Abstract

An asymmetric pair of shoes to optimize performance during a sporting activity, the asymmetric pair of shoes, including: a first shoe having a first upper and a first sole attached to the first upper, wherein the first upper comprises a first support feature configured to provide increased support to at least one portion of the first upper during performance of a first predetermined action of a first foot of a wearer, and the first sole comprises a first traction feature configured to provide increased traction to at least one portion of the first sole during performance of the first predetermined action of the first foot; and a second shoe having a second upper and a second sole attached to the second upper, wherein the first support feature and first traction feature are not present at corresponding mirror-image locations of the second shoe.

First claim

What is claimed is:

1. An asymmetric pair of shoes, comprising: a first shoe having a first upper and a first sole attached to the first upper, wherein the first upper comprises a first support feature configured to provide increased support to at least one portion of the first upper during performance of a first predetermined action of a first foot of a wearer, and the first sole comprises a first traction feature configured to provide increased traction to at least one portion of the first sole during performance of the first predetermined action of the first foot; and a second shoe having a second upper and a second sole attached to the second upper, wherein the first support feature and first traction feature are not present at corresponding mirror-image locations of the second shoe, wherein the first support feature comprises a first enhanced support zone located at a lateral middle to forefoot area of the first upper, and the first enhanced support zone provides greater support and flexibility to a lateral middle to forefoot area of the first upper compared to other areas of the first upper, wherein the first sole comprises a first outsole, a first midsole and first midsole reinforcement structure, and the second sole comprises a second outsole, a second midsole and second midsole reinforcement structure, the first midsole reinforcement structure is attached to the first midsole between the first midsole and the first upper and surrounds an upper portion of the first midsole along a heel portion of the first midsole with increasing coverage until the first midsole reinforcement structure covers substantially an entire side surface area of the first midsole in a forefoot area of the first midsole, and wherein the design and shape of the first midsole reinforcement structure is different on a medial side compared to a lateral side, and the second midsole reinforcement structure is attached to the second midsole between the second midsole and the second upper and surrounds an upper portion of the second midsole along a heel portion of the second midsole with increasing coverage until the second midsole reinforcement structure covers substantially an entire side surface area of the second midsole in a forefoot area of the second midsole.

2. The asymmetric pair of shoes of claim 1 , wherein the first enhanced support zone comprises an energy sling covering a lateral forefoot area of the first upper, wherein the energy sling is made from at least one material that provides increased support to the lateral forefoot area compared to other areas of the first upper while enhancing at least one of a stretch and a rebound characteristic of the lateral forefoot area.

3. The asymmetric pair of shoes of claim 2 , wherein the at least one material comprises at least one of rubber and thermoplastic polyurethane.

4. The asymmetric pair of shoes of claim 2 , wherein the first enhanced support zone further comprises a first saddle covering a lateral middle area of the first upper, wherein the first saddle is made from at least one material that provides increased strength to the lateral middle area of the first upper to provide increased support to the lateral middle area of the first upper.

5. The asymmetric pair of shoes of claim 1 , wherein the first upper further comprises a closure that is offset closer to a medial side of the first upper so as to increase a surface area of the first enhanced support zone.

6. The asymmetric pair of shoes of claim 1 , wherein the first traction feature comprises a longitudinal groove on a bottom surface of the first sole that spans substantially the length of the first sole.

7. The asymmetric pair of shoes of claim 6 , wherein the longitudinal groove spans at least 75% of the length of the first sole.

8. The asymmetric pair of shoes of claim 6 , wherein the longitudinal groove comprises at least one cut-out portion that further facilitates bending along the longitudinal groove.

9. The asymmetric pair of shoes of claim 1 , wherein the first support feature comprises a first heel counter located on a heel area of the first upper, wherein a medial portion of the first heel counter located on a medial side of the heel area of the first upper is larger than a lateral portion of the first heel counter located on a lateral side of the heel area of the first upper.

10. The asymmetric pair of shoes of claim 1 , wherein the second upper comprises a second support feature configured to provide increased support to at least one portion of the second upper during performance of a second predetermine action of a second foot of the wearer, and the second sole comprises a second traction feature configured to provide increased traction to at least one portion of the second sole during performance of the second predetermined action, wherein the first predetermined action of the first foot is different from the second predetermined action of the second foot, and the second support feature and the second traction feature are not present at corresponding mirror-image locations of the first shoe.

11. The asymmetric pair of shoes of claim 10 , wherein the second support feature comprises a second enhanced support zone located at a lateral middle to heel location of the second upper, wherein the second enhanced support zone is stronger and more flexible than other areas of the second upper.

12. The asymmetric pair of shoes of claim 11 , wherein the second enhanced support zone comprises a second heel counter located at a heel area of the second upper, wherein a lateral portion of the second heel counter located on a lateral side of the heel area of the second upper is larger than a medial portion of the second heel counter located on a medial side of the heel area of the second upper.

13. The asymmetric pair of shoes of claim 11 , wherein the second enhanced support zone further comprises a second saddle covering a lateral middle area of the second upper, wherein the second saddle is made from at least one material that provides increased strength to the lateral middle area of the second upper while enhancing at least one of a stretch and a rebound characteristic of the lateral middle area of the second upper.

14. The asymmetric pair of shoes of claim 10 , wherein the second traction feature comprises ball and big toe traction zones configured to generally correspond to a ball and a big toe location of the second foot, each of the ball and big toe traction zones containing a single large traction element larger than traction elements in other traction zones on the second sole.

15. The asymmetric pair of shoes of claim 10 , wherein the first traction feature comprises a first configuration of a first plurality of traction zones, the second traction feature comprises a second configuration of a second plurality of traction zones, each of the first and second pluralities of traction zones having at least one traction element extending outwardly from a surface thereof, wherein the first configuration of the first plurality of traction zones is different from a mirror image of the second configuration of the second plurality of traction zones.

16. The asymmetric pair of shoes of claim 15 , wherein a flexible lining material is fixedly coupled to each of the first and second plurality of traction zones and the at least one traction element extending outwardly from each of the first and second plurality of traction zones is fixedly coupled to the flexible lining material of each of the first and second plurality of traction zones.

17. The asymmetric pair of shoes of claim 1 , wherein a first configuration of th
