A breathable shoe, including: an upper assembly (10, 310, 410) having a breathable upper (11, 311, 411); a membrane (14, 314, 414) made of a material which is waterproof and breathable, and a sole (16, 116, 216, 316, 416) made of perforated elastomer, which are all mutually attached such that the membrane is arranged between the upper assembly and the sole, and the sole is sealed perimetrically to the membrane, in a manner to prevent moisture to enter into the upper assembly from the sole through the membrane, and to permit moisture to leave the inside of the upper assembly through the membrane and through the sole. In one preferred embodiment, the membrane is first attached to the upper assembly so that the upper assembly is a unitary upper assembly including the membrane, and such unitary upper assembly is subsequently attached to the sole.

L'invention concerne une chaussure respirante composée d'un assemblage de tige (10, 310, 410) doté d'une tige respirante (11, 311, 411), d'une membrane (14, 314, 414) de matériau imperméable et respirante et d'une semelle (16, 116, 216, 316, 416) en élastomère perforé. Ces éléments sont mutuellement fixés de manière à ce que la membrane soit disposée entre l'assemblage de tige et la semelle. Celle-ci est fixée de manière étanche autour de la membrane, afin d'empêcher l'humidité de pénétrer à l'intérieur de l'assemblage de tige en passant de la semelle à la membrane et en permettant à l'humidité de quitter l'intérieur de l'assemblage de tige par la membrane et la semelle. Selon un mode de réalisation préféré, la membrane est le premier élément fixé à l'assemblage de tige, de manière à ce que cet assemblage compose un assemblage unitaire incluant la membrane, puis que l'assemblage de tige unitaire soit ultérieurement fixé lui-même à la semelle.
