Abstract
This forced ventilation system is composed basically by a plastic box located in the rear part of the sole connected with a flow-conveyor through one or more tubes 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, excluding this process.
