Abstract (en)
[origin: US4685224A] A foam latex insole includes a number of ribs on its undersurface. The ribs face the top-sole of a shoe when the insole is placed therein, and are formed of foam latex which is closed-pored and somewhat firmer than the foam latex which forms the continuous part of the insole. The ribs can be straight, curved or sharply bent, and form a labyrinth of ventilation channels between the top-sole of the shoe and the underside of the foot. The arrangement of the rib is such that a pumping effect is developed in response to pressure changes on the insole which promotes the exchange of air within the shoe to maintain a suitable environment for the feet.
