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.
Claims15
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 toe portion projection having a generally rectangular cross-section and extending from said sole at a location corresponding approximately to an end of a distal hallux of the foot, said first toe portion projection being disposed so that a face thereof forms an angle of 75°˜90° with respect to the longitudinal line of the foot;
- a second toe portion projection having a generally rectangular cross-section and extending from said sole at a location corresponding approximately to an end of a second distal phalanx of the foot and adjacent to the distal hallux, said second toe projection being disposed so that a face thereof forms an angle of 60°˜90° with respect to the longitudinal line of the foot;
- a first metatarsal head projection having a generally rectangular cross-section and extending from said sole at a location relatively frontward of a first metatarsal head of the foot, said first metatarsal head projection being disposed so that a face thereof forms an angle of 45°˜90° with respect to the longitudinal line of the foot;
- a stepping portion projection having a generally rectangular cross-section and extending from said sole at a location corresponding approximately to a third proximal phalanx of the foot, said stepping portion projection being disposed so that a face thereof forms an angle of 30°˜60° with respect to the longitudinal line of the foot;
- and
- a fifth metatarsal head projection having a generally rectangular cross-section and extending from said sole 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, said fifth metatarsal head projection being disposed so that a face thereof forms an angle of 50°˜80° with respect to the longitudinal line of the foot.
