Abstract

A sole for a shoe, the sole comprising reinforcing members extending in a front half of the sole, wherein at least a first one of the reinforcing members further extends rearwardly beyond a midfoot area and into a heel area of the sole and wraps up to a posterior portion of an ankle region. A shoe, in particular a running shoe, comprising such a sole. A method for the manufacture of such items.

First claim

What is claimed is:

1. A sole for a shoe, the sole comprising:
a plurality of reinforcing members comprising at least three reinforcing members, wherein:
each one of the plurality of reinforcing member comprises a portion extending in a front half of the sole,
a first one of the reinforcing member extends rearwardly and forms a first section of the reinforcing members behind a midfoot area of the sole,
a second one of the reinforcing members extends rearwardly and forms a second section of the reinforcing members behind the midfoot area of the sole, and
the first section and the second section merge into each other in a heel area to form a loop shape and are configured to be disposed below and support a heel of a wearer,

wherein the plurality of reinforcing members converge in a connection region, and wherein a rearward end of the connection region is disposed forward of the loop shape.

2. The sole according to claim 1 , wherein at least two of the plurality of reinforcing members are directly coupled to each other in the connection region.

3. The sole according to claim 1 , wherein the connection region comprises a connection member integrally formed with at least two of the plurality of reinforcing members.

4. The sole according to claim 1 , wherein the first one of the reinforcing members and the second one of the reinforcing member diverge as they extend from the connection region towards the heel area.

5. The sole according to claim 1 , wherein the connection region is disposed in the midfoot area of the sole.

6. The sole according to claim 1 , wherein the plurality of reinforcing members are at least partially embedded in a midsole of the sole.

7. The sole according to claim 1 , wherein the first section and the second section comprise a first stiffness, and the portion of each reinforcing member in the front half of the sole comprises a second stiffness lower than the first stiffness.

8. The sole according to claim 1 , wherein the portion of each reinforcing member in the front half of the sole is configured to be independently deflected by forces acting on the sole during a gait cycle.

9. The sole according to claim 1 , wherein the first one of the reinforcing members is an outermost medial reinforcing member, and the second one of the plurality of reinforcing members is outermost lateral reinforcing member of the plurality of reinforcing members.

10. A shoe comprising the sole according to claim 1 .

11. A sole for a shoe, the sole comprising:
a connection member;
a first plurality of reinforcing members extending forwardly away from the connection member in a front half of the sole and comprising at least three reinforcing members; and
a second plurality of reinforcing members extending rearwardly away from the connection member in a heel area of the sole, wherein:
a first one of the second plurality of reinforcing members extends rearwardly and forms a first section of the first one of the second plurality of reinforcing members behind a midfoot area of the sole,
a second one of the second plurality of reinforcing members extends rearwardly and forms a second section of the second one of the second plurality of reinforcing members behind the midfoot area of the sole, and
the first section and the second section merge into each other in a heel area and are configured to be disposed below and support a heel of a wearer.

12. The sole according to claim 11 , wherein the connection member is integrally formed with at least one of the first plurality of reinforcing members and at least one of the second plurality of reinforcing members.

13. The sole according to claim 11 , further comprising a connection region, wherein the first plurality of reinforcing members converge in the connection region.

14. The sole according to claim 13 , wherein a first one of the first plurality of reinforcing members merges with the first one of the second plurality of reinforcing members in the connection region.

15. The sole according to claim 14 , wherein a second one of the first plurality of reinforcing members merges with the second one of the second plurality of reinforcing members in the connection region.

16. The sole according to claim 14 , wherein the second one of the second plurality of reinforcing members couples to the connection member in the connection region, and
wherein the connection member is integrally formed with the first one of the first plurality of reinforcing members and the first one of the second plurality of reinforcing members.

17. The sole according to claim 11 , wherein a first one of the first plurality of reinforcing members merges with at least one of the second plurality of reinforcing members.

18. The sole according to claim 17 , wherein a second one of the first plurality of reinforcing members merges with at least one of the second plurality of reinforcing members.
