Abstract

A shoe structure includes an upper, including at least an outer layer and a lining, an insole, and a sole. The lining lines the inside of the outer layer and includes a waterproof and water-vapor permeable functional layer. The insole is connected to a lower end area of the outer layer. The lower end area of the lining is turned back to the inside in the sole area at least approximately parallel to the direction in which the sole extends, whereby the turned back area of the lining is shortened to a width of between 0.5 and 3 cm. Cut-outs are made in the insole, at least in the area in which the turned back lower end area of the lining ends. The lower end area of the lining is embedded in a synthetic material which fills the cut-outs in the insole in such a manner that at least the surface of the end area of the lining facing the inner area of the shoe structure forms a continuous surface with the surface of the synthetic material facing the inner area of the shoe structure. The functional layer is bonded with the synthetic material in a waterproof manner in the lower end area of the lining and at the extreme edge area of the lining.
