Abstract

A water-vapor permeable shoe-sole combination ( 15 ) with an upper side ( 5 ) having at least on through hole ( 31 ) extending through the thickness of the shoe-sole combination, a barrier unit ( 35 ) with an upper side forming at least part of the upper side ( 50 ) of the shoe-sole combination, made of a water-vapor permeable barrier material ( 33 ) that forms a barrier against penetration of foreign bodies, by means of which the at least one through hole ( 31 ) is closed in a water-vapor permeable manner, a reinforcement device ( 25 ) formed for mechanical reinforcement of the shoe-sole combination ( 105 ), constructed with at least one reinforcement web ( 37 ) arranged on at least one surface of the barrier material ( 33 ) and at least partially crossing the at least one through hole ( 31 ), and at least one walking-sole part ( 117 ) arranged beneath the barrier unit ( 35 ).

First claim

The invention claimed is:

1. Footwear with a water-vapor-permeable composite shoe sole with an upper side, the water-vapor permeable composite shoe sole comprising:
at least one through hole extending through the thickness of the composite shoe sole;
a barrier unit with an upper side forming at least partially the upper side of the composite shoe sole and with a water-vapor-permeable barrier material designed as a barrier against penetration of foreign objects, by means of which the at least one through hole is closed in a water-vapor-permeable manner;
a stabilization device assigned to the barrier material, designed for mechanical stabilization of the composite shoe sole, which is constructed with at least one stabilization bar, which is arranged at least on one surface of the barrier material and at least partially bridges at least one through hole;
and at least one outsole part arranged beneath the barrier unit, the footwear further comprising:
a shaft, which is provided on a shaft end area on the sole side with a waterproof and water-vapor-permeable shaft-bottom functional layer, wherein the shaft is constructed with at least one shaft material, whereby the shaft material has a waterproof shaft functional layer at least in the area of the shaft end area on the sole side, and whereby between the shaft functional layer and the shaft-bottom functional layer, a waterproof seal exists, and
wherein the shaft comprises a shaft bottom comprising a water-vapor-permeable shaft-mounting sole in addition to the shaft-bottom functional layer.

2. Footwear according to claim 1 , wherein the composite shoe sole is joined to the shaft end area provided with the shaft-bottom functional layer, so that the shaft-bottom functional layer is fully or largely unbonded to the barrier material, at least in the area of the at least one through hole.

3. Footwear according to claim 1 , wherein the shaft-mounting sole is connected to the shaft end area on the sole side by means of a Strobel seam.

4. Footwear according to claim 1 , wherein the shaft-bottom functional layer is arranged beneath the shaft-mounting sole and extends in a peripheral area beyond the periphery of the shaft-mounting sole into the shaft end area on the sole side.

5. Footwear according to claim 4 , wherein a sealing material is arranged between an end of the shaft functional layer on the sole side and the shaft-bottom functional layer in the peripheral area, where the shaft-bottom functional layer extends beyond the periphery of the shaft-mounting sole, with a waterproof connection between the end of the shaft functional layer on the sole side and the shaft-bottom functional layer being provided by means of the sealing material.

6. Footwear according to claim 5 , wherein the shaft-mounting sole is connected to the shaft end area on the sole side by means of a Strobel seam and wherein an outer material layer is shorter than the shaft functional layer in the shaft end area on the sole side, so that a protrusion of the shaft functional layer with respect to the outer material layer is present, wherein a mesh band is penetrated with the sealing material and is arranged between an end of the outer material layer on the sole side and the end of the shaft functional layer on the sole side, whose first long side, which faces away from the Strobel seam, is joined by means of a first seam to the end of the outer material layer on the sole side, but not to the shaft functional layer, and whose second long side, which faces the Strobel seam, is joined by means of the Strobel seam to the shaft-bottom functional layer.

7. Footwear according to claim 1 , with a shoe-bottom structure, having the composite shoe sole and the shaft-bottom functional layer situated above it, in which the shoe-bottom structure has a water-vapor transmission rate (MVTR) in the range from 0.4 g/h to 3 g/h.

8. Footwear according to claim 1 , wherein the barrier material is joined to the shaft bottom via an adhesive applied to the upper surface area of the barrier material that the shaft bottom is not joined to the barrier material wherever no material of the at least one stabilization bar is situated on the bottom of the barrier material.

9. A method for producing footwear with a water-vapor-permeable composite shoe sole and a shaft that is provided on a shaft end area on the sole side with a waterproof and water-vapor-permeable shaft-bottom functional layer, according to claim 1 , with the following process steps:
a) the composite shoe sole and shaft are prepared;
b) the shaft is provided on the shaft end area on the sole side with a waterproof and water-vapor-permeable shaft-bottom functional layer;
c) the composite shoe sole and the shaft end area on the sole side provided with the shaft-bottom functional layer are joined to each other in such a way, that the shaft-bottom functional layer is fully or largely unbonded to the barrier material, at least in the area of the at least one through hole.

10. Footwear with a water-vapor-permeable composite shoe sole with an upper side, the water-vapor permeable composite shoe sole comprising:
at least one through hole extending through the thickness of the composite shoe sole;
a barrier unit with an upper side forming at least partially the upper side of the composite shoe sole and with a water-vapor-permeable barrier material designed as a barrier against penetration of foreign objects, by means of which the at least one through hole is closed in a water-vapor-permeable manner;
a stabilization device assigned to the barrier material, designed for mechanical stabilization of the composite shoe sole, which is constructed with at least one stabilization bar, which is arranged at least on one surface of the barrier material and at least partially bridges at least one through hole;
and at least one outsole part arranged beneath the barrier unit, the footwear further comprising:
a shaft, which is provided on a shaft end area on the sole side with a waterproof and water-vapor-permeable shaft-bottom functional layer, wherein the shaft is constructed with at least one shaft material, whereby the shaft material has a waterproof shaft functional layer at least in the area of the shaft end area on the sole side, and whereby between the shaft functional layer and the shaft-bottom functional layer, a waterproof seal exists,
wherein the shaft-bottom functional layer is part of a multilayer laminate, and
wherein the shaft-bottom functional layer laminate is connected by a sewn seam to the end of the shaft functional layer on the sole side and a sealing material is applied in an area of the sewn seam, so that a waterproof connection between the end of the shaft functional layer on the sole side and a peripheral area of the shaft-bottom functional layer, including the sewn seam, is present.

11. Footwear according to claim 10 , wherein the laminate forms a shaft-mounting sole of the shaft.

12. Footwear according to claim 10 , wherein the sewn seam is a Strobel seam.

13. Footwear according to claim 10 , wherein the shaft comprises a shaft bottom comprising a water-vapor-permeable shaft-mounting sole in addition to the shaft-bottom functional layer.

14. Footwear according to claim 12 , wherein an outer material layer is shorter than the shaft functional layer in the shaft end area on the sole side, so that a protrusion of the shaft functional layer with respect to the outer material layer is present, wherein a mesh band or another material that can be penetrated with sealant is arranged between an end of the outer material layer on the sole side and the end of the shaft functional layer on the sole side,
