A lightweight flexible outer sole for an athletic shoe comprising:
- a base member formed of resilient material and having a heel section, an arch section, a forefoot section and a toe section, said base member having an upper surface for attachment to another member and a lower surface;
- a plurality of ridges for providing traction and cushioning extending downwardly from the lower surface of said base member and transverse to the lengthwise direction thereof, said ridges being spaced from one another in the lengthwise direction of said base member and separated by spaces, each of said ridges being of uniform width;
- a first lateral cleat at the lateral end of a plurality of said ridges, said lateral cleat integrally formed with said ridges;
- and
- a second lateral cleat between adjacent ridges in said forefoot section, said second lateral cleats and said ridges in said forefoot section being the same depth.
