Abstract

An outer sole for a golf shoe includes a plurality of cleats distributed along a forefoot area and a heel area. The cleats are integrated with the outer sole and extend from a surface of the outer sole that faces away from the shoe. The plurality of cleats includes at least a larger sized set of cleats and a smaller sized set of cleats. Such outer sole for a golf shoe gives good traction on the golf course but is also useable as a casual shoe off the golf course.

Claims

1. A sole for a golf shoe comprising:

a plurality of cleats integrated with the sole and distributed along a forefoot and heel area of the sole,

wherein the plurality of cleats is located on and extends from an outer surface of the sole facing away from the shoe,

the plurality of cleats comprising a first set of cleats and

the first set of cleats distributed along the forefoot area

the second set of cleats distributed along the heel area

each cleat comprises a circular center part and at least a first arm extending radially outwards from the circular center part of the cleat providing traction in a first direction, and at least a second arm extending radially outwards from the circular center part of the cleat providing traction in a second direction that is different from the first direction,

wherein a height of the center part does not exceed a height of the first and/or the second arm,

wherein the first and second arms delimit a generally planar ground contacting surface configured to support the shoe on the ground and to prevent penetration of the cleats into the ground, and

wherein the cleats are tapered in a direction away from the outer surface of the sole such that the arms extend further from the center of the cleat at a base portion extending at the outer surface of the sole than at the ground contacting surface.

2. A sole for a golf shoe according to claim 1, wherein a cross sectional shape of each cleat includes a circle.

3. The golf shoe according to claim 2, wherein the cleats have a tapering of between 60 and 85 degrees with a horizontal plane.

4. The golf shoe according to claim 2, wherein at least one cleat is offset from an adjacent cleat along the longitudinal length.

5. A sole for a golf shoe according to claim 1, wherein the first set of cleats and/or the second set of cleats are integrally molded with the outsole.

6. A sole for a golf shoe according to claim 1 where the first arm and the second arm are connected by an arch section.

7. A sole for a golf shoe according to claim 6, wherein the first and the second arm extend radially outwards from the arch section.

8. A sole for a golf shoe according to claim 1 wherein a larger set of cleats is surrounded by a smaller sized set of cleats.

9. The golf shoe according to claim 8, wherein the cleats having the smaller size substantially encircle the cleats having the larger size.

10. The golf shoe according to claim 9, wherein the cleats of the larger sized set of cleats have greater heights than the cleats of the smaller sized set of cleats.

11. A sole for a golf shoe according to claim 1 wherein the plurality of cleats shoe comprise an area between 25% to 40% of the outer surface of the sole.

12. The golf shoe according to claim 1, wherein the cleats are tapered in a direction from a bottom surface towards a base surface such that the cleats form conical cylinders.

13. The golf shoe according to claim 1, wherein a total area of the ground contacting surfaces of the cleats comprises about 25% to about 40% of a total area of the outer surface of the sole.

14. The golf shoe according to claim 1, wherein the cleats are arranged in transverse rows along a longitudinal length of the sole;

and wherein all of the cleats of at least one transverse row of cleats in the heel area have smaller heights than all of the cleats of at least one other traverse row in the heel area.

15. The golf shoe according to claim 1, wherein the forefoot of the sole has more cleats than the heel area of the sole.

16. The golf shoe according to claim 1, wherein the forefoot includes a ball area and a toe area, the ball area and the heel area having cleats that are substantially equal in height.

17. The golf shoe according to claim 1, wherein the sole has a thickness of about 0.098 inch to about 0.118 inch.

18. The golf shoe according to claim 1, wherein the sole is constructed from a material selected from the group consisting of thermoplastic polyurethane and polyurethane and rubber.

19. The golf shoe according to claim 1, wherein the cleats of the plurality of cleats extend from the outer surface at heights selected from the group consisting of 0.079, 0.118, and 0.197 inch.

20. The golf shoe according to claim 1, wherein each cleat of the plurality of cleats has the shape of a conical cylinder.

21. The golf shoe according to claim 1, wherein a cleat density of the sole is between about 0.25 and 0.60.

22. The golf shoe according to claim 1, wherein a ratio of a length of the first arm to a diameter of the center part is about 1.6.

23. The golf shoe according to claim 1, wherein a ratio of the lengths of the first and second arms to a diameter of the center part is about 1.6.

24. The golf shoe according to claim 1, wherein a length of the first and second arms is greater than or equal to a height of the cleat.

25. The golf shoe according to claim 24, wherein the length of the first and second arms is about twice the height of the cleat.
