Abstract

A shoe is disclosed utilizing interrelated structural elements for dynamic cooperation with the human foot to reduce the likelihood of injury or deterioration during strenuous activity or over extended intervals of time, while affording greater comfort and ease of motion. The shoe bottom includes a sole above which a platform provides a plurality of cylindrical spaces that receive plugs in loose telescopic relationship, to define spaces for coil springs. So mounted, the coil springs are stabilized against lateral displacement. Above the platform, the shoe bottom is affixed to an upper shoe covering to define a space for the wearer's foot. At the rear quarter of the shoe upper, a heel cup stabilizes the heel of a wearer's foot against lateral, medial, or posterior displacement as well as to distribute the forces on the heel reducing the likelihood of trauma. As disclosed, the heel cup comprises an air-containing bladder to provide a cushioned wedge which prevents excessive extension of the limb while allowing effective pronation. Finally, a ridge is provided at the inner sole for gripping engagement by the toes (sulcus) for more effective use of the forward portion of the foot.
