Description

Shaft assembly for footwear and footwear with it

The following invention relates to a shaft assembly for footwear and footwear with such a shaft assembly.

In the prior art, footwear is known, which is equipped with a waterproof and water vapor permeable shaft, so that such footwear despite water tightness in the shaft area can release sweat moisture to the outside. So that even in the sole region sweat moisture can escape to the outside, also sole areas of footwear were equipped with waterproof and water vapor permeable sole functional layers. An example of this, in which both the shaft bottom and the remaining shaft region are provided with water vapor permeable, but waterproof functional layers, and in which the shaft bottom is separated from the shaft region, is known from DE 10 2008 029 296 A1.

With such footwear, the problem may now arise that at the lower ends of the shaft area stains appear on the upper at this point and that, especially in cold weather, an uncomfortable feeling of coldness arises on the foot.

It is therefore an object of the present invention to provide a shaft assembly for footwear and footwear so that in the end of the shaft portion in front of the shaft bottom no such unpleasant feeling of cold results and in which preferably at this point also staining on the upper material is avoided. Furthermore, the breathability should be ensured at this point.

This object is solved by the subject matter of the independent patent claims. Advantageous developments emerge from the dependent claims.

A shank arrangement according to the invention for footwear comprises a shank floor with a water vapor permeable mounting base and with a shaft floor functional layer laminate and a shaft area with a top material layer and with a feed layer. The sole side shaft end portion is connected to the peripheral edge of the shaft bottom. There are several constructive designs for this, as will be explained below.

The mounting sole may be equipped with openings or be made of a material permeable to water vapor.

According to the invention, a suction element is now provided which extends from a region between the upper material layer and the feed layer of the shaft region into a region below the shaft bottom functional layer laminate in order to transport moisture away from the region between the upper material layer and the feed layer of the shaft region into the region below the shaft bottom functional layer laminate , From there, the moisture can be released further outwards, in particular in the case of a shaft arrangement connected to a sole unit, through passages or porosities in the sole unit.

According to one of the underlying recognition of the invention, the inventors have found that especially in the Schaftendbereich, which is indeed usually waterproof connected to the peripheral edge of the shaft bottom, often moisture accumulates and this condenses there often to water. This has the consequence that the area of the foot lying opposite the feed layer experiences a feeling of coldness there, that, when the feed layer is formed as a shank functional layer, no sufficient water vapor gradient can form at this point between the inside and the outside of the shank functional layer that the breathability in this area is significantly reduced or no longer exists, that on the outside of the shoe on the water vapor permeable upper material layer show moisture spots that affect the look and appearance of the shoe, and that this can eventually lead to mold growth or the joints are attacked, which in the worst case makes the shoe broken. In accordance with one aspect of the invention, an additional absorbent member of absorbent material is now provided which extends into an end portion of the shaft portion where such moisture typically gathers and extends therefrom to an area below the shaft bottom functional layer laminate. By means of such a suction element, moisture is removed from the intermediate space between the upper material layer and the feed layer in the end section of the shaft region which adjoins the shaft bottom and from there is transported away into the region below the shaft bottom functional layer laminate, from where this moisture retracts the shoe, in particular down through recesses or porosities in the sole unit can leave. This prevents an unpleasant feeling of coldness in this area, maintains breathability in this area, and reliably prevents staining and joint damage. The suction element can also be referred to as a "wicking tape" and has the function of a wick. Such a suction element can be provided in a variety of shaft assemblies for footwear, as will be explained below.

In all embodiments, the lining layer may be suitably joined to the upper, for example, sewn thereto at a top.

According to a first embodiment of the invention, the feed layer is designed as a sheath functional layer laminate in order to ensure water-tightness with simultaneous water vapor permeability breathability.

According to a further embodiment of the invention, at least one suction element is band-shaped. This represents a manufacturing technology easy to implement variant, with a very reliable liquid removal is guaranteed.

In a further embodiment of the invention, at least one suction element extends from a portion of the sohienseitigen peripheral edge of the shaft portion to an opposite, in particular in the shoe transverse direction opposite portion of the sohienseitigen peripheral edge. One of like suction element thus extends with its two ends in each case opposite intermediate spaces between the upper material layer and the feed layer and thus transports moisture from two opposing spaces to the underside of the shaft bottom functional layer laminate. This is a very advantageous and easy to implement embodiment.

