Claims24
A shoe having therein a shoe sole in which there are provided a plurality of check valves for discharging air contained in an inside of the shoe said check valves being made of a resilient material and each provided with a microhole connecting the inside of the shoe with an outside, such valves being formed of a membrane provided with a concavity that has a concave surface directed towards a fixed insole inside said shoe and beneath which a hollow space or chamber is formed which communicates through a lower side of the membrane with the outside and a tread of the shoe.
A shoe having a shoe sole, said shoe sole separating an inside of said shoe from an outside of said shoe,
- wherein in said sole a plurality of circular check valves are provided for discharging air from the inside of the shoe,
- each of said check valves comprising
- a circular membrane having an upper central circular concavity, wherein a concave surface of the concavity faces upward towards the inside of the shoe,
- a lower central circular chamber, wherein a concave surface of the chamber faces downwards towards a tread of the shoe,
- a diaphragm or screen separating said upper concavity from said lower chamber,
- a pierced microhole in said diaphragm for connecting said upper concavity to said lower chamber,
- wherein said shoe further comprises an air permeable insole on top of said shoe sole,
- whereby a pressure exerted by a foot on the insole causes the air contained within the shoe to pass from said upper concavity to said lower chamber and to discharge to the outside of the shoe.
