Abstract

An article of footwear is provided and includes an upper having a bottom surface and a first plate attached to the bottom surface of the upper in a forefoot region. The first plate includes a lateral peripheral cleat disposed adjacent to a first outward-most portion of the upper on a lateral side and a medial peripheral cleat disposed adjacent to a second outward-most portion of the upper on a medial side, the medial peripheral cleat being disposed closer to an anterior end of the first plate than the lateral peripheral cleat.

First claim

The invention claimed is:

1. An article of footwear comprising:
an upper having a bottom surface;
a first plate attached to the bottom surface of the upper in a forefoot region and including a lateral peripheral cleat disposed adjacent to a first outward-most portion of the upper on a lateral side and a medial peripheral cleat disposed adjacent to a second outward-most portion of the upper on a medial side, the medial peripheral cleat being disposed closer to an anterior end of the first plate than the lateral peripheral cleat, each of the peripheral cleats including a stud, including an inner surface, having a substantially triangular cross-sectional shape and a first blade, having an inner surface, extending along a first longitudinal direction from a first end attached to an anterior end of the stud toward a terminal end disposed between the stud and the anterior end, and a second blade, having an inner surface, extending along a second longitudinal direction from a first end attached to a posterior end of the stud toward a terminal end disposed between the stud and the posterior end, wherein outer surfaces of the stud, the first blade, and the second blade form a substantially continuous outer surface of the plate, and wherein an intersection between the inner surface of the stud and the inner surface of the first blade has a first radius of curvature, and an intersection between the inner surface of the stud and the inner surface of the second blade has a second radius of curvature different from the first radius of curvature; and
a first serrated region disposed between the lateral peripheral cleat and the medial peripheral cleat and including a plurality of elongate first ribs extending from a bottom surface of the first plate, wherein each of the first ribs includes a central portion, a first end, and a second end opposite the first end, a height of each of the first ribs tapering from a tallest height at the central portion to shorter heights at the first end and at the second end.

2. The article of footwear of claim 1 , wherein the first outward-most portion of the upper and the second outward-most portion of the upper are aligned along a metatarsophalangeal axis.

3. The article of footwear of claim 1 , wherein each stud of the peripheral cleats is disposed at the respective outward-most portion of the upper, and wherein the stud includes an outward-facing surface disposed adjacent to a peripheral surface of the first plate.

4. The article of footwear of claim 1 , wherein first ribs of the plurality of elongate first ribs include an arcuate shape.

5. The article of footwear of claim 1 , wherein first ribs of the plurality of elongate first ribs include a concave surface formed on a first side of each first rib and a convex surface formed on an opposite side of each first rib.

6. The article of footwear of claim 5 , wherein the concave surface of each first rib faces the anterior end of the first plate.

7. The article of footwear of claim 5 , wherein the concave surface of each first rib faces a posterior end of the first plate.

8. The article of footwear of claim 1 , further comprising:
a second serrated region disposed between the lateral peripheral cleat and the medial peripheral cleat and including a plurality of elongate second ribs extending from the bottom surface of the first plate, wherein at least one first rib of the plurality of elongate first ribs includes a first concave surface and at least one second rib of the plurality of elongate second ribs includes a second concave surface, the first concave surface facing the anterior end of the first plate and the second concave surface facing a posterior end of the first plate.

9. An article of footwear comprising:
an upper having a bottom surface;
a first plate attached to the bottom surface of the upper in a forefoot region and including a first peripheral cleat disposed adjacent to a peripheral side surface of the first plate on a lateral side and a second peripheral cleat disposed adjacent to a peripheral side surface on a medial side, each of the first peripheral cleat and the second peripheral cleat (i) including a central stud having a substantially triangular cross-sectional shape and at least one blade having a first end attached to an anterior end of the stud and a terminal end disposed between the central stud and a terminal end of the article of footwear, wherein the at least one blade has a height that tapers downward from the first end to the terminal end, the at least one blade extending in a longitudinal direction along the peripheral side surface of the first plate and (ii) being offset from one another along a longitudinal axis of the first plate; and
a first serrated region disposed between the first peripheral cleat and the second peripheral cleat and including a plurality of elongate first ribs extending from a bottom surface of the first plate, wherein each of the first ribs includes a central portion, a first end, and a second end opposite the first end, a height of each of the first ribs tapering from a tallest height at the central portion to shorter heights at the first end and at the second end.

10. The article of footwear of claim 9 , wherein the central stud and the at least one blade of the first peripheral cleat cooperate to form a first continuous outer surface adjacent to the peripheral side surface on the lateral side, and the central stud and the at least one blade of the second peripheral cleat cooperate to form a second continuous outer surface adjacent to the peripheral side surface on the medial side.

11. The article of footwear of claim 9 , wherein the at least one blade includes a first blade extending along a first longitudinal direction from an anterior end of the central stud, and a second blade extending along a second longitudinal direction from a posterior end of the central stud, and wherein the central stud includes an outward-facing surface disposed adjacent to a peripheral surface of the first plate.

12. The article of footwear of claim 9 , wherein the first ribs of the plurality of elongate first ribs include an arcuate shape.

13. The article of footwear of claim 9 , wherein the first ribs of the plurality of elongate first ribs include a concave surface formed on a first side of each first rib and a convex surface formed on an opposite side of each first rib.

14. The article of footwear of claim 13 , wherein the concave surface of each first rib faces an anterior end of the first plate.

15. The article of footwear of claim 13 , wherein the concave surface of each first rib faces a posterior end of the first plate.

16. The article of footwear of claim 9 , further comprising:
a second serrated region disposed between the first peripheral cleat and the second peripheral cleat and including a plurality of elongate second ribs extending from the bottom surface of the first plate, and wherein at least one first rib of the plurality of elongate first ribs includes a first surface that is concave when viewed from an anterior end of the first plate and at least one second rib of the plurality of elongate second ribs includes a second surface that is convex when viewed from the anterior end of the first plate.

17. The article of footwear of claim 1 , wherein (i) the first blade and the second blade of each of the peripheral cleats includes a height that tapers downward from the first end to the terminal end, the first blade and the second blade extending in a longitudinal direction along the peripheral side surface of the first plate such that the first blade, the second blade,
