Abstract

Item of footwear having an upper arrangement and a sole, wherein the upper arrangement has a top material and an air-permeable layer arranged in a base of the upper, the air-permeable layer is arranged above the sole, in a sole-side, bottom region of the upper arrangement, the air-permeable layer has a three-dimensional structure allowing the through-passage of air in at least the horizontal direction, and a sole-side, bottom peripheral region of the top material of the upper is replaced, over at least part of its peripheral extent, by at least one connecting material which, beginning at least above an underside of the air-permeable layer and running outside the air-permeable layer, is arranged on the base of the upper and is air-permeable at least in a sub-region located at least in part at the same level as the air-permeable layer and thus connects the air-permeable layer to the exterior surroundings such that air can be exchanged between the exterior surroundings and the air-permeable layer.

First claim

The invention claimed is:

1. A shoe having
a) a shaft arrangement and a sole, wherein:
b) the shaft arrangement has
b.1) an outer shaft material and
b.2) an air-permeable layer arranged in a shaft bottom;

c) the air-permeable layer is arranged in a lower area of the shaft arrangement on the sole side above the sole
d) the air-permeable layer has a three-dimensional structure that permits air passage at least in the horizontal direction through the air-permeable layer and is embodied as an air-permeable spacer structure; and
e) the outer shaft material has at least two at least roughly opposite air-passage openings in a lower peripheral area on the sole side and in the foot transverse direction or foot longitudinal direction, said openings connect the air-permeable layer to the outer surroundings in a horizontal direction for a convective air exchange through the air-permeable layer between the outer surroundings and the air-permeable layer.

2. The shoe according to claim 1 that has a water vapor-permeable functional layer at least in a lower area of the shaft arrangement that faces the sole, the air-permeable layer being arranged beneath the functional layer.

3. The shoe according to claim 2 , wherein the functional layer is waterproof.

4. The shoe according to claim 2 with a shaft functional layer and a shaft-bottom functional layer.

5. The shoe according to claim 4 , with a functional layer bootie, in which a shaft area is formed at least partially by the shaft functional layer and a shaft bottom area is formed by the shaft-bottom functional layer.

6. The shoe according to claim 4 , wherein the functional layer of the shaft functional layer and the shaft bottom functional layer are part of an at least two-layer laminate.

7. The shoe according to claim 6 , wherein the laminate is a shaft-bottom functional layer laminate or a shaft functional layer laminate.

8. The shoe according to claim 2 , wherein the functional layer has a water vapor-permeable membrane.

9. The shoe according to claim 2 , wherein the functional layer has a membrane constructed with expanded microporous polytetrafluoroethylene (ePTFE).

10. The shoe according to claim 4 , wherein the air-permeable layer is situated beneath the shaft-bottom functional layer.

11. The shoe according to claim 10 , wherein the air-permeable layer is situated directly beneath the shaft-bottom functional layer.

12. The shoe according to claim 2 , wherein the air-permeable layer is at least water vapor-permeable in the direction toward the functional layer.

13. The shoe according to claim 2 , wherein the at least one air-passage opening is arranged in the outer shaft material least partially at the same height as the air-permeable layer.

14. The shoe according to claim 1 , wherein the at least one air-passage opening has a total surface of at least 50 mm 2 .

15. The shoe according to claim 1 , wherein a lower area of the outer shaft material on the sole side forms a lasting edge, and the air-permeable layer is arranged above the lasting edge of the outer shaft material.

16. The shoe according to claim 1 , wherein the shaft arrangement comprises an inlay sole and an additional inlay sole which is arranged beneath the air-permeable layer.

17. The shoe according to claim 1 , wherein a penetration-protection element is arranged in above sole.

18. The shoe according to claim 1 , said air-permeable spacer structure has a flat structure and a plurality of spacer elements extending away from the flat structure, vertically or at an angle between 0 and 90°.

19. The shoe according to claim 18 , wherein the spacer elements are embodied as knobs.

20. The shoe according to claim 18 , wherein the air-permeable spacer structure is constructed with two parallel arranged flat structures, and the two flat structures are joined to each other and held spaced from one another in an air-permeable manner by spacer elements.

21. The shoe according to claim 1 , said spacer structure is constructed with a reinforced knit.

22. The shoe according to claim 1 , said spacer structure is constructed to be corrugated or sawtooth-shaped.

23. The shoe according to claim 1 , in which the at least one air-passage opening has shape selected from the group consisting of round and angular.

24. The shoe according to claim 1 , in which the at least one air-passage opening is covered with an air-permeable protective material in the form of a gauze or mesh.

25. The shoe according to claim 1 , in which the at least one air-passage opening is sealed by a device.
