Abstract

A sole structure for an article of footwear having an upper includes a midsole. The midsole may include a cushion and a chassis. The cushion extends from a forefoot region to a heel region of the sole structure. The chassis is disposed between a top side of the cushion and the upper. An outsole is mounted to a bottom surface of the midsole. The outsole includes a first outsole portion, a second outsole portion and a third outsole portion. The first outsole portion, the second outsole portion and the third outsole portion are spaced apart from each other so as to provide flexibility to the sole structure. The first outsole portion, the second outsole portion and the third outsole portion may be formed of a first material and a second material. The second material is more durable relative to the first material.

Claims (24)

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

a cushion including a series of lobes arranged from a forefoot region to a heel region along a medial side and a lateral side of the sole structure; and

an outsole having a first side attached to the cushion, a second side disposed on an opposite side of the outsole than the first side and defining a ground-contacting surface of the sole structure, a first outsole portion having a substantially U-shape and including a first medial leg and a first lateral leg, and a second outsole portion spaced apart and formed separately from the first outsole portion such that the first outsole portion and the second outsole portion form respective unitary structures, the second outsole portion having a substantially U-shape including a second medial leg and a second lateral leg, the first medial leg, the first lateral leg, the second medial leg, and the second lateral leg each extending toward an anterior end of the sole structure,

wherein the second outsole portion includes an interior leg extending in a direction away from the anterior end, and

wherein the interior leg extends between the first medial leg and the first lateral leg.

2. The sole structure of claim 1 , further comprising a third outsole portion spaced apart and separated from the first outsole portion and the second outsole portion.

3. The sole structure of claim 2 , wherein the third outsole portion includes a third medial leg and a third lateral leg each extending in a direction toward the anterior end of the sole structure.

4. The sole structure of claim 3 , wherein the third outsole portion includes an arcuate portion extending between and connecting the third medial leg and the third lateral leg.

5. The sole structure of claim 4 , wherein the third outsole portion includes an interior leg extending from the arcuate portion in a direction away from the anterior end.

6. The sole structure of claim 1 , wherein the first outsole portion comprises a first outsole material and the second outsole portion comprises a second outsole material, and the first outsole material and the second outsole material differ from each other in at least one of appearance, physical properties, and composition.

7. The sole structure of claim 1 , wherein the cushion comprises at least one of a fluid-filled chamber and a cushion material including one or more polymers.

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

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

a cushion including a series of lobes arranged from a forefoot region to a heel region along a medial side and a lateral side of the sole structure; and

an outsole having a first side attached to the cushion, a second side disposed on an opposite side of the outsole than the first side and defining a ground-contacting surface of the sole structure, a first outsole portion having a substantially U-shape and including a first medial leg and a first lateral leg, and a second outsole portion spaced apart and formed separately from the first outsole portion such that the first outsole portion and the second outsole portion form respective unitary structures, the second outsole portion having a substantially U-shape including a second medial leg and a second lateral leg, the first medial leg, the first lateral leg, the second medial leg, and the second lateral leg each including a longitudinal axis that extends substantially parallel to a longitudinal axis of the sole structure,

wherein the second outsole portion includes an interior leg extending in a direction away from an anterior end of the sole structure, and

wherein the interior leg extends between the first medial leg and the first lateral leg.

10. The sole structure of claim 9 , wherein the second outsole portion includes an arcuate portion extending between and connecting the second medial leg and the second lateral leg, the interior leg extending from the arcuate portion.

11. The sole structure of claim 9 , further comprising a third outsole portion spaced apart and separated from the first outsole portion and the second outsole portion.

12. The sole structure of claim 11 , wherein the third outsole portion includes a third medial leg and a third lateral leg each extending in a direction toward an anterior end of the sole structure.

13. The sole structure of claim 12 , wherein the third outsole portion includes an arcuate portion extending between and connecting the third medial leg and the third lateral leg.

14. The sole structure of claim 13 , wherein the third outsole portion includes an interior leg extending from the arcuate portion in a direction away from the anterior end.

15. The sole structure of claim 9 , wherein the cushion comprises at least one of a fluid-filled chamber and a cushion material including one or more polymers.

16. An article of footwear incorporating the sole structure of claim 9 .
