A vapor-permeable shoe comprising the following combination of elements: a vapor-permeable upper (11) associated with a vapor-permeable or perforated lining (12); a tread sole (13) made of perforated elastomer; a mid-sole, comprising at least one membrane (15) made of waterproof and vapor-permeable material associated with a lower protective layer (16) made of a material resistant to hydrolysis, the layer being water-repellent, vapor-permeable and/or perforated; a vapor-permeable or perforated insole (17); a vapor- permeable or perforated filler (19) layer arranged between said insole and said membrane. The membrane is associated and sealed, at its edge regions, to a pre-molded insert (14) which is suitable to form a perimetric support for the membrane both during assembly and during use.

L'invention concerne une chaussure perméable à la vapeur comprenant la combinaison suivante d'éléments; une tige perméable à la vapeur (11) associée à une doublure perméable à la vapeur ou perforée (12); une semelle d'usure (13) fabriquée en élastomère perforé; une semelle intercalaire comprenant au moins une membrane (15) en matériau résistant à l'eau et perméable à la vapeur associée à une couche inférieure de protection (16) formée d'un matériau résistant à l'hydrolyse, hydrofuge, perméable à la vapeur et/ou perforé; une semelle (17) perméable à la vapeur ou perforée; une couche de remplissage (19) perméable à la vapeur ou perforée disposée entre ladite semelle et ladite membrane. La membrane est associée et soudée, sur ses parties latérales, à un élément d'insertion (14) préalablement moulé, destiné à former un support de la membrane sur son périmètre pendant l'assemblage et l'utilisation.
