ABSTRACT:
By analyzing the force which acts during actual running from a bio mechanical perspective and determining the most preferable positions of spikes on the shoe sole, spikes can be arrayed only in necessary positions and not in unnecessary positions so as to further lessen weight and also provide rigidity to the region wherein spike placement is voided, so as to deal with unwanted flexion of the shoe sole. A shoe sole for spiked track-and-field athletic shoes has spikes located only in positions corresponding to the heads of the metatarsals and in positions corresponding to the distal phalanxes. The shoe sole regions between the spikes arrayed in positions corresponding to the heads of the metatarsals and in positions corresponding to the distal phalanxes are provided with an appropriate rigidity.
