Abstract

A sole structure for an article of footwear includes a midsole having an upper surface and a ground-facing surface and a ground engaging sole component affixed to the ground-facing surface of the midsole. The ground engaging sole component includes a substrate layer, a support layer, and a plurality of cleats, each cleat coupled to the support layer and held apart from the midsole by a distance that is greater than 0.0 mm.

First claim

The invention claimed is:

1. A sole structure for an article of footwear having an upper adapted to receive a foot, the sole structure comprising:
a midsole having an upper surface and a ground-facing surface; and
a ground engaging sole component affixed to the ground-facing surface of the midsole, the ground engaging sole component comprising:
a substrate layer comprising a polymeric sheet, and wherein:
the substrate layer forms a plurality of recessed areas, where within each recessed area, the substrate layer contours away from the midsole to define a volume between the substrate layer and the midsole,
the substrate layer includes a bond surface that contacts and is secured to the midsole, and wherein the bond surface encircles each recessed area of the plurality of recessed areas;

a support layer joined with the substrate layer and operative to structurally reinforce the polymeric sheet; and
a plurality of cleats, each cleat coupled to the support layer within a recessed area, and wherein each cleat is spaced apart from the midsole by a distance that is greater than 0.0 mm.

2. The sole structure of claim 1 , wherein each cleat comprises a respective base portion and a ground engaging portion, the base portion at least partially extending between the support layer and the midsole.

3. The sole structure of claim 2 , wherein the ground engaging portion comprises a metal blade or post.

4. The sole structure of claim 2 , wherein the base portion of at least one of the plurality of cleats has an upper surface, opposite the ground engaging portion, that is concave relative to the midsole.

5. The sole structure of claim 1 , wherein the polymeric sheet has a thickness of less than about 1.0 mm.

6. The sole structure of claim 1 , wherein the support layer has a hardness that is greater than a hardness of the substrate layer.

7. The sole structure of claim 1 , wherein the plurality of cleats comprises 8 cleats.

8. The sole structure of claim 1 , wherein the sole structure further comprises a forefoot portion, a midfoot portion, and a heel portion; and
wherein at least three of the cleats are in the forefoot portion.

9. The sole structure of claim 1 , wherein the sole structure further comprises a forefoot portion, a midfoot portion, and a heel portion; and
wherein at least three of the cleats are in the heel portion.

10. The sole structure of claim 1 , wherein the support layer comprises a scaffold that includes a plurality of apertures defined between a plurality of adjoining scaffold segments.

11. The sole structure of claim 10 , wherein the substrate layer extends across each of the plurality of apertures.

12. The sole structure of claim 1 , wherein the support layer comprises a structure having a plurality of linear segments that are joined together to define a plurality of polygonal apertures; and
wherein the substrate layer extends across each of the plurality of apertures.

13. The sole structure of claim 12 , wherein the plurality of apertures comprises at least 100 apertures.

14. The sole structure of claim 12 , wherein the plurality of apertures comprises between 100 and 300 apertures and the plurality of cleats comprises between 3 and 15 cleats.

15. The sole structure of claim 1 , wherein the substrate layer and support layer are operative to flex within the recessed area such that the cleat within the recessed area contacts the midsole in response to an applied load.
