ABSTRACT:
This invention is a track shoe comprised of an upper, an outsole and a spike plate. The outsole, made of an elastic material, has a bottom surface similar to the bottom surface of the spike plate. The bottom surface of the outsole, in addition, has spike receiving sockets where plastic spikes fit in and attach a detachable spike plate. The spike plate has seven apertures to allow for the insertion of seven plastic spikes which hold the spike plate to the outsole. The spike plate can be replaced by exchanging spike plates. The plastic spikes are designed to be lighter and more cost effective than steel ones, yet as easy to replace by the use of a common spike wrench.
