A shoe outsole includes an outer member with an inner heel region. An inner member is located in the inner heel region and includes a ground-contacting surface. The inner member has a softer durometer than the outer member. The inner member contains a liquid or gas. The outer member includes a back wall having a rounded contour extending smoothly between a horizontal plane and a vertical plane. A plurality of grooves are defined in a lower forefoot region and an upper forefoot region of the shoe outsole. The lower forefoot region includes a plurality of ridges interdigitated with the grooves. At least one of the grooves extends toward a front edge of the shoe outsole beyond a ground-engaging portion of the lower forefoot region when flatfooted.
