Ventilated footwear

Ambulatory activated footwear with a cooling system comprising:

• footwear having a permeable top side, an insole and outer sole with an incorporated heel having a bottom surface;
• a plurality of perforated air channels communicating with the interior of said footwear formed in the insole of said footwear, such channels connected to a common air passage;
• a compressible bellows pump means located in a cavity in said heel, said pump means having its inlet connected to such common air passage in said footwear and its outlet vented to the atmosphere;
• a piston sleeve located below said bellows pump means and fixedly received in said heel;
• a reciprocating ball piston means located in said sleeve, the ball of said ball piston means having a portion thereof extending beyond the bottom surface of the heel when said heel is not in contact with a walking surface and said ball operable to actuate said pump means when said heel of said footwear contacts a walking surface driving said ball into said sleeve;
• a retaining ring received at the bottom end of said sleeve operable to retain said ball in said sleeve when said heel is not in contact with a walking surface;
• and
• valve means located such common air passage operable to restrict air flow to a single direction therein whereby said pump means can only exhaust air from the interior of said footwear and second valve means in the outlet of the said pump means operable to prevent air from the exterior of said footwear form entering said ball piston means.
