Benefits of technology

[0007]A sole for use in footwear comprising a foot cradle for contacting the user's foot and a rocker bottom for engaging a walking surface, said sole extending beneath the heel through the ankle / sub-talar complex and metatarsal head of a user, said rocker bottom being characterized as having a convex lower surface beneath the ankle / sub-talar complex curving upwardly towards said heel and said metatarsal head. The present invention supports the four major arches of the foot, eliminates step shock, controls frontal plane motion, transfers motion from the heel to ankle at the sub-talar joint and ankle to forefoot at the metatarsal joint.

Problems solved by technology

Although there have been a plethora of soles and orthotic inserts alleged to improve the acts of walking, standing, exercising and load bearing in order to provide decreased stress and skeletal alignment, there has been no system that can be characterized as representing a paradigm change in foot function from resistance to acceleration and from motion control to motion enhancement.
Next, the downward ankle motion through the sub-talar joint creates fatigue.

Embodiment Construction

[0014]As noted previously with respect to the discussion of FIG. 1, the typical walking motion in prior footwear on hard flat surfaces creates impact shock and rapid downward flexion of the foot as body weight passes from heel to toe through the sub-talar, ankle, and mid-tarsal joints until the forefoot impacts and pushes off through the weight bearing metatarsal bones. The most common heel, ankle, and forefoot problems such as heel spurs, plantar fasciitis, ankle arthritis, tendonitis, metatarsalgia, capsulitis, sesamoiditis, bunions, hallux rigidus, and hammertoes are caused by walking on hard surfaces with a heeled shoe. Of primary concern is the recognition that prior footwear causes the bones of the foot and ankle to undergo greater impact and joint distortion than walking barefoot on soft surfaces.

[0015]The present invention can be more readily appreciated when considering FIG. 1 in conjunction with the depiction of human foot 30 of FIG. 2. FIG. 2 shows curved shapes I, II, an...

Abstract

A sole for use in footwear that includes an upper surface for contacting the user's foot and a lower surface for engaging a walking surface. The sole extends beneath the heel through the ankle / sub-talar complex and metatarsal head of the user. The lower surface is characterized as having a convex lower surface beneath the ankle / sub-talar complex curving upwardly toward the heel and metatarsal head.

Description

TECHNICAL FIELD[0001]The present invention involves a sole capable of being incorporated in a variety of footwear applications including shoes, sandals and slippers (collectively referred to as “shoes”). When properly incorporated within a shoe, the present invention provides motion enhancement for the human foot to improve posture, comfort, support and to eliminate shock.BACKGROUND OF THE INVENTION[0002]Although there have been a plethora of soles and orthotic inserts alleged to improve the acts of walking, standing, exercising and load bearing in order to provide decreased stress and skeletal alignment, there has been no system that can be characterized as representing a paradigm change in foot function from resistance to acceleration and from motion control to motion enhancement. Traditional orthotic devices and shoes employing them use firm materials to support the foot and cushion materials for shock absorption that protect the foot from hard surfaces. Comfort is based on the c...
