Abstract:
1. A waterproof and vapor permeable sole for shoes, comprising: a lower element made of plastic material, on which a tread provided with a plurality of through holes is formed; a membrane which is impermeable to water and permeable to water vapor and is arranged above said lower element so as to be superimposed on said through holes, said membrane being joined perimetrically and hermetically to at least one component of the sole so as to avoid rise of liquids through said sole; vapor-permeable or perforated means for protecting said membrane, which are arranged below said membrane so as to be superimposed on the area of said holes, wherein said means for protecting said membrane comprises individual vapor-permeable or perforated protective elements, each arranged so as to block a corresponding said through hole, said lower element forming, for each of said through holes, an undercut region for preventing downward extraction for each of said protective elements, and said membrane overlaps said through holes and is joined perimetrically and hermetically to the lower element to form a single perimetric seal.
