not shown mirror symmetrically corresponds to the shown part of the top of the shoe.

In both embodiments shown in FIGS. 4 and 5, the top 13 of the shoe has a front material layer 47, a functional layer 49 of the top of the shoe and the lining layer 51. In both embodiments, the bottom end 55 located on the side of the sole is closed by a multi-layer bottom 35 of the top of the shoe, which has a functional layer 37 of the bottom of the shoe. In both embodiments, the functional layer 49 of the top of the shoe and the functional layer 37 of the bottom of the top of the shoe are connected to each other impervious to water, which leads to the creation of water-impermeable on all sides and when using not only impervious to water, but also permeable to water a functional layer pair on all sides of a shoe product permeable to water vapor. And in both embodiments, the sole assembly 15 has the components already mentioned in connection with FIGS. 1-3, namely, the undercarriage of the sole 29 and the carrier layer 25. In both cases, the large openings 27 that pass through the sole layers are closed fiber layer 39, under which there is a laminating layer 45.

The two embodiments shown in FIGS. 4 and 5 differ with respect to the layers of the sole assembly 15, the design of the bottom 35 of the top of the shoe, the type of fastening of the sole assembly 15 on the top 13 of the shoe and the type of seal between the functional layer 49 of the top of the shoe and the functional layer 37 of the bottom of the top shoe products.

In the embodiment shown in FIG. 4, the sole assembly 15 has, in addition to the sole of the sole 29 and the support layer 25, an attack damping layer 31, and the bottom 35 of the shoe has a mounting sole 53, often called an insole, which is connected to the lower side of the sole the end 55 of the top of the shoe with the expansion joint 57. Under the mounting sole 53 there is a laminate 59 of the functional layer of the bottom of the top of the shoe, in the shown embodiment a three-layer laminate that has a functional layer 37 shaft bottom shoe, embedded between the lower carrier layer of the functional layer 61 and the upper carrier layer 63 of the functional layer. Both carrier layers 61 and 63 of the functional layer consist, for example, each of the textile layer. The upper textile layer 63 is designed so that liquid sealing material 65 can pass through it, which is located between the lower side of the bottom end of the upper layer of the shoe layer 49 and the upper side of the circumferential edge of the bottom layer of the shoe 37, in order to create a water-tight seal between the functional layer 49 of the top of the shoe and the functional layer 37 of the bottom of the shoe. As shown in FIG. 4, the bottom end located on the sole side of the shoe upper material 47 is bent away from the shoe end located on the bottom side of the bottom end functional layer 49 and is glued to the bottom side of the functional bottom layer laminate 59 with the sole adhesive 67 shoe products. The sole assembly 15 is prefabricated and secured with glue 67 for the sole, which is applied to at least the upper side of the circumferential marginal zone of the sole assembly 15, on the lower end 55 of the shoe upper side facing the sole.

In the embodiment shown in FIG. 5, with the sole assembly 15 pushed to the top 13 of the shoe, the sole assembly 15 does not have a damping layer 31. The bottom 35 of the top of the shoe is formed by a mounting sole laminate 69, which is also a three-layer laminate, the outer layer of which , in the shown embodiment, the upper outer layer 63 consists of such a stable and durable material that this laminate 69 of the mounting sole can function as the mounting sole or insole for closing the lower end and 55 top of the shoe. In this embodiment, the functional layer 49 of the upper part of the shoe and the lining 51 of the upper part of the shoe have a protrusion above the front material 47 of the upper part of the shoe. This protrusion is covered by a mesh tape 71, which is permeable to liquid when molding the material of the undercarriage of the sole. The mesh tape 71 is connected on one side only with the front material 47 of the shoe, but not with the functional layer 49 of the top of the shoe, and on the other side is connected using the expansion joint 57 as with the functional layer 49 of the top of the shoe and the lining 51 of the top of the shoe products, and with a laminate 69 mounting soles. The sole unit 15 in this embodiment, along with the carrier layer 25 provided with the fiber layer 39 and the laminating layer 45, has only the sole undercarriage layer 29, into which the carrier layer 25 with the fiber layer 39 and the laminating layer 45 is embedded during molding of the sole layer 29 shown in FIG. 5. When casting the sole undercarriage layer 29 on the top 13 of the shoe, the liquid material of the undercarriage penetrates, on the one hand, through the mesh tape 71 to the protrusion of the end of the upper product functional layer 49 facing the sole and to the expansion joint 57 and, on the other hand, to the lower side of the peripheral edge zone of the mounting sole laminate 69, where it penetrates its lower textile layer and reaches there to the functional layer 37 of the bottom of the shoe. Thus, using the material of the undercarriage of the sole, the transition between the functional layer 49 of the top of the shoe and the functional layer 37 of the bottom of the top of the shoe is sealed.

In both the embodiments shown in FIGS. 4 and 5, the carrier layer 25 is preferably fabricated by injection molding. In this case, the laminating layer 45 and the fiber layer 39 can be inserted into the mold before the injection molding process. During the injection molding process, the material of the carrier layer 25 penetrates through the outer circumference of the laminating layer 45 and into the outer circumference of the fiber layer 39, so that the carrier layer 25, the laminating layer 45 and the fiber layer 39 are fixed to each other by the injection molding process .

In one modification of the embodiment shown in FIGS. 4 and 5, the fiber layer 39 and the laminating layer 45 are combined with each other in a node before connecting them to the plantar node 15. This node can form an insert that is manufactured separately from the other components of the plantar node 15 and inserted in the manufacture of the plantar site 15. This insertion is carried out in that layer of the sole, which should be provided with the site of the laminating layer 45 and the fiber layer 39.

In the embodiments shown in the figures, this insert is inserted into the carrier layer 25. In other embodiments not shown, in which the sole layer provided with a laminating layer 45 and the fiber layer 39 is formed not of a carrier layer, but, for example, of a sole or an intermediate sole of a different kind instead carrier layer, the insert can be inserted into the corresponding layer of the sole. That is, the insert is manufactured separately, and then, depending on the design and / or the desired appearance of the special plantar assembly 15, is inserted into a suitable sole layer. Inserts with optically different laminating layers 45 can be stored in the warehouse and inserted into the plantar assembly 15, depending on the type of shoe, the corresponding selected insert.

In the embodiment shown in FIG. 5, at least one of the stabilizing bridges is made in the form of a supporting bridge 73 inside the opening 27 of the carrier layer 25. For this purpose, the supporting bridge 73 is made so that it extends to the surface 75 of the onset layer 29 of the sole of the sole and thereby, while running, it leans together with the shoe, as well as the sole undercarriage layer 29, on the ground 77. Therefore, using the support bridge 73 shown in Fig. 5, particularly good stabilization of the sole assembly 15 is also achieved when running.
