Abstract
A shoe includes a midsole with an anti-G-force heel capsule that nests in a corresponding aperture in the heel. The heel capsule interacts with an anti-torsion member, the rearmost portion of which lies proximate to the heel plug, and with an energy-efficient forefoot midsole section, thus providing a support and cushioning system that absorbs shocks associated with walking, and also prevents excessive pronation.

A shoe, comprising:
- an outsole, including a sole portion and a heel portion, the heel portion including an aperture therein having side walls;
- a midsole attached to the top of the outsole, the midsole including a heel capsule having side walls and extending into the aperture in the heel portion of the outsole, wherein the capsule's side walls are generally conformable to those of the aperture;
- and
- an anti-torsion member with a central axis lying in a complementarily shaped recess along the central axis of the midsole, the rear portion of the anti-torsion member lying proximate to the upper portion of the heel capsule, such member further including two integrally formed arms transversely disposed with respect to the central axis of the anti-torsion member, and extending towards the sides of the midsole;
- such midsole including an energy efficient forefoot section, nested within a higher density perimeter, adjoining the anti-torsion member.
