Abstract:
A waterproof shoe having a structure comprising:a lining with a lining membrane which is permeable to vapor and impermeable to water; a breathable upper, internally associated with the lining; an insole, which is perimetrically associated with the upper and the lining; a sole element, which is made of a material impermeable to water which is directly injection-molded at least around an edge region of all of the upper, the lining, and the insole, when assembled, a lower edge of the lining protruding further downwardly than the upper to form a lower region; and a connecting element which replaces, at the lower region, the upper, the connecting element being joined to the upper on one side and to the insole on the other side, and comprising waterproof material being compatible, for adhesive bonding with the injection-molded material of the sole element, the connecting element being constituted by a sheet formed by at least two layers, a first layer which is directed toward the lining and is made of a first material adapted for sealing the lining membrane, the first material having a melting point which is lower than a temperature generated during molding, and a second layer being made of any of a fabric or a second material compatible with the injection-molded material of the sole element, the second material having a higher melting point than the first material in order to avoid melting thereof during preparation of an upper part of the shoe, by way of heat application.
