Abstract

A multi-colored effect for a sole structure for an article of footwear is disclosed. The sole structure comprises a sole member having a first color and an exterior layer having a second color that is different from the sole member. A plurality of slots are formed in the sole structure and the second color is visible on an outer surface of the sole structure through the plurality of slots.

Claims

1. An article of footwear, comprising:

a sole structure including a side portion, a lower portion and a lower periphery disposed between the side portion and the lower portion;

the side portion extending from the lower periphery to an upper periphery of the sole structure, thereby forming a vertical sidewall of the sole structure;

a first slot disposed in the side portion and a second slot disposed in the lower portion, wherein the first slot extends from an outer surface of the side portion to a central portion of the sole structure;

wherein the first slot has a first depth and a second depth, wherein the second depth is disposed further from the upper periphery than the first depth and wherein the second depth is greater than the first depth;

a first connecting portion extending from the central portion of the sole structure to the lower periphery, the first connecting portion separating the first slot from the second slot;

a second connecting portion extending to an upper periphery of the sole structure and wherein the first connecting portion is joined to the second connecting portion at the central portion of the sole structure;

wherein the first connecting portion and the second connecting portion are visible through the first slot;

the outer surface of the side portion having a first color and the connecting portion having a second color that is different from the first color; and

wherein a portion of the connecting portion is visible through the first slot.

2. The article of footwear according to claim 1, wherein a deepest portion of the first slot is proximate the central portion and wherein a deepest portion of the second slot is proximate the central portion.

3. The article of footwear according to claim 1, wherein the first slot is generally oriented vertically, so that a longest dimension of the first slot is oriented in a direction perpendicular to both a longitudinal direction and a lateral direction of the sole structure.

4. The article of footwear according to claim 3, wherein the second slot includes a longest dimension that extends in a lateral direction on the lower portion.

5. The article of footwear according to claim 1, wherein the first slot has a wedge-like shape.

6. The article of footwear according to claim 1, wherein the outer surface is associated with a portion of an upper that is disposed on the side portion of the sole structure.

7. The article of footwear according to claim 1, wherein the outer surface is associated with a matrix portion of a tread assembly.

8. An article of footwear, comprising:

a sole structure comprising a lateral side portion, a medial side portion and a lower portion;

the medial side portion extending from a medial lower periphery of the sole structure to a medial upper periphery of the sole structure, thereby forming a medial vertical sidewall of the sole structure;

the lateral side portion extending from a lateral lower periphery of the sole structure to a lateral upper periphery of the sole structure, thereby forming a lateral vertical sidewall of the sole structure;

the sole structure further comprising a first portion and a second portion, the first portion and the second portion having an approximately rectangular cross-sectional shape;

a hollowed out portion disposed between the first portion and the second portion, the hollowed out portion comprising a first slot disposed on the lateral side portion, a second slot disposed on the medial side portion and a third slot disposed on the lower portion;

wherein the first slot includes a first end portion adjacent to the lateral upper periphery of the sole structure and a second end portion adjacent to the lateral lower periphery of the sole structure;

wherein the first slot is generally oriented vertically, so that a longest dimension of the first slot is oriented in a direction perpendicular to both a longitudinal direction and a lateral direction of the sole structure;

the hollowed out portion further comprising a connecting member that extends between the first portion and the second portion;

wherein the connecting member comprises a first connecting portion extending to the lateral upper periphery of the sole structure and a second connecting portion extending to the lateral lower periphery of the sole structure and wherein the first connecting portion is joined to the second connecting portion at a central portion of the connecting member;

the connecting member having a first color and the lateral side portion, the medial side portion and the lower portion having a second color that is different from the first color; and

wherein the first color is visible through the first slot, the second slot and the third slot.

9. The article of footwear according to claim 8, wherein a longest dimension of the third slot is oriented in the lateral direction.

10. The article of footwear according to claim 8, wherein the connecting member is comprised of three or more connecting portions.

11. The article of footwear according to claim 8, wherein the first connecting portion and the second connecting portion are visible through the first slot.

12. The article of footwear according to claim 11, wherein the connecting member comprises a third connecting portion extending to the medial lower periphery of the sole structure and a fourth connecting portion extending to the medial upper periphery of the sole structure and wherein the third connecting portion is joined to the fourth connecting portion at the central portion and wherein the third connecting portion and the fourth connecting portion are visible through the second slot and wherein the second connecting portion and the third connecting portion are visible through the third slot.

13. The article of footwear according to claim 12, wherein the connecting member has an X-like cross sectional shape.

14. The article of footwear according to claim 8, wherein the first slot has a first depth and a second depth, wherein the second depth is disposed further from the upper periphery than the first depth and wherein the second depth is substantially different than the first depth.

15. The article of footwear according to claim 14, wherein the second depth is substantially greater than the first depth.

16. An article of footwear, comprising:

a sole structure including a lateral side portion, a lower portion and a lateral lower periphery disposed between the lateral side portion and the lower portion;

the sole structure comprising a midsole having a first color;

an insert disposed within a cavity of the midsole, the insert having a second color that is different from the first color;

a first slot disposed on the lateral side portion of the sole structure, the first slot extending through the midsole and a portion of the insert;

a second slot disposed on the lower portion of the sole structure, the second slot extending through the midsole and a portion of the insert;

a first connecting portion of the sole structure extending from a central portion of the sole structure to the lateral upper periphery of the sole structure;

a second connecting portion of the sole structure extending from the central portion of the sole structure to the lateral lower periphery and separating the first slot from the second slot;

a third connecting portion extending to a medial lower periphery of the sole structure;

a fourth connecting portion extending to a medial upper periphery of the sole structure;

wherein the third connecting portion is joined to the fourth connecting portion at the central portion and wherein the third connecting portion and the fourth connecting portion are visible through a third slot and wherein the second connecting portion and the third connecting portion are visible through the second slot;

wherein the first slot is bounded from above by the first connecting portion and wherein the first slot is bounded from below by the second connecting portion; and

wherein a portion of the insert is visible through the first slot.

17. The article of footwear according to claim 16, wherein a portion of the midsole is visible through the second slot.

18. The article of footwear according to claim 16, wherein the insert is an airbag.

19. The article of footwear according to claim 16, wherein the insert is a foam insert.

20. The article of footwear according to claim 16, wherein the first slot is approximately aligned with the second slot with respect to a longitudinal direction that extends along a length of the sole structure.
