Cambered sole

a technology of cambered soles and soles, which is applied in the field of cambered soles, can solve the problems of affecting the fit of the shoe, unable to allow the foot to flex and expand in the transverse and longitudinal planes, and the sole to conform, so as to improve the efficiency of the athlete and prevent injury

AI Technical Summary

Benefits of technology

The patent text is discussing the need for a shoe that provides better flexion and support for the foot during loading and unloading, which can help prevent injury and improve athletic efficiency. The goal is to create a shoe that offers adequate cushioning and protection for the foot while still giving a more natural, adaptive flexion.

Problems solved by technology

Traditional athletic footwear generally has a midsole that has substantial thickness in the heel and forefoot which does not allow the sole to conform to the wearers foot while it is flexed and torqued during the gait cycle.
This has a negative impact on the fit of the shoe and does not allow the foot to flex and expand in the transverse and longitudinal planes.
As a result, miminal-type products generally require very thin sole elements with very little support provided to the wearer.

Embodiment Construction

[0038]The invention described herein relates to footwear, and more particularly to soles, and components thereof, providing a flexible cambered profile for at least a portion of the sole.

[0039]The sole components described herein may form an insole, midsole, and / or outsole of a shoe, or form a sole element for integration into an insole, midsole, and / or outsole of the shoe (e.g., through bonding to, and / or mechanical attachment to, another midsole element). The sole components can be manufactured from any appropriate method and system, as is known in the art. In one embodiment, for example, a sole, or a component therefor, can be manufactured from a polymeric material that is molded (e.g., expansion molded or compression molded) to form a finished part.

[0040]Polymeric material for use in the manufacture of the sole components may include, or consist essentially of, polymers, elastomers, thermoplastics, and / or thermosets. For example, the polymeric material may be ethylene vinyl acet...

Abstract

The invention relates to shoes including sole elements having a cambered profile. An example sole element includes a midsole having a heel portion, a midfoot portion, and a forefoot portion, the midfoot portion including a longitudinal arch including a medial longitudinal arch portion and a lateral longitudinal arch portion, wherein the longitudinal arch is at least partially elevated above a ground surface in an unloaded condition and deforms towards a ground surface and elongates longitudinally in a loaded condition.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 61 / 792,691, filed Mar. 15, 2013, the disclosure of which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to the field of footwear, and more particularly to shoe soles, and components thereof, having a cambered profile.BACKGROUND OF THE INVENTION[0003]Traditional athletic footwear generally has a midsole that has substantial thickness in the heel and forefoot which does not allow the sole to conform to the wearers foot while it is flexed and torqued during the gait cycle. This has a negative impact on the fit of the shoe and does not allow the foot to flex and expand in the transverse and longitudinal planes. Minimal athletic footwear with thinner midsole profiles have been designed to try to accommodate this flexion and torsion and to allow the shoe to expand in the tra...