According to a further embodiment of the invention, at least one suction element has a planar extent of such a width that it extends over a portion of at least 25% of the sole side peripheral edge of the shaft portion, in particular over the forefoot portion of the sole side peripheral edge of the shaft portion. Thereby, the possible liquid removal can be maximized.

According to a further embodiment of the invention, in which a continuous liquid removal is ensured at all peripheral regions of the shoe, a plurality of suction element, in particular band-shaped suction elements along the sole side peripheral edge of the shaft portion are arranged.

In an alternative embodiment, exactly one suction element is arranged on the sole-side peripheral edge of the shaft region. For this purpose, it is advisable to provide this suction element at that circumferential point of the shaft assembly, which accumulates the most moisture, for example in a forefoot portion of the shaft assembly.

Essentially any moisture-absorbing and transporting materials are suitable for the suction element. As an advantageous material, cotton has been found.

A suction element according to the invention can be fixed in various ways with respect to the shaft arrangement. In order to pass the transition between the Schaftendbereich and the shaft bottom, such a suction element usually has to pass the connection provided therebetween. In practice, such a suction element is often used over hardened, in Umfangsrich- placed on the top layer of applied adhesive bonding points. The suction element can also be sewn to the mounting sole and / or to the upper material layer at at least one point.

For permanent attachment of the suction element, it may be provided with an adhesive at least in some areas. In particular, the suction element can be glued to the underside of the shaft bottom functional layer laminate in order to achieve a fixation there.

In order to transport sufficient moisture out of the intermediate space between the upper material layer and the feed layer of the shaft region, it is advantageous if the suction element with its gap-side section extends approximately one to three centimeters, in particular approximately two centimeters, into this intermediate space.

In order to be able to deliver the moisture absorbed in the intermediate space and transported into the region below the shaft bottom functional layer laminate further to the environment, it has proven advantageous if the suction element with its shaft bottom functional layer laminate side section is approximately one to four centimeters, in particular approximately three Centimeters into the area under the shaft bottom functional layer laminate.

Thus, in an advantageous embodiment of the invention, a total length of the Saugelements of three to seven centimeters, preferably from about five centimeters result.

According to a construction variant of the shank arrangement according to the invention, the water vapor-permeable mounting sole, which is often referred to as an insole, is arranged above the shaft bottom functional layer laminate. In this case, the suction member extends with its shaft bottom functional layer laminate side portion on the outside of the shaft bottom. With such a construction, a particularly effective removal of moisture can be achieved, especially since the moisture can be discharged from the shaft bottom-function-layer laminate-side section directly to the environment. In this construction, the water vapor permeable mounting sole may be sewn to the sole side end portion of the shank functional layer laminate, for example by means of a strobel seam or a zigzag seam, and additionally, the sole side end portion of the upper material layer of the shank portion may be pinched onto the underside of the shank bottom functional layer laminate.

According to an alternative construction of the shaft arrangement, which is also often referred to as bootie, the sole-side end portion of the shaft functional layer laminate is sewn to the peripheral edge of the shaft bottom functional layer laminate, for example by means of a zig-zag seam, and watertight sealed to each other via a waterproof sealing tape. In this construction, the moisture vapor permeable mounting sole is disposed below the shaft bottom functional layer laminate.

With this type of construction, the first alternative now arises that the sole side end region of the upper material layer is sewn to the water vapor permeable mounting sole. In this case, the suction member extends from the space between the top sheet layer and the shaft-functional layer laminate into a space between the shaft bottom functional layer laminate and the water vapor-permeable mounting sole. The moisture transported away from the intermediate space between the upper material layer and the shaft functional layer laminate into the region below the shaft bottom functional layer laminate must now penetrate the moisture vapor permeable mounting sole so that it can be transported away to the outside. It has been found that even with this construction, a sufficiently large removal of moisture can be achieved.

According to an alternative construction, the sole-side end region of the upper material layer is pinched onto the underside of the mounting sole, and in this case the suction element extends to the outside of the shaft bottom. In this case, a particularly good removal of moisture can be achieved. In principle, the shaft assembly according to the invention is not limited to specific design variants, but can be used in a variety of arbitrary design variants. The formation of the shank functional laminate and the shank functional layer laminate are not important.

