Abstract

A breathable shoe including an upper assembly having a breathable upper, a membrane made of a material which is waterproof and breathable, and a sole made of perforated elastomer, which arc all mutually attached such that the membrane is arranged between the upper assembly and the sole. Further, the sole is sealed perimetrically to the membrane, in a manner to prevent moisture from entering into the upper assembly from the sole through the membrane, and to permit moisture to leave the inside of the upper assembly through the membrane and through the sole. In one preferred embodiment, the membrane is first attached to the upper assembly so that the upper assembly is a unitary upper assembly including the membrane, and such a unitary upper assembly is subsequently attached to the sole.
