Abstract

Spiked shoes enable the wearer to kick the ground with a minimum loss of power. The spiked shoes have spikes secured to the toe and heel portions of the sole to extend across the longitudinal centerline of the sole. An additional spike is mounted to the sole at its intermediate portion between the toe and heel portions to extend across the fourth metatarsal of the wearer'"'"'s foot. While the wearer is walking or running, the additional spike bears the wearer'"'"'s weight at the root of the fourth toe. The wearer can thus kick the ground with a minimum loss of power. As a result, this spike cooperates with the spikes at the toe and heel portions to grip the ground firmly so that the wearer can kick the ground strongly even with the heels off ground.

Claims

1. A spiked shoe comprising:

a sole having a toe portion, a heel portion and an intermediate portion between said toe portion and said heel portion, said sole further having a longitudinal centerline, a front end at which said toe portion is located and a rear end at which said heel portion is located;

first and second plate-shaped spikes provided at said toe portion on both sides thereof, and a third plate-shaped spike provided on said toe portion between said first and second spikes so as to be substantially perpendicular to said centerline;

said third spike being located nearer to said front end than are said first and second spikes;

said first and second spikes extending obliquely inwardly toward said front end;

said first spike being provided substantially under a portion of the sole corresponding to the articulate capsule of the interphalangeal joint of the hallux;

fourth and fifth plate-shaped spikes provided at said intermediate portion on both sides thereof and a sixth plate-shaped spike provided at said intermediate portion between said fourth and fifth spikes so as to extend across a portion of the sole corresponding to the fourth metatarsal and so as to extend substantially perpendicular to said longitudinal centerline;

said sixth spike being located nearer to said rear end than are said fourth and fifth spikes;

said fourth and fifth plate-shaped spikes extending obliquely outwardly toward said front end and provided at a portion of the sole corresponding to the ball of the spiked shoe; and

a seventh plate-shaped spike provided at said heel portion so as to extend substantially perpendicularly to said centerline.

2. The spiked shoe of claim 1 wherein said first spike forms an angle of not more than 45 degrees with respect to the centerline of said shoe.

3. The spiked shoe of claim 1, wherein said heel portion further has a pair of plate-shaped spikes disposed on either side of said seventh plate-shaped spike.

4. A spiked shoe comprising:

a sole having a toe portion, a heel portion and an intermediate portion between said toe portion and said heel portion, said sole further having a longitudinal centerline, a front end at which said toe portion is located and a rear end at which said heel portion is located;

a first base plate mounted at said toe portion, a second base plate mounted at said intermediate portion and a third base plate mounted at said heel portion;

said first base plate having a rear edge which is arcuately convex over the entire length thereof;

said second base plate having a front edge which is arcuately convex over the entire length thereof and extends under a portion of the sole corresponding to the articulate capsules of metatarsophalangeal joints;

said first base plate having first and second plate-shaped spikes provided on both sides thereof, and a third plate-shaped spike which is substantially perpendicular to said centerline;

said third spike being located between said first and second plate-shaped spikes and nearer to said front end than are said first and second plate-shaped spikes;

said first and second plate-shaped spikes extending obliquely inwardly toward said front end;

said first spike being provided substantially under a portion of the sole corresponding to the articulate capsule of the interphalangeal joint of the hallux;

said second base plate having fourth and fifth plate-shaped spikes provided on both sides thereof and a sixth plate-shaped spike provided at said intermediate portion between said fourth and fifth spikes so as to extend across a portion of the sole corresponding to the fourth metatarsal and so as to extend substantially perpendicular to said longitudinal centerline, said sixth spike being located nearer to said rear end than are said fourth and fifth spikes;

said fourth and fifth plate-shaped spikes extending obliquely outwardly toward said front end and provided at a portion of the sole corresponding to the ball of the spiked shoe; and

a third base plate having a seventh plate-shaped spike provided at said heel portion so as to extend substantially perpendicularly to said centerline.

5. The spiked shoe of claim 4, wherein said first spike forms an angle of not more than 45 degrees with respect to the centerline of said shoe.

6. The spiked shoe of claim 4, wherein said heel portion further has a pair of plate-shaped spikes disposed on either side of said seventh plate-shaped spike.