The invention also relates to footwear with at least one shaft assembly of the type described above, on the underside of a sole unit is attached. The sole unit can be connected to the shaft arrangement in any manner, it is preferred that the sole unit is glued or molded onto the shaft arrangement. The sole unit must, in order to ensure a sufficiently large moisture removal, be equipped with at least one through hole or with porosities that lead downwards or sideways outwards.

Definitions and test methods

Footwear:

Footwear with a closed top (shaft assembly) having a foot insertion opening and at least one sole or sole unit.

Shaft Upper:

A material which forms the outside of the shaft and thus the shaft assembly and consists for example of leather, a Texti), plastic or other known materials and combinations thereof or is constructed therewith and generally consists of water vapor permeable material. The sole-side lower end of the upper upper material forms an area adjacent to the upper edge of the sole or sole unit or above a boundary plane between the upper and sole or sole unit.

Mounting sole (insole): A mounting sole is part of the shaft bottom. On the mounting sole, a sole-side lower shaft end region is attached.

Sole:

A shoe has at least one outsole, but may also have several types of sole layers which are arranged one above the other and form a sole unit.

Sole:

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

Midsole:

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

Bootie:

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

Functional layer:

Waterproof and / or water vapor permeable layer, for example in the form of a membrane or a suitably treated or finished material, for. B. a textile with plasma treatment. The functional layer may be in the form of a shaft bottom functional layer at least one layer of a shaft Floor of the shaft assembly form, but can also be provided as a shaft at least partially lining shaft function layer. Both the shank functional layer and the shank bottom functional layer can be part of a multilayer, mostly two-, three- or four-ply membrane laminate. The shaft functional layer and the shaft bottom functional layer may each be part of a functional layer bootie. If, instead of a functional layer bootie, a shank functional layer and a separate shaft bottom functional layer are used, they are sealed against each other in a watertight manner, for example, in the lower side region of the shank arrangement on the side of the sole. Shank bottom functional layer and shank functional layer may be formed of different or the same material.

Suitable materials for the waterproof, water-vapor-permeable functional layer are, in particular, polyurethane, polypropylene and polyester, including polyether esters and their laminates, as described in the printed publications US Pat. No. 4,725,418 and US Pat. No. 4,493,870. In one embodiment, the functional layer is constructed with microporous, stretched polytetrafluoroethylene (ePTFE), as described, for example, in US-A-3,953,566 and US-A-4,187,390. In one embodiment, the functional layer is constructed with stretched polytetrafluoroethylene provided with hydrophilic impregnating agents and / or hydrophilic layers; See for example the document US-A-4, 194.041. A microporous functional layer is understood as meaning a functional layer whose average pore size is between approximately 0.2 μm and approximately 0.3 m.

laminate:

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

Barrier layer:

A 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 a material layer to be protected, in particular to a mechanically sensitive functional layer or functional layer membrane.

Reference document:

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

Waterproof:

As "waterproof" a functional layer / functional layer laminate / membrane is considered, optionally including on the functional layer / functional layer laminal / membrane provided seams, if it ensures a water inlet pressure of at least 1 * 10 ⁴ Pa. The functional layer material preferably ensures a water inlet pressure of more than 1 × 10 ⁵ Pa. The water inlet pressure is to be measured by a test method in which distilled water is applied at 20 +/- 2 ° C. to a sample of 100 cm ^{2 of} the functional layer with increasing pressure. The pressure increase of the water is 60 +/- 3 cm Ws per minute. The water inlet pressure then corresponds to the pressure at which water first appears on the other side of the sample. Details of the procedure are specified in the ISO standard 0811 from the year 1981. Whether a shoe is waterproof, z. With a centrifuge arrangement of the type described in US Pat. No. 5,329,807.

Water vapor permeable:

As a "water vapor permeable" a FunktionsschichVein functional layer laminate is considered if it / has a water vapor transmission rate Ret of less than 150 m2 * Pa * W - 1. The water vapor permeability is tested according to the Hohenstein skin model. This test method is described in DIN EN 31092 (02/94) or ISO 11092 (1993).

FIG. 12 shows a sectional view of an exemplary suction element from FIG. 4.

