Abstract
Abstract A shoe, particularly for cross-country skiing, has an upper provided at a front tip region of the shoe with a layer of sheet material having an outer surface situated at the exterior of the shoe. This layer of sheet material has a lower edge region which extends outwardly away from an insole of the shoe. The shoe includes an outsole in the form of a casting made in a suitable mold or die. The above outwardly extending lower edge region of the layer of sheet material at the front tip of the upper is embedded in the outsole during the casting thereof so as to achieve in this way a secure connection between the shoe upper, particularly at its front tip region, and the outsole.
