Air Ventilation Outsole

The present invention relates to an outsole. More particularly, the present invention relates to an air ventilation outsole which can facilitate an air ventilation in a shoe.

A conventional outsole of a shoe does not have any air ventilation function at all. Therefore, the sweat of the user will remain in the shoe. Thus the sweat may cause uncomfortable odor.

An object of the present invention is to provide an air ventilation outsole which can facilitate an air ventilation in a shoe.

In accordance with a preferred embodiment, an air ventilation outsole comprises a heel, a blind hole formed in the heel, a vent hole formed on the heel and communicating with the blind hole, and a ventilation pad disposed in the blind hole. The ventilation pad is made of plastic materials. The ventilation pad comprises a plurality of upper recesses, a plurality of lower recesses, a first breather hole formed on an upper portion of the ventilation pad, a second breather hole formed on the upper portion of the ventilation pad, a large number of reinforced ribs disposed in the ventilation pad defining a plurality of air chambers, a first rear aperture, a second rear aperture, a pair of first opposite lateral apertures, and a pair of second opposite lateral apertures. The first rear aperture and the second rear aperture communicate with the respective air chamber. The first opposite lateral apertures communicate with the respective air chamber. The second opposite lateral apertures communicate with the respective air chamber. A U-shaped plug device has a first plug and a second plug. The U-shaped plug device is made of plastic materials. The first plug has a first main body, a first center hole, and a first annular flange. The second plug has a second main body, a second center hole, and a second annular flange. The first annular flange is inserted in the second rear aperture. The second annular flange is inserted in the first rear aperture.

In accordance with another preferred embodiment, an air ventilation outsole comprises a heel, a blind hole formed in the heel, a first rear vent hole formed on the heel and communicating with the blind hole, a second rear vent hole formed on the heel and communicating with the blind hole, and a ventilation pad disposed in the blind hole. The ventilation pad is made of plastic materials. The ventilation pad comprises a plurality of upper recesses, a first breather hole, a second breather hole, and a plurality of lower posts. A U-shaped plug device has a first plug and a second plug. The U-shaped plug device is made of plastic materials. The first plug has a first main body, a first center hole, and a first annular flange. The second plug has a second main body, a second center hole, and a second annular flange. The first annular flange is inserted in the first rear vent hole. The second annular flange is inserted in the second rear vent hole.
