Abstract
A vapor-permeable shoe which includes an upper, a tread made of elastomer, shaped so as to form a plurality of domes whose convexity is directed toward the ground, each dome having at least one minute through slit which is normally closed due to the elasticity of the material and allows the outflow of a mixture of air and water vapor formed inside the shoe when the compression applied by the sole of the foot of a user generates an overpressure at the chambers formed internally by said domes, a vapor-permeable or perforated insole, and a waterproof and vapor-permeable protective membrane. The lower part of the upper, the tread and the membrane are perimetrically sealed in the regions where they join.

A vapor-permeable shoe, comprising:
- an upper;
- a tread made of an elastomer, said tread being fastened to said upper and being shaped so as to form a plurality of domes having a convexity directed toward the ground, each dome forming a chamber and having at least one minute through slit which is normally closed due to the elasticity of the material and allows outflow of a mixture of air and water vapor formed inside the shoe when compression applied by the sole of the foot of a user generates an overpressure at the chambers formed internally by said dome;
- a vapor-permeable or perforated insole;
- and
- a waterproof and vapor-permeable membrane interposed between said insole and said tread, the lower part of said upper, said tread and said membrane being perimetrically sealed in regions where said tread and said membrane are joined.
The vapor-permeable shoe, comprising:
- an upper;
- a tread made of an elastomer, said tread being fastened to said upper and being shaped so as to form a plurality of domes having a convexity directed toward the ground, each dome forming a chamber and having at least one minute through slit which is normally closed due to the elasticity of the material and allows the outflow of a mixture of air and water vapor formed inside the shoe when compression applied by the sole of the foot of the user generates an overpressure at the chambers formed internally by said domes;
- a vapor-permeable or perforated insole;
- a perforated intermediate element, said element being shaped so as to form, at a surface that is directed toward the tread, a plurality of conical raised portions, each of which is inserted in a corresponding chamber formed by a corresponding dome and closes said corresponding chamber when pushed and compressed by the sole of a foot of a wearer that rests thereon.
