Shoe with breathable and waterproof sole and upper

A shoe with a breathable and waterproof sole and upper, comprising:

• a breathable and waterproof sole and an assembly associated with said sole in an upward region;
• an external breathable upper, an internal lining, and a breathable and waterproof membrane located between said upper and lining;
• at least one partially perforated or breathable insole, which is joined at least to said upper and said breathable and waterproof membrane;
• and wherein
• said breathable and waterproof sole is at least partially overmolded on said assembly, said upper being provided with passages for passage during overmolding of said sole, toward said breathable and waterproof membrane, for a polymeric material, said passages being arranged substantially at a connecting region between said upper and said breathable and waterproof membrane, said sole being joined hermetically and peripherally to said assembly in said connecting region.

A shoe provided with breathable and waterproof sole and upper, comprising:

• a breathable and waterproof sole and an assembly, which is associated with said sole in an upward region;
• an external breathable upper, an internal lining, and a breathable and waterproof membrane located between said upper and lining;
• at least one partially perforated or breathable insole, which is joined at least to said breathable and waterproof membrane;
• a waterproof inshoe, which is at least partially perforated or breathable at a region of said sole that is assigned to vapor permeation, said inshoe being associated in a downward region with said insole, with a peripheral edge thereof completely overlapping a connecting region between said insole and said breathable and waterproof membrane so as to provide a peripheral seal, said upper adhering to said inshoe, said breathable and waterproof sole being connected hermetically and peripherally with said assembly only at said upper and at an exposed portion of said inshoe, while leaving free of connection a remaining central part that corresponds to the region assigned to vapor permeation.

A method for manufacturing a breathable and waterproof sole, comprising:

• injection-molding at least one perforated lower sole layer;
• arranging, inside a mold, a breathable and waterproof membrane element on said at least one perforated lower layer;
• arranging at least one breathable element on top of said breathable and waterproof membrane element;
• covering with an adhesive film a surface of said at least one breathable element that lies opposite said breathable and waterproof membrane element;
• overmolding a peripheral skirt on said at least one perforated lower layer and laterally to said at least one breathable element;
• and
• removing said adhesive film.
