Abstract
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.
