A 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.
L'invention concerne un élément (10, 210, 310, 410, 510, 610) perméable à la vapeur qui peut être utilisé dans la composition de semelles pour chaussures, et qui comprend: - une base porteuse (11, 211, 311, 411) qui délimite sensiblement au moins un trou de passage important (12, 512); - une membrane (17, 117) imperméable à l'eau et perméable à la vapeur d'eau et placée au-dessus de la base porteuse (11, 211, 311, 411) de manière à couvrir au moins un trou de passage important (12, 512); - au moins une couche (19) de protection de la membrane, perméable à l'eau ou perforée, placée entre la base porteuse (11, 211, 311, 411) et la membrane (17, 117) de manière à couvrir au moins le trou de passage important (12, 512). La membrane (17, 117) et la couche de protection (19) sont jointes l'une à l'autre et à ladite base porteuse (11, 211, 311, 411) au moins au niveau des bords de leur périmètre; en coopération avec le dessin de la semelle avec lequel elle est associée, la couche de protection (19) peut être en contact avec le sol durant l'utilisation de la semelle.
