AI Technical Summary

Benefits of technology

This solution provides a more permanent correction by shifting the calcaneus medially, which elevates the foot and redistributes weight, reducing pronation and promoting better bipedal balance, similar to the evolutionary development of human bipedalism, without the need for external orthotics.

Problems solved by technology

An early problem with bipedalism was the upper leg and torso pushing the calcaneus towards the lateral.
This can result in a foot correction that is similar to non-corrective solutions already in place for over-pronation.

Embodiment Construction

[0024]Similar to the evolutionary journey to human bipedalism devices of the invention apply compression and tension, push and pill to bring about changes to the overpronator's foot. Changes and corrections to the foot are achieved over time by footwear of the invention. The invention corrects the overpronator's foot by moving the rearfoot medially and foot portions forward of it laterally. Shown in FIG. 1, is line 282 with arrowhead 282A pointing the direction of the foot correction. Along 282 is rearfoot arrowhead 283 pointing the medial direction of vector force on the overpronator's foot. On the lateral side of the foot medial pushing vector force 283 pushes the forefoot 284 laterally with a twisting on or about 285 in the midfoot. The vector force of footwear pushing the rear of the calcaneus to the medial interrupts the usual forward foot gait. The medial vector force also pushes forward along line 282 engaging a twist on or about point 285 not usual to the overpronator's gait...

Abstract

Overpronation of a foot is limited and corrected by a footwear article that acts on a foot in motion to act in relation to foot stepping by use of vertical restraints to move the calcaneus bone in a medial direction and shift pressure of the stepping foot and pull the first metatarsal laterally and shifting pressure off the first medial side to its lateral side.
