Shoe sole with compressible protruding element

Abstract

A footwear sole assembly with at least one compressible protruding element extending downwardly beyond the bottom surface of the outsole, the at least one protruding element providing a natural instability to a wearer when the sole assembly initially contacts a supporting surface. The at least one protruding element is a three-dimensional structure formed of a substantially solid elastomeric material. In another embodiment, the at least one protruding element may also protrude upwardly beyond the sole assembly in such a manner that the wearer's foot can apply pressure to the top portion of said at least one protruding element.

Description

BACKGROUND OF INVENTIONThe present invention relates to a footwear construction and, more particularly, to a footwear sole construction with one or more compressible protruding elements or elastomeric ball-shaped objects.Numerous attempts have been made over the years to incorporate into a shoe means for providing improved cushioning and resiliency to the shoe. These attempts have included using air cushioning systems such as air cavities or air bladders disposed within the sole of a shoe. However, the conventional cushioning systems only give wearers comfort by cushioning effect.On the other hand, physical exercise of the foot through ranges of motion and physical stretching have provided for many a modicum of relief. Manual manipulation of an elastomeric member, for example, a rubber ball or stress ball, has proven beneficial to some for muscle toning and / or relief of stress. Furthermore, the benefits of exercising or sitting on a resilient ball, for example, sitting on a fitness ...
