摘要

pA vapor-permeable element (10, 210, 310, 410, 510, 610) to be used in the composition of soles for shoes, which comprises: - a supporting frame (11, 211, 311, 411), which delimits substantially at least one large through hole (12, 512); - a membrane (17, 117) which is impermeable to water and permeable to water vapor and is arranged above the supporting frame (11, 211, 311, 411) so as to cover at least the large through hole (12, 512); - at least one vapor-permeable or perforated protective layer (19) for the membrane, which is arranged between the supporting frame (11, 211, 311, 411) and the membrane (17, 117), so as to cover at least the large through hole (12, 512).The membrane (17, 117) and the protective layer (19) are joined, at least at their perimetric edges, to each other and to said supporting frame (11, 211, 311, 411); the protective layer (19), in cooperation with the tread of the sole with which it is associated, is available for contact with the ground during use of the sole./p [WO2007147421A1]
