Foot membrane

Abstract

The present invention is a non-woven, transparent, foot membrane that helps provide comfort and support for the foot during high-heel shoe wear. The device comprises a self-supporting membrane that flexes, stretches and conforms to the shape of the foot, or the portion of the foot in contact with the membrane, when worn. The device has different thicknesses throughout its structure. Preferably, the parts of the invention at and around the major points of contact on a foot when in a high-heeled shoe, e.g., the mid-foot plantar surface, the toes (except the big toe) and the upper foot/ankle, are thicker than the other portions of the device. The device around the forefoot, the big toe, and the heel, is comprised of a plurality of layers of membrane material and gel-like material.

Problems solved by technology

Adverse effects of high-heel shoe wear is commonly experienced by people, typically women, in the form of general pain and discomfort and more prevalent foot problems.

Regular high-heeled shoe wear is a known cause to common foot problems such as, for example, skin irritation, blisters, skin stiffening, calluses, plantar forefoot pain at the forefoot, and metatarsalgia.

The Ko et. al. study concludes that the force that the ST endures at a state of maximum compressibility cannot be properly distributed by the natural plantar ST cushioning systems of the foot and can possibly lead to internal, plantar ST strain and damage.

Thus, the shear displacement of the plantar ST between the fourth and fifth metatarsal heads may lead to the callused skin typically found at a women's lateral forefoot and while the reduction of pressure forces are the main concern for the comfort of the medial forefoot, the lateral forefoot at the fourth and fifth metatarsal heads could be more vulnerable to increased shear forces.

Generally, the lower the denier, the sheerer the appearance and the more fragile the woven makeup of the product.

Athletic socks provide performance features not found in hosiery but are too bulky, thick, and opaque to be a viab
