Abstract

An article of footwear may include an upper and a sole structure fixedly attached to a bottom portion of the upper. The sole structure may include a sole component including a baseplate having a bottom surface and at least a first ground engaging member extending substantially downward from the bottom surface of the baseplate, the first ground engaging member having a substantially circular cross-sectional shape. In addition, the sole structure may also include a tapered support structure having a substantially pyramidal shape and extending substantially downward from the bottom surface of the baseplate, abutting the first ground engaging member at a side portion, and partially surrounding the first ground engaging member such that a portion of the first ground engaging member is exposed between edges of the tapered support structure. Also, the tapered support structure may extend downward from the baseplate less than the first ground engaging member.

Claims

1. An article of footwear, including an upper configured to receive a foot and a sole structure fixedly attached to a bottom portion of the upper, the sole structure including a ground engaging sole component comprising:

a baseplate having a bottom surface;

at least a first ground engaging member extending substantially downward from the bottom surface of the baseplate, the ground engaging member having a stepped cross-sectional size with an upper portion of the ground engaging member having a larger cross-sectional size than a lower portion of the ground engaging member, the transition between the upper portion and the lower portion forming a step; and

a first elongate support member extending substantially downward from the bottom surface of the baseplate, abutting the first ground engaging member at a side portion, and extending horizontally from the side portion of the first ground engaging member independent of other ground engaging members, wherein the first support member projects downward from the baseplate and extends below the step in the cross-section of the ground engaging member.

2. The article of footwear according to claim 1, wherein the sole component includes multiple elongate support members extending substantially downward from the bottom surface of the baseplate, abutting the first ground engaging member at a side portion, and extending radially from the first ground engaging member.

3. The article of footwear of claim 2, wherein the elongate support members are substantially evenly spaced about the first ground engaging member.

4. The article of footwear according to claim 1, wherein the first ground engaging member has a height, and wherein the first support member extends downward from the bottom surface of the baseplate less than the full height of the first ground engaging member.

5. The article of footwear according to claim 1, wherein the step includes a rounded transition between the step and at least one of the upper portion and the lower portion of the first ground engaging member.

6. The article of footwear according to claim 1, wherein the first ground engaging member has a substantially circular cross-sectional shape.

7. The article of footwear according to claim 1, wherein the first ground engaging member has a substantially frustoconical shape.

8. An article of footwear, including an upper configured to receive a foot and a sole component fixedly attached to a bottom portion of the upper, the sole component comprising:

a baseplate having a bottom surface and including a substantially square platform having a lower surface;

at least a first ground engaging member extending downward from the lower surface of the substantially square platform, the first ground engaging member having a substantially circular cross-sectional shape; and

a first elongate support member abutting the first ground engaging member at a side portion, and extending downward from the baseplate and horizontally from the side portion of the first ground engaging member, the first elongate support member attaching to the lower surface of the substantially square platform proximate a first corner of the substantially square platform.

9. The article of footwear of claim 8, further including a second elongate support member, a third elongate support member, and a fourth elongate support member, abutting the first ground engaging member at side portions of the elongate support member, and extending downward from the baseplate and horizontally from the side portion of the first ground engaging member;

wherein the second elongate support member, the third elongate support member, and the fourth elongate support member respectively attach to the lower surface of the substantially square platform in a second corner, a third corner, and a fourth corner of the substantially square platform.

10. The article of footwear of claim 8, wherein the first elongate support member extends to an edge of the substantially square platform at the corner of the substantially square platform.

11. The article of footwear of claim 8, wherein the first ground engaging member has a height, and wherein the first elongate support member extends downward from the bottom surface of the baseplate less than the full height of the first ground engaging member.

12. The article of footwear of claim 11, wherein the first elongate support member extends downward more than half the height of the first ground engaging member.

13. The article of footwear according to claim 8, wherein the first ground engaging member has a substantially frustoconical shape.

14. An article of footwear, including an upper configured to receive a foot and a sole structure fixedly attached to a bottom portion of the upper, the sole structure including a sole component comprising:

a baseplate having a bottom surface, a peripheral edge, a longitudinal axis, and a lateral axis;

an arrangement of ground engaging members extending downward from the bottom surface of the baseplate proximate the peripheral edge of the baseplate, each of the ground engaging members being located on an axis passing through the respective ground engaging member and oriented substantially perpendicular to the peripheral edge of the baseplate proximate the respective ground engaging member;

a plurality of elongate support members extending downward from the bottom surface of the baseplate and abutting side portions of the ground engaging members;

wherein the arrangement of ground engaging members includes at least three ground engaging members,

wherein the plurality of elongate support members includes at least three sets of four evenly spaced support members, the elongate support members of each set abutting one of the at least three ground engaging members;

wherein each support member of the at least three sets of elongate support members is oriented in substantial non-alignment with the axis of the abutting ground engaging member; and

wherein each support member of the at least three sets of elongate support members is oriented in a substantially non-parallel orientation with respect to the longitudinal axis of the baseplate.

15. The article of footwear of claim 14, wherein each support member of the at least three sets of elongate support members is oriented at substantially the same angle with respect to the axis of the abutting ground engaging member.

16. The article of footwear of claim 14, wherein all of the ground engaging members in the arrangement are abutted by four evenly spaced elongate support members oriented in substantial non-alignment with the axis of the abutting ground engaging member and in a substantially non-parallel orientation with respect to the longitudinal axis of the baseplate.

17. The article of footwear of claim 14, wherein at least one of the ground engaging members is abutted by one or more elongate support members oriented in substantial alignment with the longitudinal axis.

18. The article of footwear of claim 14, wherein one or more of the ground engaging members in the arrangement has a substantially circular cross-sectional shape.

19. The article of footwear of claim 18, wherein the first ground engaging member has a substantially frustoconical shape.

20. The article of footwear of claim 14, wherein the baseplate includes a gap at the peripheral edge of the baseplate, and wherein at least one of the plurality of elongate support members extends horizontal away from one of the ground engaging embers towards a protruding portion of the baseplate adjacent to the gap.
