Plate for shoe sole, shoe sole, and method for enhancing force feedback efficiency of shoe sole

Abstract

Disclosed are a plate for a shoe sole, a shoe sole, and a method for enhancing force feedback efficiency of a shoe sole. A plate is disposed in a midsole of the shoe sole. The plate comprises a plate body, wherein the plate body is downwardly recessed at a region corresponding to metatarsophalangeal joints of a foot to form a recessed structure, and in a cross-section taken along a foot width direction, the recessed structure comprises at least one arcuate shape with an arch opening facing upward. The recessed structure is configured to deform as a forefoot transverse arch compresses during a period from after forefoot ground contact until before toe-off, thereby storing elastic potential energy. The recessed structure is configured to release the stored elastic potential energy during toe-off to provide rebound force feedback to the foot.

Dependencies are inferred from the claim text.
