<p>We have invented a new sole with a pumping action for the part of the shoe near the heel, inside a cylindric pump, connected with channels near the front part of the foot connected to the outside part of the sole, with a valve for the passing of air. Therefore giving life and automatic movement of respiration and compression for the circulation of air for the inner part of the footwear, resolving all problems due to the loss of the circulation of air.</p> |
