Sole for a shoe and related methods

Abstract

A striking surface of a sole for a shoe comprises a central transition zone having a centerline extending substantially from the front of the sole to the rear of the sole, the central transition zone dividing the striking surface of the sole into a medial portion and a lateral portion. The medial portion of the striking surface is disposed at a first angle of inclination with respect to a support surface. The lateral portion of the striking surface is disposed at a second angle of inclination with respect to the support surface. The first angle of inclination may decrease along a length of the sole, from a front of the central transition zone to a rear of the central transition zone. The second angle of inclination may increase along a length of the sole, from a front of the central transition zone to a rear of the central transition zone.

Description

INTRODUCTION[0001]The present teachings relate to a sole for a shoe. In particular, the present teachings relate to a sole for a shoe that facilitates a more natural motion of the foot and thus enhances body performance.BACKGROUND[0002]The muscles of the leg and foot are designed to work best when moving on a naked foot. Warriors 3000 years ago wore flat-soled shoes. Indeed, up to the 15th century, shoes remained flat-soled, providing good balance and allowing the foot to work through its wide and opposed ranges of biomechanical movements. By the 16th century, some shoes had heels added to make people appear taller. However, up to the 1800's most shoes had flat soles, no cushioning, no arch support, no heels and no motion control support.[0003]In 1844, Charles Goodyear fused rubber with canvas and leather. The first rubber-soled sport shoe was sold in 1850 and the first running spikes in 1852. In 1880 tennis shoes were produced as a flat rubber sole vulcanized to canvas. Reebok, for...
