Abstract

Zapato permeable a los vapores que comprende la siguiente combinación de elementos: -una pala permeable a los vapores asociada con un forro permeable a los vapores o perforado; -una suela exterior hecha de elastómero perforado; -una suela intermedia que comprende por lo menos una membrana hecha de material impermeable al agua y permeable a los vapores y que está asociada con una capa protectora inferior hecha de un material resistente a la hidrólisis, hidrófobo y permeable a los vapores y/o perforado; -una palmilla permeable a los vapores o perforada; -una capa de relleno permeable a los vapores o perforada dispuesta entre dicha palmilla y dicha membrana. La membrana está asociada y sellada, por sus zonas marginales, a un inserto premoldeado que es apto para formar un soporte perimétrico para la membrana tanto durante el ensamblaje como durante el uso.Vapor-permeable shoe comprising the following combination of elements: -a vapor-permeable upper associated with a vapor-permeable or perforated lining; -an outsole made of perforated elastomer; -a midsole comprising at least a membrane made of water-permeable and vapor-permeable material and associated with a lower protective layer made of a hydrolysis-resistant, hydrophobic and vapor-permeable and / or perforated material ; -a vapor-permeable or perforated insole; -a perforated or vapor permeable filler layer arranged between said insole and said membrane. The membrane is associated and sealed, by its marginal areas, with a pre-molded insert that is capable of forming a perimetric support for the membrane both during assembly and during use.
