Abstract:

An air heel configuration to be used in the construction of a shoe of any type, whether high-heel or flat heel, in which an inner heel portion is activated as the wearer steps downward to move a spring-loaded plunger upward, opening an outlet ball valve, forcing air into a pocket in the inner sole, the air being pushed through ventilation apertures in the toe air, thus cooling the feet. As the heel of the wearer is raised, the outlet ball closes and the intake ball opens, the spring-loaded plunger moves downward, the outlet all closes and the intake ball opens, creating enough force to draw air into the air chamber within the inner heel portion.
