Abstract
The forefoot portion of a shoe bottom includes at least one independent open air cavity composed by complementing concave arcs found in the lower midsole and upper midsole. The upper midsole includes at least one ventilation hole for the passage of air to and from the wearer's foot. During compression of the shoe bottom, caused by the wearer's foot, the open air cavity forces air through the ventilation hole, and through the insole hole introducing air into the shoe interior.
