Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of PCT patent application serial number PCT / GB2014 / 000532, published as WO 2015 / 092352, titled “IMPROVEMENTS IN OR RELATING TO FOOTWEAR” and filed on Dec. 19, 2014, which claims priority to GB1412185.9, titled “Improvements in or Relating to Footwear” and filed on Jul. 9, 2014, which claims priority to GB1322629.5, filed on Dec. 19, 2013, and, the entire specifications of each of which are hereby incorporated by reference in their entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to footwear for humans and, more particularly, to an insole, inner sole or insert sole member therefor.[0004]2. Background to the Invention[0005]A fundamental requirement for footwear: boots, shoes, slippers and sandals alike is that they are comfortable to wear. A shoe, in simple terms, comprises a sole, which treads upon the ground or floor in use, an innersole, upon which t...

AI Technical Summary

Benefits of technology

The present invention relates to an improved insole design for shoes that can help disperse the weight of the body more evenly across the foot, reducing pain and burning during times of extended standing or walking. The insole has three layers—a first layer for the heel, a second layer for the ball of the foot, and a third layer for the phalanges. The second layer is chamfered towards the edge of the foot to provide better spinal alignment. The first and second layers are made of foam with different hardness ranges, and the third layer is a laminated layer of foam with an additional layer of harder foam. This design helps to make shoes more comfortable to wear and provides a potential solution for women and men who enjoy wearing fashionable footwear but have issues with the insoles in their shoes.

Problems solved by technology

Thus, the foot and body of the user of such shoes are subject to impressive forces when the heel strikes the ground.

This repeated, high-energy impact causes discomfort, not only in the heel of the foot, but is also transferred throughout the body of the user of such shoes.

Additionally, since the heel is elevated, the impact forces the foot forward in the shoe, jamming the toes against the front of the shoe to cause further discomfort.

This rapid onset-rate does not allow time for the ankle, foot and leg muscles to adapt to the impact.

This causes muscle and foot surface fatigue and increases vulnerability to twisting an ankle or other injuries.

This causes the entire anatomy of the forefoot to give way, leading to excessive pressure and chafing on the ball of the foot.

It often occurs in combination with excessive formation of callouses.

Other actions that bring on this pain include long periods of standing or walking in hard shoes and boots.

The carrying of too much body weight through obesity also places undue strain on the feet.

Foot pain is not restricted to metatarsalgia and many foot conditions are due to poor shoe fit.

This can give rise to painful feet.

However, not all of these systems truly provide relief from foot pain.
