摘要

A method for providing parts of waterproof and breathable shoes (20), parts of waterproof and breathable shoes (20) provided with the method, and waterproof and breathable soles (31) provided with the 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 a matrix of impressions (14a), which are filled with polymeric material in the fluid state by depositing it in the hollow regions (13a) or by injecting it while the mold (10a) is closed. A support (17) made of flexible sheet is interposed between the first element (11a) and the second element (12a) and comprises a waterproof and breathable functional element (26), on which, when the mold (10a) is closed, the polymeric material sets and adheres to the support (17).
