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).
Waterproof shoe structure with an exterior upper, an interior upper comprising a waterproof, water vapor permeable functional layer arranged adjacent to the exterior upper and a lining facing the shoe interior, an insole and an outsole, wherein the interior upper has a lower end region that substantially extends beyond a lower end of the exterior upper, and is joined to the exterior upper and to the insole, wherein the lower end region of the interior upper that extends beyond the exterior upper is folded outwards in such a way that the functional layer in the entire end region 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, and that the lower edge of the interior upper is joined to the insole.
