A running shoe having an outer sole and a midsole. The midsole comprises a forefoot portion, an arch portion and a heel portion all formed of a resilient material having a first durometer sufficiently low to provide good cushioning and impact absorption. Rear foot stabilization means in the form of a mass of resilient material is located and confined within the midsole adjacent the medial side of the heel portion. The durometer of the stabilization means is higher than the durometer of the midsole to provide resistance to compression at the medial side of the heel portion, thereby lessening the tendency of the shoe to overpronation. In one embodiment, the stabilization means comprises plural plugs confined fully within the midsole. In another embodiment, the stabilization means extend through the outsole and into the insole.
