METHOD OF FORCED SHOE VENTILATION Russian patent published in 2009 - IPC A43B7/06 A43B13/14 

FIELD: household goods and personal effects.

SUBSTANCE: atmospheric air is pumped through the system of horizontal elastic channels available in the shoe sole. They are placed in the cellular layer and do not interact with each other. While walking, the rear part of the leg heel interacts with the support surface of the front part. Then the sole contact with the surface moves to the toe part. At the same time, the load moves subsequently from heels to toe. The elastic channels of minor diameter of the cross section are deformed and blocked under the gravity effect. It helps to push air from hell to toe part of the show. The channel section diameter does not exceed 1.5-2.0 mm. Pressure is increased in the inner shoe volume resulting in air and water steam release through the natural slots between feet, inner surface of shoe top and toe material. The same action is repeated at each step, i.e. the system of elastic, horizontal channels is represented with a pump, which pumps atmospheric air into the toe part of the shoe.

EFFECT: more comfortable shoes, improved hygienic properties due to atmospheric air pumping through the toe shoe part.
