A stabilizer which surrounds the heel area may be formed as a single piece which wraps around the heel area or may be formed of several pieces joined to form a frame. The stabilizer includes cells when viewed in vertical cross section which provide lightweight, stable cushioning to the foot along the periphery of the midsole. The cells may take a variety of geometric configurations.
