ABSTRACT:
A sole for spiked track-and-field shoes has a wrap-up portion which extends via a coupling portion from a leading tip of a toe region of the sole proper. Multiple skid-preventing protrusions are fixed onto the toe region of the sole proper, the coupling portion, and the wrap-up portion in a perpendicular manner to the toe region of an underneath part of the sole, a surface of the coupling portion, and a surface of the wrap-up portion, respectively. The skid-preventing protrusions are formed higher than a line which connects the first row of the tips of the spike pins and the tips of the toe portion but lower than the spike pins.
