Abstract (en)
[origin: EP0714611A1] The ventilation comprises a compressible sealed chamber (1) in a flexible material constituted by a container with a cover. The cover consists of membranes forming non return valves allowing inlet and exhaust of air into the container in a single flow direction. The cover has a groove in its periphery into which the upper edge of the container is housed and sealed. The compressible chamber is encastred in an inner sole (14) which has on one face a network of air circulation channels (15) and holes (16). The channels communicate with the compressible chamber and the holes connect the channels to the internal sole opposite face. The container has at one end a flexible sloping tab (2') which lies on the wearing sole (20) and acts as a spring between this sole's upper surface and the inner sole lower face.
