Definitions

• the following invention relates to a shaft assembly for footwear and footwear with such a shaft assembly.
• footwear 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.
• 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.
• the mounting sole may be equipped with openings or be made of a material permeable to water vapor.
• a suction element 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.
• the inventors have found that especially in the Schaftend Scheme, 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.
• 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.
• 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.

• the suction member 180 is embedded in the sealant without significantly affecting the suction effect.
• this suction element 180 moisture is transported away from the intermediate space to the outside. From the underside of the mounting base 162, this moisture can be further transported away through the recesses 60 in the sole unit 54.
• the shaft bottom functional layer laminate 164 is bonded to the mounting sole 162 by a water vapor permeable adhesive layer 170.
• the adhesive layer 170 which may be continuous or punctiform, in the exemplary embodiment of FIG. 7 covers a major part of the surface of the mounting base 162, penetrates through the mesh material 154 to the shaft bottom functional layer 166, and is made permeable to water vapor to flow therealong Body to ensure breathability.
• Fig. 8 shows a schematic view of the shaft assembly 100 from below.
• the lower peripheral edge of the shaft assembly 100 forming end portion of the upper 24, which is tweaked to the underside of the mounting base 42, can be clearly seen.
• the ends of the suction members designed as suction bands 184 which transport moisture downwardly out of the gap between the shank functional layer laminate and the topsheet layer.
• suction belts 184 of small width, distributed along the peripheral edge of the upper material layer 24, can be seen.
• Such an arrangement of a plurality of suction belts 184 along the entire circumference of the upper material layer 24 ensures a reliable removal of moisture from the intermediate space between the shank functional layer and the upper material layer in all circumferential regions of the shank arrangement.
• suction bands 184 may also be used in all other types of stem assemblies described above.
• FIG 9 shows a bottom view of an alternative embodiment of the shaft assembly 100 of the third shoe 98.
• suction belt 186 In this case, only one suction belt 186 is provided in a forefoot region of the shaft assembly 100, which extends a little way below the mounting sole 42. This suction belt 186 transports moisture out of the gap between the top material layer and the shaft functional layer laminate to the outside, and already by such a suction belt 186, a significant removal of moisture can be achieved.
