Abstract:
A shoe air flow system comprising:a shoe having a toe section, metatarsal section, longitudinal arch section, heel section, back section, bottom section and adapted to have a foot of a wearer disposed in the shoe for operating the air flow system; a heart pump disposed in the heel section for actuating the main supply of air throughout the system; a plurality of arteries for carrying air from the heart pump to the system, the plurality of arteries actuated by a pressure gradient caused by the downward thrust of the person's heel; a plurality of venous non-distensible unidirectional veins disposed about the periphery of the shoe return the air rearward therefore to be discharged to the atmosphere; an on-demand sieve plate is disposed on the back section as an access location for incoming air; the back section includes a pair of support panels, an interior support panel and an exterior support panel, the panels defining an air channel there between for carrying air to the heart pump; the lower ends of the panels are curved, the end of the exterior panel being stationary, the end of the interior panel having an isthmus type shape and positioned directly above the end of the exterior panel to create a valve, wherein the downward thrust of the wearer's heel causes the isthmus to close the valve and thereby shut the flow of air to the heart pump and subsequently cause the air in the heart pump to be propelled forward through the arteries.
