Abstract
A sole of a baseball spiked shoe has a toe portion projection, a first metatarsal head projection, a stepping portion projection, and a fifth metatarsal head projection provided at a fore foot portion at the bottom plane of the shoe sole, and a heel medial projection, a heel anterior projection, a heel posterior projection, and a heel lateral projection provided at the heel portion. Each projection is provided at an appropriate angle with respect to the longitudinal line of the foot.
Claims40
A sole of a spiked shoe having a plurality of projections at positions corresponding to the skeleton of a foot of an appropriate size for wearing the spiked shoe, said sole comprising:
- a first connecting collar secured to said sole, said first connecting collar including:
- a first toe portion projection having a generally rectangular cross-section and extending from said first connecting collar at a location corresponding approximately to an end of a distal hallux of the foot,
- a second toe portion projection having a generally rectangular cross-section and extending from said first connecting collar at a location corresponding approximately to an end of a second distal phalanx of the foot,
- a first metatarsal head projection having a generally rectangular cross-section and extending from said first connecting collar at a location relatively frontward of a first metatarsal head of the foot;
- and
- a second connecting collar secured to said sole, said second connecting collar including:
- a stepping portion projection having a generally rectangular cross-section and extending from said second connecting collar at a location corresponding approximately to a third proximal phalanx of the foot, and
- a fifth metatarsal head projection having a generally rectangular cross-section and extending from said second connecting collar at a location approximately between a proximal portion of a fourth proximal phalanx and a proximal portion of a fifth proximal phalanx of the foot.

- and
- a second connecting collar secured to said sole, said second connecting collar including:
- a stepping portion projection having a generally rectangular cross-section and extending from said second connecting collar at a location corresponding approximately to a third proximal phalanx of the foot, and
- a fifth metatarsal head projection having a generally rectangular cross-section and extending from said second connecting collar at a location approximately between a proximal portion of a fourth proximal phalanx and a proximal portion of a fifth proximal phalanx of the foot, and
- a heel connecting collar secured to said sole, said heel connecting collar including:
- a heel medial projection having a generally rectangular cross-section and extending from said heel connecting collar at approximately the medial side of a heel center of the foot,
- a heel posterior projection having a generally rectangular cross-section and extending from said heel connecting collar at approximately the posterior of the heel center, and
- a heel lateral projection having a generally rectangular cross-section and extending from said heel connecting collar at approximately the lateral side of the heel center;
- said heel medial projection being disposed such that a face thereof is substantially parallel to a longitudinal line of the foot;
- said heel posterior projection being disposed such that a face thereof is substantially perpendicular to the longitudinal line of the foot;
- and
- said heel lateral projection being disposed such that a face thereof forms an angle of 20°˜45° with respect to the longitudinal line of the foot.
