Abstract
A shoe structure includes an upper made of an outer material, a waterproof and water vapor permeable functional layer, a lining, an insole, and an injection-molded sole. The upper has an extension made of a porous, permeable material and the insole is joined to the extension of the upper. The functional layer and the lining extend beyond a lower edge of the upper and only partially overlap the extension of the upper. The functional layer is spaced from an edge of the insole and the extension of the upper is penetrated by the material of the sole. A part of the functional layer extending beyond a lower edge of the upper is joined to the material of the sole, and a space between the functional layer and the edge of the insole is filled with the material of the sole as far as the interior of the shoe structure.
