A vapor-permeable and waterproof sole for shoes, which comprises: - at least one first load-bearing component (12, 112), which has at least one vapor-permeable or perforated portion (13, 1 13), which comprises a vapor-permeable or perforated filler (14, 114), - at least one second component (19, 119), which is predominantly arranged below the first component (12, 1 12) and on which a tread (20, 120) is provided; this second component (19, 1 19) has through perforations substantially at the vapor-permeable or perforated portion (13, 1 13) of the first component (12, 112).Below the vapor-permeable or perforated portion (13, 113) and above the tread (20, 120) a membrane (21, 121) made of a material which is impermeable to water and permeable to water vapor is provided. The first component (12, 112) is constituted by a plastic midsole (15, 1 15), the outermost peripheral portion (16, 116) whereof, when the sole (11, 1 11) is associated with an upper, is visible. The midsole (15, 115) is rigidly coupled to the membrane (21, 121) and to the filler (14, 114) by molding before providing the tread (20, 120). A single peripheral seal is provided on the membrane (21, 121) and is formed by the molding of the midsole (15, 115); the midsole (15, 1 15) surrounds peripherally the membrane (21, 121).

L'invention concerne une semelle étanche à l'eau et perméable à la vapeur pour des chaussures, qui comprend : au moins un premier élément porteur (12, 112) qui présente au moins une partie perforée ou perméable à la vapeur (13, 113) comprenant un matériau remplissage perforé ou perméable à la vapeur (14, 114); au moins un second élément (19, 119) disposé en majeure partie sous le premier élément (12, 112) et sur lequel une bande (20, 120) est disposée, ce second élément (19, 119) présentant des perforations de passage sensiblement au niveau de la partie perforée ou perméable à la vapeur (13, 113) du premier élément (12, 112). Au-dessous de la partie perforée ou perméable à la vapeur (13, 113) et au-dessus de la bande (20, 120), une membrane (21, 121) faite d'un matériau imperméable à l'eau et perméable à la vapeur d'eau est disposée. Le premier élément (12, 112) est constitué d'une semelle intercalaire (15, 115) en plastique, la partie périphérique la plus extérieure (16, 116) de celle-ci étant visible lorsque la semelle (11, 111) est associée à une tige. La semelle intermédiaire (15, 115) est couplée de manière rigide à la membrane (21, 121) et au matériau de remplissage (14, 114) par moulage avant mise en place de la bande (20, 120). Un joint périphérique unique est disposé sur la membrane (21, 121) et est formé par le moulage de la semelle intermédiaire (15, 115); la semelle intermédiaire (15, 115) entourant de manière périphérique la membrane (21, 121).
