Abstract

A sole structure can be used with an article of footwear and includes fins for minimizing spin of at least one foot during the backswing and downswing stages of a golf swing. The sole structure includes an outsole having a forefoot region, a heel region, and a midfoot region between the heel region and the forefoot region, a lateral edge, and a medial edge. The outsole includes an outsole body. At least one plate is disposed on the outsole body. The plate is made of a material that is harder than the material forming the outsole body. Further, the plate includes a plate body disposed on the outsole body and a plurality of fins extending from the plate body. The fins include a fin body and a gusset protruding perpendicularly from the fin body.

Claims

1. A sole structure for an article of footwear, comprising:

an outsole having a forefoot region, a heel region, and a midfoot region between the heel region and the forefoot region, a lateral edge, and a medial edge, wherein the outsole includes;

an outsole body made of a first material, wherein the first material has a first hardness;

a first plate, a second plate, and a third plate each disposed on the outsole body, wherein each of the first plate, the second plate, and the third plate is made of a second material, the second material has a second hardness, the second hardness is greater than the first hardness, the first plate is coupled to the outsole body at the forefoot region, the second plate is a one-piece structure that extends along the forefoot region, the midfoot region, and the heel region of the outsole, the first plate and the second plate are spaced apart from each other so as to define a curved groove, and each of the first plate, the second plate, and the third plate includes;

a plate body disposed on the outsole body;

a plurality of fins extending from the plate body, wherein at least two of the plurality of fins are parallel to each other, and at least one of the plurality of fins includes;

a fin body extending along a lateral direction, wherein the lateral direction extends between the lateral edge and the medial edge; and

a gusset protruding from the fin body, wherein the gusset extends substantially perpendicularly relative to the fin body in a longitudinal direction, and the longitudinal direction extends between the heel region and the forefoot region.

2. The sole structure of claim 1, wherein the second plate defines a plurality of openings between the plurality of fins.

3. The sole structure of claim 2, wherein the plurality of openings are slots that are arranged parallel to each other.

4. The sole structure of claim 3, wherein the third plate is coupled to the outsole body at the heel region.

5. The sole structure of claim 3, wherein the outsole extends along a central longitudinal axis, the second plate includes a forefoot plate portion, a heel plate portion, and a midfoot plate portion interconnecting the forefoot plate portion and the heel plate portion, and the midfoot plate portion is obliquely angled relative to the central longitudinal axis.

6. The sole structure of claim 5, wherein the outsole has a foremost edge between the lateral edge and the medial edge, and a rearmost edge between the lateral edge and the medial edge, and the curved groove extends from the foremost edge to the lateral edge.

7. The sole structure of claim 6, wherein the curved groove is a first curved groove, and the second plate and the third plate are spaced apart from each other so as to define a second curved groove, and the second curved groove extends from the medial edge to the rearmost edge of the outsole.

8. The sole structure of claim 3, wherein at least two of the plurality of fins of the second plate are spaced relative to each other along the longitudinal direction and the lateral direction.

9. The sole structure of claim 1, wherein the fin body is elongated along the lateral direction.

10. The sole structure of claim 1, wherein the gusset is elongated along the longitudinal direction.

11. An outsole for a sole structure, comprising:

an outsole body having a forefoot region, a heel region and a midfoot region between the heel region and the forefoot region;

a first plate, a second plate, and a third plate each disposed on the outsole body, wherein the second plate is a one-piece structure that extends along the forefoot region, the midfoot region, and the heel region of the outsole body, the first plate and the second plate are spaced apart so as to define a curved groove, and each of the first plate, the second plate, and the third plate includes;

a plate body disposed on the outsole body;

a plurality of fins extending from the plate body, wherein at least two of the plurality of fins are parallel to each other, and at least one of the plurality of fins includes;

a fin body extending along a lateral direction; and

a gusset protruding from the fin body, wherein the gusset extends substantially perpendicularly relative to the fin body in a longitudinal direction.

12. The outsole of claim 11, wherein the second plate defines openings between the plurality of fins.

13. The outsole of claim 12, wherein the openings include slots arranged parallel to each other.

14. The outsole of claim 12, wherein the first plate is coupled to the outsole body at the forefoot region of the outsole body.

15. The outsole of claim 14, wherein the third plate is coupled to the outsole body at the heel region.

16. The outsole of claim 14, wherein the outsole extends along a central longitudinal axis, the second plate includes a forefoot plate portion, a heel plate portion, and a midfoot plate portion interconnecting the forefoot plate portion and the heel plate portion, and the midfoot plate portion is obliquely angled relative to the central longitudinal axis.

17. The outsole of claim 14, wherein at least two of the plurality of fins of the second plate are spaced relative to each other along the longitudinal direction and the lateral direction.

18. The outsole of claim 11, wherein the fin body is elongated along the lateral direction.

19. The outsole of claim 11, wherein the gusset is elongated along the longitudinal direction.
