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.

Claims

1. A sole for a spiked track-and-field shoe comprising:

a plurality of spike pins,

a wrap-up portion extending, via a coupling portion, from a leading tip of a toe region of a sole proper, and

multiple skid-preventing protrusions fixed onto the toe region of the sole proper, the coupling portion, and the wrap-up portion perpendicular 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,

said skid-preventing protrusions being formed to extend past a line which connects a first row of the tips of the spike pins and the leading tip of the toe portion but not past the spike pins,

the wrap-up portion being affixed to a toe region of an upper portion of the spiked track-and-field shoe.

2. A sole for spiked track-and-field shoes according to claim 1, wherein the skid-preventing protrusions are formed integrally with and from the same material as the sole proper and the wrap-up portion.

3. A sole for spiked track-and-field shoes according to claim 1, wherein the skid-preventing protrusions are formed as separate units from the sole proper and the wrap-up portion, and integrally formed by insertion into the sole proper.

4. A sole for spiked track-and-field shoes according to claim 1, wherein the surface of each of the skid-preventing protrusions is coated with a synthetic resin film.
