METHOD FOR PRODUCING WATERPROOF SHOE PARTS, WATERPROOF SHOE PARTS PRODUCED BY MEANS OF SAID METHOD AND WATERPROOF SOLES FIXED WITH SAID SHOE PARTS

Abstract

The invention relates to a method for producing waterproof-breathable shoe parts (20), waterproof-breathable shoe parts (20) produced by said method, and waterproof-breathable soles (31) provided with said shoe parts (20). The method uses a mold (10a) of the type comprising a first element (11a) and a second element (12a), at least one of which has hollow regions (13a) of an impression matrix (14a), which are filled with a polymer material in the liquid state by depositing the latter in the hollow regions (13a) or by injecting the latter while the mold (10a) is closed. A support (17) consisting of a flexible sheet is interposed between the first element (11a) and the second element (12a) and includes a waterproof-breathable functional element (26) on which the polymer material hardens and adheres to the support (17) when the mold (10a) is closed.