All shoes described below as exemplary embodiments have a sole unit and a shaft arrangement to be fastened thereto. In the embodiments described below, the sole unit is glued to the shaft assembly. It is equally possible to inject the sole unit onto the shaft arrangement.

All subsequent illustrations are schematic and not necessarily realistic in terms of dimensions and scale.

FIG. 1 shows a sectional view of a front foot region of a first shoe 2 according to a first exemplary embodiment of the invention.

The first shoe 2 comprises a sole unit 4 and a shaft assembly 22 which are not yet connected to each other.

The shaft arrangement 22 comprises a shaft bottom 34 and a shaft region 23 connected therewith at its peripheral edge, of which a left and a right shaft section, which are mirror-symmetrical to one another, are shown in FIG. The upper portion of the shaft portion 23 is in this as well EP2011 / 051014

not shown in the following figures for simplicity.

The shaft region 23 has a water vapor-permeable upper material layer 24 and a shaft functional layer laminate 26, which comprises-from the outside to the inside-a mesh or a mesh 28, a shaft functional layer or a shaft membrane 30 and a shaft lining 32.

The sole-side lower end region of the upper material layer 24 is bent inwards relative to the substantially vertical section and fastened by means of Zwickklebstoff 44 with the multilayer shaft bottom 34.

The multi-layered shaft bottom 34 comprises, from top to bottom, a mounting sole 36 and a shaft bottom functional layer laminate 38 having a shaft bottom functional layer 40 and a bottom textile layer 42 , For example, a stitching seam or a zig-zag seam, connected to the sole-side end portion of the Schaftfunktionsschichtlami- nats 38.

The shaft bottom functional layer laminate 38 is thus formed as a two-ply laminate. As can be seen well in FIG. 1, the shaft bottom functional layer laminate 38 has a greater lateral extent than the mounting base 36 in order to connect it watertight to the sole end region of the shaft functional layer laminate 26 and to the upper material layer 24, e.g. by gluing.

The sole-side lower end portion of the upper-material layer 24 is twilled with its upper side by means of a Zwickklebers 44 on the underside of the peripheral edge of the Schaftbodenfunktionsschichtlaminats 38.

The sole side lower end portion of the shaft functional layer laminate 26 is lifted from the sole side lower end portion of the upper material layer 24. This creates a gap in the end portion of the shaft portion 23 between the shaft functional layer laminate 26 and the upper material layer 24, which widens toward the end portion of the shaft portion 23. The shaft bottom functional layer laminate 38 extends a little way into this space. The portion of the gap not occupied by the end portion of the shaft bottom functional layer laminate 38 is usually filled with air or water vapor or a mixture thereof.

Further, the underside of the sole-side end portion of the shank functional layer laminate 26 is waterproof-bonded to the top of the peripheral edge of the shank bottom functional layer laminate 38 by means of a sealant adhesive 48, including or excluding the seam 46 (46), resulting in a fully watertight and in use not only waterproof, but also water vapor permeable functional layers 26, 38 leads to a completely water vapor permeable shaft assembly.

This sealing adhesive 48 penetrates through the net 28, thus sealing both functional layers to each other, and serves to attach and seal the shaft bottom functional layer laminate 38 to the shaft functional layer laminate 26, so that no additional adhesive is required for this purpose.

The sole unit 4 is prefabricated and is attached to the sole side lower end portion of the upper material layer 24 by means of a sole adhesive applied to at least the top of the peripheral edge zone of the sole unit 4. In the present exemplary embodiment, a first sole-adhesive layer 20 is applied to the upper side of the peripheral edge zone of the sole unit 4, and a second sole-adhesive layer 50 is applied to the sole-side lower end region of the upper-material layer 24.

The sole unit 4 comprises a sole layer 6 which forms the peripheral outer region thereof and extends somewhat upwards in its outer side in order to accommodate the bent region of the upper material layer 24 and which has a central recess in which - from below to above - a support web layer 8, a barrier layer 16 and above the barrier layer 16 a comfort layer 10 are arranged with comfort webs.

The adhesive layer 20 extends, as can be clearly seen in FIG Only the upper region of the sole layer 6 and the upper sides of the comfort webs of the comfort layer 10 can be configured without adhesive layer 20.

