Shoes - a new design

Abstract

A new design, applicable to most shoe types, having isolated, compressible rubber cushions as the only contact points with the ground. These cushions, usually 4 in number, are attached at only key points to an overlying flexible skeleton, made of a durable but bendable support structure. The ‘skeleton’ in turn is affixed to an overlying compressible ‘mattress’. This entire structure, consisting of compressible mattress, skeleton, and cushions duplicates the arch of the foot. Under the force of walking, running, etc. the rubber cushions will compress to absorb the force of the step. The overlying skeleton will also absorb energy by bowing convex downward at the toes, middle, and heel of the foot. Similarly the air space of the overlying mattress will also be compressed, absorbing pressure. Upon lifting the foot, the opposite actions will occur, releasing energy in an upward and forward direction, and thereby both lifting and propelling the foot.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a novel contact surface and support structure for a shoe. Shoes are almost universal apparel, worn for both appearance and function. This varies from walking, running, jumping, etc. and are used by both athletes and amputees. This invention seeks to enhance and complement the normal structure and function of the foot, rather than merely surround it in a box. [0002] The human foot is a dynamic structure intended to contact the found at predominantly two areas—the heel (talo-calcaneous) and the metatarsal-phalangeal joints (MT) and metatarsal heads. These structures are strongly formed and well supported by ligaments, tendons, and connective tissue. In contrast the toes (phalanges) and metatarsals (M) are lightweight, and weekly formed and protected. They are easily bruised, sprained, and broken. [0003] A traditional shoe provides some arch support, but transmits force to both the toes and metatarsal areas in a crushi...

AI Technical Summary

Benefits of technology

[0006] This novel shoe design is lighter in weight that the traditional, and also less expensive. The compressible rubber cushions are replaceable, thereby creating ‘reusuable shoes.’ Replacement should rarely be needed, as the underlying contact surface of the cushions is very sturdy, The contact cushions can be scored or imprinted on the bottom, maximizing traction or other functions. The cushions are screwed into the above skeleton, or possibly snapped with female and male portions, emphasizing reusability. The form of the cushions may vary to serve different functions—as tennis, basketball, running, walking. etc.

[0007] The skeleton is structured of either polyethylene, lightweight metal, plastic, polyvinyl, composite, etc. Its form is perforated in the center, or potentially could be constructed in a ‘rebar’ type structure. This structure will be durable, but also allows bendability in the center to maximize comfort and efficiency.

[0008] The invention allows great variety of the ‘foot cover’, providing both comfort and attractive design.

Problems solved by technology

Held has personally experienced the frustrations of currently available shoes, providing health care to many patients with foot and leg problems, diabetes, obesity, circulatory and neurological problems.
