ABSTRACT:
This invention relates to a spike shoe including a sole, a plurality of spike pins mounted thereupon and a resilient elastic material fixed with the sole, the resilient elastic material having such a thickness that each spike pin can be concealed therein, and including a plurality of holes in order to permit the spike pins to protrude from the resilient elastic material when the weight of human body is applied to the spike shoe, whereby the spike pins are forced into the ground. When the weight is removed from the sole, the spike pins are retracted into the resilient material leaving any mud which may have been stuck to the pins on the smooth bottom surface of the sole from which the mud may be easily removed.