In Fig. 1 of the support web layer 8, three support webs and of the comfort layer 10 three comfort webs are shown, which are slightly wider than the supporting webs arranged underneath. Furthermore, the comfort layer 10 comprises still narrower comfort web sections which attach to the inside of the sole layer 6.

The lower surface of the sole layer 6 and the support web layer 8 is formed as running or tread surface 14. Recesses or Sohlenlagendurchgangsöffnungen 12 are formed between the support webs of the support web layer 8, to effect a water vapor permeability and / or air permeability of the sole layer 6 with support webs 8.

The sole layer 6 can be in one piece, as shown in the figure, or in several parts, for example in different colors.

The Sohlenlagendurchgangsöffnungen 12 are made as large as possible in order to achieve a correspondingly high water vapor permeability of the sole layer 6 with support webs 8 and thus the sole unit 4.

Horizontally through the sole unit 4 extends a barrier layer 16 as a mechanical protection for the shaft bottom functional layer laminate 38 against damage by foreign bodies, such as pebbles, which enter the Sohlenlagendurchgangsöffnungen 12. This barrier layer 16 extends a little way into the sole layer 6 in and is thus anchored in this and permanently connected to this. This barrier layer 16 is constructed in one embodiment with a thermally bonded fiber material, so that it can also be formed as a stabilizing material for the sole unit 4. The support web layer 8 and the comfort layer 10 may be made of a different material compared to the sole layer 6, as indicated by the different hatching, to achieve a weight reduction of the sole unit 4, a walking comfort improved with respect to the foot cushioning, or both. Alternatively, the support web layer 8, the comfort layer 10 and the sole layer 6 may also be made of the same material.

In particular, a material that is softer than the material of the sole layer 6 can be selected for the support web layer 8 and the comfort layer 10. If good foot cushioning is to be achieved, the material for the support web layer 8 and / or the comfort layer 10 is, for example, EVA. If a weight reduction compared to the sole layer material is to be achieved, a foamed plastic with correspondingly low specific weight is suitable. For example, in order to achieve both improved cushioning and weight reduction with respect to the sole ply material, foamed EVA is suitable. But there are many other material variants that can be used

Below the barrier layer 16 is still optionally a decorative layer 18, which is visible from below and causes an attractive design of the sole unit.

Fig. 2 shows a sectional view of a forefoot portion of a second shoe 52 according to a second embodiment of the invention.

Like the first shoe 2, the second shoe 52 also includes a sole unit 54 and a shaft assembly 70 that are not yet connected to each other. The shaft assembly 70 is constructed according to the bootie principle, and it comprises a shaft bottom 80 and a shaft portion 71 connected thereto at its peripheral edge, of which in the figure 2, a left and a right shaft portion are shown, which are mirror-symmetrical to each other.

The shaft portion 71 comprises a water vapor permeable topsheet layer 72 and a three layer shaft functional layer laminate 74 comprising an inner shaft liner 78, an outer shank functional layer or membrane 76 and a Mesh or mesh 75 includes.

The upper material layer 72 of the shaft region 71 extends somewhat further in the direction of the shaft bottom 80 than the shaft functional layer laminate 74. The shaft functional layer laminate 74 is connected to a shaft bottom functional layer laminate 84 of the shaft bottom 80 by means of a seam, which can be designed in particular as a zigzag seam and the seam 90 is sealed watertight outwardly with a seam sealing tape 92.

The shaft bottom functional layer laminate 84, like the shaft functional layer laminate 74, has a two layer construction with an inner support fabric layer 88 and an outer shaft bottom function or membrane 86. The functional layers 76 and 86 as well as the textile layers 78 and 88 of the shaft functional layer laminate 74 and the shaft bottom functional layer laminate 84 are sewn together so that the textile layers 78 and 88 and the functional layers 76 and 86 each adjoin one another.

In the illustration according to FIG. 2, there is a distance between the outer surface of the shaft functional layer 76 and the inner surface of the upper material layer 72; in practice, these surfaces can also lie directly against one another.

Enclosed by the upper material layer 72 of the shaft region 71 and sewn to the sole-side end region of the upper material layer 72 is a mounting sole or insole 82, which is arranged below the upper shaft functional layer laminate 84 and has a somewhat smaller areal extent. The seam 94 between the sole-side end region of the upper material layer 72 and the peripheral edge region of the mounting sole 82 can be embodied in particular as a stitching seam or as a zig-zag seam.

