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.
