Abstract

A sole includes a base having a medial side and a lateral side; and a plurality of projections extending from the base, wherein at least one of the projections includes a first pod filled with ambient air and a foam layer disposed below the first pod. The first pod and the foam layer are disposed such that the projection extends non-orthogonally from the base.

First claim

What is claimed is:

1. A sole for an article of footwear, comprising:
a base forming a bottom surface of the sole and having a medial side and a lateral side; and
a plurality of projections extending from the base, wherein at least one of the projections includes a first pod filled with ambient air and having a bottom surface, a second pod filled with ambient air and having a top surface, and an exterior foam layer disposed on an exterior surface of the first pod below the first pod and farther from the base than the first pod and above the second pod, wherein a top surface of the exterior foam layer is foam and wherein foam extends from the bottom surface of the first pod to the top surface of the second pod,
wherein the first pod and the exterior foam layer are disposed such that the projection extends non-orthogonally from the base, and
wherein a shape of a horizontal cross-section of the exterior foam layer is the same as a shape of a horizontal cross-section of the first pod.

2. The sole of claim 1 , wherein the second pod is fluidly connected to the first pod.

3. The sole of claim 1 , further comprising an indent formed in the base, and wherein the first pod is disposed in the indent.

4. The sole of claim 1 , wherein the projection is a lateral projection on the lateral side of the sole and further comprising a medial projection on the medial side of the sole also including an air filled pod, wherein the lateral projection is fluidly connected to the medial projection.

5. The sole of claim 1 , wherein the exterior foam layer is not in contact with the base.

6. An article of footwear comprising:
a sole comprising a main sole body and a plurality of projections extending from the main sole body, the sole having a medial side, a lateral side, and a longitudinal axis,
wherein at least one of the projections includes a projection assembly,
wherein the projection assembly includes a first pod, a second pod, and a third pod, wherein the first pod and second pod are fluid bladders configured to retain a fluid therein, and wherein the first and second pods are fluidly connected, and
wherein the projection assembly is disposed below the main sole body and is vertically arranged in layers.

7. The article of footwear of claim 6 , wherein the third pod is disposed between the first and second pods.

8. The article of footwear of claim 7 , wherein the third pod is a foam pod.

9. The article of footwear of claim 6 , wherein the first and second pods are fluidly connected by a corrugated passageway.

10. The article of footwear of claim 6 , wherein outsole material is provided on the second pod.

11. The article of footwear of claim 6 , wherein at least one projection extends at an angle from the main sole body.

12. The article of footwear of claim 6 , wherein the projection assembly is a lateral projection assembly on the lateral side of the sole and further comprising a medial projection assembly on the medial side of the sole, wherein the lateral projection assembly and the medial projection assembly are positioned at substantially the same position along the longitudinal axis of the sole, and wherein the lateral projection assembly is fluidly connected to the medial projection assembly.

13. The article of footwear of claim 12 , further comprising a bridge connecting the second pod of the lateral projection assembly to the second pod of the medial projection assembly.

14. The article of footwear of claim 6 , further comprising a rear heel projection extending at an angle from the rear of the main sole body.

15. The article of footwear of claim 6 , wherein at least one of the projections includes a single fluid bladder.

16. The article of footwear of claim 15 , wherein two projections include a single fluid bladder, and wherein the two projections including a single fluid bladder are fluidly connected.

17. A sole for an article of footwear, comprising:
a base forming a bottom surface of the sole and having a medial side and a lateral side; and
a plurality of projections extending from the base, wherein at least one of the projections includes a first fluid-filled pod having a bottom surface, a second fluid-filled pod having a top surface, and a foam layer disposed between the first fluid-filled pod and the second fluid-filled pod, wherein a top surface of the foam layer is foam and wherein foam extends from the bottom surface of the first fluid-filled pod to the top surface of the second fluid-filled pod;
wherein the second fluid-filled pod is not in direct contact with the base, and
wherein the at least one projection extends non-orthogonally from the base.

18. The sole of claim 17 , where the at least one projection is a lateral projection on the lateral side of the sole and further comprising a medial projection on the medial side of the sole, the medial projection including:
a third fluid-filled pod;
a fourth fluid-filled pod; and
a foam layer disposed between the third fluid-filled pod and the fourth fluid-filled pod;
wherein the lateral projection is fluidly connected to the medial projection.

19. The sole of claim 18 , wherein the first fluid-filled pod is fluidly connected to the third fluid-filled pod.
