Breathable sole structure for footwear

Abstract

The instant invention is a breathable sole structure for footwear. The footwear sole structure includes an insole, an outsole, and a functional membrane system. The insole has an area with a plurality of holes therethrough. The outsole has an area with a plurality of holes therethrough. The functional membrane system has a microporous hydrophilic membrane and a microporous hydrophobic membrane. The insole and the outsole are bonded to each other, so that the functional membrane system is sandwiched therebetween; and furthermore, the functional membrane system is juxtaposed to said areas.

Description

FIELD OF THE INVENTION [0001] The instant invention relates to a breathable sole structure for footwear. BACKGROUND OF THE INVENTION [0002] Footwear, and in particular shoes, usually include two major components, a shoe upper and a sole. The general purpose of the shoe upper is to snuggly and comfortably enclose the foot. Ideally, the shoe upper should be made from an attractive, highly durable, comfortable materials or combination of materials. The sole, constructed from a durable material, is designed to provide traction and to protect the foot during use. The sole also typically serves the important function of providing enhanced cushioning and shock absorption during athletic activities to protect the feet, ankles, and legs of the wearer from the considerable forces generated. [0003] Many kinds of footwear, such as athletic shoes, everyday walking shoes, and work boots have the drawback of poor ventilation. The shoe upper and sole do not allow the foot to breathe. Since the foot...

AI Technical Summary

Benefits of technology

The invention is a shoe with a breathable sole structure. It includes an insole, outsole, and a functional membrane system. The insole and outsole have holes, and the membrane system has two layers: one is water-loving and the other is water-repelling. The membrane system is sandwiched between the insole and outsole and is in contact with the holes. This results in a shoe that allows air and moisture to flow through, keeping the foot cool and comfortable.

Problems solved by technology

Many kinds of footwear, such as athletic shoes, everyday walking shoes, and work boots have the drawback of poor ventilation.

The shoe upper and sole do not allow the foot to breathe.

Since the foot cannot breathe, perspiration cannot be removed.

The accumulation of perspiration can then promote the growth of bacteria, fungi and the like as well as the accompanying unpleasant odors and skin problems.
