Abstract

An article of footwear, comprising: an upper having an outer surface, a foot insertion volume and a sole facing surface, a sole assembly comprising: a midsole having a foot facing surface, a ground facing surface, a heel region, forefoot region and an arch region between the heel region and the forefoot region in a longitudinal direction, where the midsole in the arch region comprises a medial support element covering at least a part of the cuboid bone of the foot and/or a lateral support element covering at least a part of the navicular bone, a medial reinforcement member positioned medial to the medial support element and/or a lateral reinforcement member positioned lateral to the lateral support element, where the medial and/or the lateral reinforcement member is configured to increase the rigidity of the medial support element and/or the lateral support element.

First claim

The invention claimed is:

1. An article of footwear comprising:
an upper having an outer surface, a foot insertion volume, and a sole facing surface, a sole assembly comprising:
a midsole having a foot facing surface, a ground facing surface, a heel region, a forefoot region, and an arch region between the heel region and the forefoot region in a longitudinal direction, where the midsole in the arch region comprises a medial support element configured to cover at least a part of the cuboid bone of the foot or a lateral support element configured to cover at least a part of the navicular bone, and
a medial reinforcement member positioned medial to the medial support element or a lateral reinforcement member positioned lateral to the lateral support element, where the medial reinforcement member or the lateral reinforcement member is configured to increase rigidity of the medial support element or the lateral support element,

wherein the medial reinforcement member and/or the lateral reinforcement member extends in the longitudinal direction towards the forefoot region from a position in the longitudinal direction, which position is less than 40% of a length of the longitudinal length of the sole assembly from a heel end of the sole assembly, and
wherein the upper is configured to connect a part of a medial side of the sole assembly to a part of a lateral side of the sole assembly by a part of the upper positioned above the foot insertion volume.

2. The article of footwear according to claim 1 , wherein the medial reinforcement member or the lateral reinforcement member has a first distal end, the heel end and a toe end, where one or more of the first distal end, the heel end, and the toe end abuts the upper.

3. The article of footwear according to claim 1 , wherein the medial support element or the lateral support element has a first material hardness and the medial reinforcement member or the lateral reinforcement member has a second material hardness, where the first material hardness is different than the second material hardness.

4. The article of footwear according to claim 3 , where the first material hardness is lower than the second material hardness.

5. The article of footwear according to claim 1 , wherein the medial support element or the lateral support element has a first height, where the first height is higher than the height of the midsole in a central region in a lateral direction.

6. The article of footwear according to claim 1 , wherein the midsole in the heel region comprises a heel support element configured to cover at least part of a tuberosity of the calcaneus of the foot of the wearer.

7. The article of footwear according to claim 1 , wherein the medial support element or the lateral support element have an upper vertical end, where the upper vertical end is positioned in a region that is between 0-50% of a distance from the upper facing part of the midsole and an instep part of the upper.

8. The article of footwear according to claim 1 , wherein the part of the upper positioned above the foot insertion volume and configured to connect the part of the medial side of the sole assembly to the part of the lateral side of the sole assembly includes a lace for connecting opposing parts of the upper.

9. The article of footwear according to claim 1 , wherein a material of the midsole is PU, or the material of the medial reinforcement member and the lateral reinforcement member is TPU.

10. The article of footwear according to claim 1 , wherein the medial support element or the lateral support element extends from the foot facing surface in a vertical direction.

11. The article of footwear according to claim 1 , wherein the medial support element or the lateral support element extends from the foot facing surface in a medial direction.

12. The article of footwear according to claim 1 , wherein the medial support element or the lateral support element abuts the outer surface of the upper.

13. The article of footwear according to claim 1 , wherein the medial reinforcement member or the lateral reinforcement member enclose at least part of a lateral surface of the medial support element or the lateral support element, respectively, wherein the medial reinforcement member or the lateral reinforcement member is configured to enclose an entirety of the lateral surface of the medial support element or the lateral support element, respectively.

14. The article of footwear according to claim 1 , wherein the medial support element or the lateral support element extends from the ground facing surface of the midsole in a vertical direction.

15. The article of footwear according to claim 1 , wherein a part of the medial support element or the lateral support element has a height in a vertical direction that is at least 150% of the height of the midsole in a central area defined in a lateral direction.

16. An article of footwear, comprising:
an upper having an outer surface, a foot insertion volume, and a sole facing surface,
a sole assembly comprising:
a midsole having a foot facing surface, a ground facing surface, a heel region, a forefoot region, and an arch region between the heel region and the forefoot region in a longitudinal direction, where the midsole in the arch region comprises a medial support element configured to cover at least a part of the cuboid bone of the foot and a lateral support element configured to cover at least a part of the navicular bone, and
a medial reinforcement member positioned medial to the medial support element and a lateral reinforcement member positioned lateral to the lateral support element, where either the medial reinforcement member is configured to increase the rigidity of the medial support element, the lateral reinforcement member is configured to increase the rigidity of the lateral support element, or both the medial reinforcement member is configured to increase the rigidity of the medial support element and the lateral reinforcement member is configured to increase rigidity of the lateral support element,

wherein the medial reinforcement member and/or the lateral reinforcement member extends in the longitudinal direction towards the forefoot region from a position in the longitudinal direction, which position is less than 40% of a length of the longitudinal length of the sole assembly from the heel end of the sole assembly, and
wherein the upper is configured to connect a part of a medial side of the sole assembly to a part of a lateral side of the sole assembly by a part of the upper positioned above the foot insertion volume.

17. The article of footwear according to claim 16 , wherein a part of one or more of the medial support element and the lateral support element has a height in a vertical direction that is at least 150% of the height of the midsole in a central area defined in a lateral direction.

18. The article of footwear according to claim 16 , wherein the medial support element and the lateral support element have a first material hardness and the medial reinforcement member and the lateral reinforcement member have a second material hardness, where the first material hardness is different than the second material hardness.

19. The article of footwear according to claim 16 , wherein the medial support element and the lateral support element have an upper vertical end, where the upper vertical end is positioned in a region that is between 0-50% of a distance from the upper facing part of the midsole and an instep part of the upper.