Like the sole unit 4 of the first shoe 2, the sole unit 54 of the second shoe 52 is prefabricated and is by means of a sole adhesive, which has been applied at least to the top of the peripheral edge zone of the sole unit 54, at the lower side of the bottom side Obermatterialla- 72 and additionally attached to the sole side lower edge region of the mounting sole 82. In the present embodiment, a first sole adhesive layer 68 is applied on the upper side of the peripheral edge zone of the sole unit 54 and a second sole adhesive layer 96 on the sole side lower end region of the upper material layer 24 and on the sole side lower edge region of the mounting sole 82.

The sole unit 54 comprises, like the sole unit 4, a sole layer 56 which forms the peripheral outer region of the sole unit 54 and is provided with a central recess in which - from bottom to top - a support web layer 58 with three supporting webs shown by way of example in FIG Barrier layer 64 are arranged. The barrier layer 64 runs horizontally through the sole unit 4 and extends with its peripheral edge region into the upper end of the sole layer 56. It is thus reliably connected to the sole layer 56. The support ribs extend from the barrier layer 64 to the plane of the underside of the sole ply 56, and the lower surface of the sole ply 56 and the support ribs 58 form the running or tread surface 62. Unlike the sole unit 4 of the first shoe 2, in the sole unit 54 no additional comfort situation provided, but could be added if necessary.

The optionally present below the barrier layer 64, optional decorative layer 66 corresponds to the decorative layer 18 of the first sole unit. 4

In both the shaft assembly 22 of the first shoe 2 in FIG. 1 and the shaft assembly 70 of the second shoe 52 in FIG. 2, the shaft bottom functional layer laminate 38 and 84 is formed in two layers and includes only one shaft bottom functional layer 40 and 86, respectively, and a backsheet layer 42 or 88, but not another layer. In the present embodiments of Figures 1 and 2, the mesh or net material, often referred to as mesh, is omitted.

Especially at the shaft bottom 34 and 80, the accumulation of abzutransportierendem, generated by the sole of the foot perspiration is greatest. In addition, located below the shaft bottom 34 and 80 with the recesses 12 and 60, respectively largest openings, so the potential for moisture removal is greatest at this point.

The inventors of the present application have found that at this point an additional third layer of the shaft bottom functional layer laminate 38 or 84 can be dispensed with and the shaft functional layer laminate 38 or 84 can be formed in two layers in this region, which reduces the cost of a third layer can be saved and by omitting this third layer and the amount of sweat that can be removed, is increased. With the omission of the third layer of the shaft bottom functional layer laminate, a water vapor barrier to be overcome by the moisture is removed.

Surprisingly, however, a watertight connection is possible, although no additional layer, for example the net strip, is more present.

In the case of the shaft arrangement 22 of the first shoe 2 according to FIG. 1, this two-layer shaft bottom functional layer laminate 38 is arranged directly above the recess 12, which permits a particularly effective removal of the moisture from the interior of the shaft arrangement 22, and with the shaft arrangement 70 of the second shoe 52, as shown in FIG. 2, under the two-layer shaft bottom functional layer laminate 84, the mounting sole 82 is still arranged, through which the moisture still has to pass.

3 shows an isolated sectional view of a section of the two-ply shaft bottom functional layer laminate 38 of the shaft bottom 34 of the shaft arrangement 22 from FIG. 1.

In this case, the lowermost support textile layer 42 and the somewhat thinner shaft bottom functional layer 40, which forms the actual membrane, are clearly visible.

4 shows a sectional view of a forefoot region of a third shoe 98 according to a further exemplary embodiment of the invention. The third shoe 98 comprises a sole unit 4 which is identical to the sole unit 4 of the first shoe 2 of Fig. 1, and a shaft assembly 100 which coincides with the shaft assembly 22 of the first shoe 2, in contrast to this as an additional element Suction element 102 is provided.

Elements of the third shoe 98 which coincide with the elements of the first shoe 2 are identified by the same reference numerals.

The suction belt 102 extends from the space between the outer mesh 28 of the sheath functional layer laminate 26 and the inner side of the upper material layer 24 to the outside of the shank assembly 100 below the support fabric layer 42.
