Abstract

During a sporting activity, a player can be tackled or a body collision can occur. However, due to the ground penetration of the ground engaging members, the wearer’s shoe often remains engaged with the ground during the initial impact, rather than moving in response to the impact. As a result, during the initial impact the wearer’s heel remains unmoved with respect to the toes, while his or her leg turns or moves sideways from the force of the impact. The twisting or turning which potentially results at the ankle of the player can lead to injuries. The present invention relates to a shoe sole having different traction provided by the front and rear arrays of the ground engaging formations to assist to minimise the likelihood of injuries of this kind. The shoe sole comprising a bottom surface having a front region and a heel region with a central longitudinal axis extending in a direction from the heel region to the front region; a plurality of front ground penetrating formations arranged in the front region configured to engage with and penetrate the ground during a sporting activity, the plurality of front ground penetrating formations in the front region comprising a plurality of studs projecting from the bottom surface; and a plurality of rear ground penetrating formations arranged in the heel region configured to engage with and penetrate the ground during a sporting activity, the plurality of rear ground penetrating formations in the heel region comprising elongated ribs projecting from the bottom surface, wherein the elongated ribs are the only rear ground penetrating formations extending from the bottom surface, and wherein each elongated rib has a direction of elongation which is non-parallel to the longitudinal axis and/or each elongated rib extends laterally with respect to the longitudinal axis, wherein the studs in the front region have a first height or depth from the bottom surface and the elongated ribs in the heel region have a second height or depth from the bottom surface which is less than the first height or depth.

Claims

1. A shoe sole for a sport shoe, the shoe sole sing: a bottom surface having a front region and a heel region with a central longitudinal axis extending in a direction from the heel region to the front region; a plurality of front ground penetrating formations arranged in the front region ured to engage with and penetrate the ground during a sporting activity, the plurality of front ground penetrating formations in the front region comprising a ity of studs projecting from the bottom surface; and a plurality of rear ground penetrating formations arranged in the heel region configured to engage with and ate the ground during a sporting activity, the plurality of rear ground penetrating formations in the heel region comprising elongated ribs projecting from the bottom surface, wherein the elongated ribs are the only rear ground penetrating formations extending from the bottom surface, and wherein each elongated rib has a direction of elongation which is non-parallel to the longitudinal axis and/or each elongated rib extends laterally with respect to the udinal axis, wherein the studs in the front region have a first height or depth from the bottom surface and the ted ribs in the heel region have a second height or depth from the bottom surface which is less than the first height or depth.

2. A shoe sole as claimed in claim 1, wherein the elongated ribs are V shaped having two legs g at an apex, the V shaped ribs extending from one side of the sole to the other, and being spaced apart from one another in the direction of the longitudinal axis with each leg extending laterally with respect to the longitudinal axis.

3. A shoe sole as claimed in claim 2, wherein the elongated ribs are arranged in spaced apart relation, one behind the other, the apex of each elongated rib extending forwardly with respect to the legs, s the front region, the apexes aligned along the longitudinal axis.

4. A shoe sole as claimed in claim 1, wherein the elongated ribs are arranged in spaced apart parallel relation one behind the other and extend from one side of the sole to the other at about right angles to the longitudinal axis.

5. A shoe sole as claimed in claim 1, wherein the elongated ribs are boomerang shaped or crescent shaped and are arranged in spaced apart relation one behind the other.

6. A shoe sole as claimed in claim 1, wherein there is a first group of said elongated ribs having their elongation direction in a first orientation which is lateral with t to the longitudinal axis and a second group of said elongated ribs having their tion direction in a second orientation which is lateral with respect to the longitudinal axis.

7. A shoe sole as claimed in claim 1, wherein the studs have a base and a crown or tip spaced from the base, the base having a base diameter and the crown or tip having a crown diameter, the base diameter being greater than the crown diameter.

8. A shoe sole as claimed in claim 1, n the studs are in the shape of a truncated cone.

9. A shoe sole as claimed in claim 1, wherein the elongated ribs in the heel region are oriented to facilitate lateral movement of the heel region when engaged with and penetrating the ground.

10. A shoe comprising a shoe sole as claimed in any one of claims 1 to 9.
