Problems solved by technology

However, it has been found that when wearing this known shoe construction, the lower end region of the inner upper, especially the region where the ankle is located, is often not able to withstand high stresses; the functional layer thus cracks and is no longer waterproof

Embodiment Construction

[0021] As can be seen from the embodiments in the accompanying drawings, the shoe structure of the present invention has an outer upper 1; an inner upper comprising at least waterproof and water vapor permeable functional layers 2a, 2b and a lining 2; an insole 4; and an outer shoe Bottom 6. The end regions of the inner side extending beyond the outer part 1 are folded outwards, so that the functional layer located in the entire end region is folded in half and has a lower edge produced by the folding. In the end region of the inner upper, the inner upper is not lined as far as the shoe interior, so that in this region the functional layer 2 a adjoins the outsole and is thus connected to the outer sole to a wider extent. By removing the lining, a wide range of, in particular waterproof, bonds can be produced between the functional layer and the material of the outsole.

[0022] The inner side can also comprise another fabric layer (not shown in the figure for clarity) which i...

Abstract

A waterproof shoe structure having an exterior upper (1), an interior upper including a waterproof, water vapor permeable functional layer (2a) arranged adjacent to the exterior upper (1) and a lining (2) facing the shoe interior, an insole (4, 4a, 4c) and an outsole (6), wherein the interior upper has a lower end region (2b) that extends at least for the most part beyond the lower end of the exterior upper, and which is joined on the one hand to the exterior upper (1) and on the other hand to the insole (4, 4a, 4c). The lower end region of the interior upper that extends beyond the exterior upper (1) is folded outwards in such a way that the functional layer in the entire end region (2b) is turned back on itself, and the interior upper has a lower edge arising from this folding, that the free end of the outwardly folded interior upper is joined to the exterior upper (1), and that the lower edge of the interior upper is joined to the insole (4, 4a, 4c).

Description

technical field [0001] The invention relates to a waterproof shoe structure having: an outer upper (exterior upper); an inner upper (interior upper) comprising a waterproof and water vapor permeable functional layer and a lining facing the inside of the shoe; an an insole; and an outsole, wherein the inner upper has a lower end region which extends at least largely beyond the lower end of the outer upper and is connected to the outer upper on the one hand and to the insole on the other hand. technical background [0002] A shoe construction of this type is known from EP0544270A1. In this case, the inner upper is glued to the outer upper on the one hand and connected to the insole on the other hand, with the result that the outer upper is connected to the insole via the lower end region of the inner upper . The outer shell is also joined to the insole by means of an injected sole material, wherein the sole material located between the outer shell and the insole adheres to t...
