Abstract (en)
This forced ventilation system is composed basically by a plastic box (11) located in the rear part of the sole connected with a flow-conveyor through one or more tubes (17,18) joined to one or more pneumatic valves. Its essential role is founded on the principle that its compression every step generates a forced ventilation internally the sole and consequently internally the shoe. This system can be closed by a special cap (23), excluding this process. <IMAGE> <IMAGE>
