Improved dorsiflexion shoe

Abstract

A high performance dorsiflexion shoe has a sole and a constraining device above the metatarsal-phalangeal joint. The sole has a ground-contacting surface, a forefoot region, a midfoot region and a heel portion. The forefoot region is made of a high density material, and has a thickness, measured in a direction perpendicular to the ground-contacting surface of the sole, greater than the thickness of the heel portion, thereby defining a characteristic angle of declination from the forefoot region to the heel portion. The constraining device substantially constrains a wearer's metatarsal-phalangeal joints from movement when exercising. The forefoot region has a curved form defined so as to further minimize flexion of the metatarsalphalangeal joint.

Description

technical field [0001] This invention relates to shoes, and more particularly to recreational and athletic shoes that promote dorsiflexion. Background technique [0002] In a standard shoe, the metatarsophalangeal joint remains in a flexed position when the shoe is taken off and cannot generate any energy during jumping and only a very small amount during running because the shoe does not is straight, any return energy is too small, too late, to have an effect on the performance of the shoe. Thus, the energy used is lost and does nothing to help improve jumping or running. Over the years, dedicated track and field shoes have advanced in that these shoes have begun to have relatively stiff midsoles. [0003] However, general athletic shoe manufacturers seem to be moving toward making these running shoes more flexible at the metatarsophalangeal joints by increasing the flexibility of the materials used in manufacture or changing the mechanism of the midsole (eg, incorporatin...

However, the shoe's 10-degree slant and particularly awkward appearance limit its marketability and usefulness to all but professional athletes.
