Abstract

A traction element arrangement for a sole structure of an article of footwear is described. Traction elements of a first group are associated with a lateral side of the sole structure. Traction elements of a second group are associated with a medial side of the sole structure. Traction elements of the second group include multiple medial rotational traction elements that each have a plurality of individual traction elements arranged in a circular grouping. Each circular grouping is a different size to provide more or less rotational movement to the associated portion of the sole structure. In one embodiment, the shape of the traction elements corresponds to the shape of the circular grouping.

Claims

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

a first medial rotational cleat group including at least two first cleats each having a concave inner surface that cooperate to define a first circle pattern having a first radius;

a second medial rotational cleat group including at least two second cleats each having a concave inner surface that cooperate to define a second circle pattern having a second radius;

a first elongate stud disposed between the first medial rotational cleat group and the second medial rotational cleat group and including a first longitudinal axis extending from a medial side of the sole structure to a lateral side of the sole structure, the first longitudinal axis being spaced apart from the first circle pattern and the second circle pattern; and

a second elongate stud disposed between the first medial rotational cleat group and the second medial rotational cleat group and including a second longitudinal axis extending from the medial side of the sole structure to the lateral side of the sole structure, a circumference of one of the first circle pattern and the second circle pattern intersecting the second elongate stud.

2. The sole structure of claim 1, wherein the second radius is different than the first radius.

3. The sole structure of claim 1, wherein the first medial rotational cleat group and the second medial rotational cleat group are disposed within a forefoot region of the sole structure.

4. The sole structure of claim 3, wherein the first medial rotational cleat group is disposed between a toe end of the sole structure and the second medial rotational cleat group.

5. The sole structure of claim 4, wherein the second radius is smaller than the first radius.

6. The sole structure of claim 5, wherein the first elongate stud includes a first support member extending along the first longitudinal axis in a direction away from the first elongate stud and toward the medial side and the second elongate stud includes a second support member extending along the second longitudinal axis in a direction away from the second elongate stud and toward the lateral side.

7. The sole structure of claim 1, wherein the first medial rotational cleat group is disposed adjacent to a peripheral edge of the sole structure within a forefoot region of the sole structure and the second medial rotational cleat group is disposed between the first medial rotational cleat group and a midfoot region of the sole structure.

8. The sole structure of claim 7, wherein the first elongate stud and the second elongate stud are disposed closer to the lateral side of the sole structure than the at least two first cleats and the at least two second cleats.

9. The sole structure of claim 1, wherein the first elongate stud and the second elongate stud are disposed closer to the lateral side of the sole structure than the at least two first cleats and the at least two second cleats.

10. An article of footwear incorporating the sole structure of claim 1.

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

a first medial rotational cleat group including at least two first cleats each having a concave inner surface that cooperate to define a first circle pattern having a first radius;

a second medial rotational cleat group including at least two second cleats each having a concave inner surface that cooperate to define a second circle pattern having a second radius;

a first elongate stud disposed between the first medial rotational cleat group and the second medial rotational cleat group and including a first longitudinal axis extending from a medial side of the sole structure to a lateral side of the sole structure, the first elongate stud spaced apart from the first circle pattern and the second circle pattern; and

a second elongate stud disposed between the first medial rotational cleat group and the second medial rotational cleat group and including a second longitudinal axis extending from the medial side of the sole structure to the lateral side of the sole structure, the second elongate stud disposed at least partially within one of the first circle pattern and the second circle pattern.

12. The sole structure of claim 11, wherein the second radius is different than the first radius.

13. The sole structure of claim 11, wherein the first medial rotational cleat group and the second medial rotational cleat group are disposed within a forefoot region of the sole structure.

14. The sole structure of claim 13, wherein the first medial rotational cleat group is disposed between a toe end of the sole structure and the second medial rotational cleat group.

15. The sole structure of claim 14, wherein the second radius is smaller than the first radius.

16. The sole structure of claim 15, wherein the first elongate stud includes a first support member extending along the first longitudinal axis in a direction away from the first elongate stud and toward the medial side and the second elongate stud includes a second support member extending along the second longitudinal axis in a direction away from the second elongate stud and toward the lateral side.

17. The sole structure of claim 11, wherein the first medial rotational cleat group is disposed adjacent to a peripheral edge of the sole structure within a forefoot region of the sole structure and the second medial rotational cleat group is disposed between the first medial rotational cleat group and a midfoot region of the sole structure.

18. The sole structure of claim 17, wherein the first elongate stud and the second elongate stud are disposed closer to the lateral side of the sole structure than the at least two first cleats and the at least two second cleats.

19. The sole structure of claim 11, wherein the first elongate stud and the second elongate stud are disposed closer to the lateral side of the sole structure than the at least two first cleats and the at least two second cleats.

20. An article of footwear incorporating the sole structure of claim 11.
