A track shoe with an improved sole is disclosed. The sole includes a plate formed of a first material which extends along substantially the entire length of the shoe. A plurality of traction cleats are permanently attached to the plate and are formed of a second material having a hardness less than the first material. A plurality of spike fasteners are attached to the forepart portion of the plate and a pair of lateral traction extensions are formed integral with the plate and extend upwardly therefrom adjacent to and upwardly of the fifth metatarsal-phalanges joint. The lateral traction extensions are separated by a gap. First, second and third flex grooves are formed in the plate to enhance the flexibility of the plate along the grooves. The first and second flex grooves extend generally parallel to a line between the first and second metatarsal-phalanges joints. The third flex groove extends substantially parallel with a line extending along the second through fifth metatarsal-phalanges joints.
