Abstract

A shoe includes an outsole including a ground contact surface to be in contact with the ground, and an upper attached directly or indirectly to the outsole opposite to the ground contact surface. The outsole includes an outsole body, and a roll-up portion extending from an edge of the outsole body toward the upper. The outsole also includes a flexible region in which at least one cut is formed to extend from the outsole body to the roll-up portion.

First claim

What is claimed is:

1. A shoe, comprising:
an outsole including a ground contact surface adapted to be in contact with the ground; and
an upper attached directly or indirectly to the outsole opposite to the ground contact surface, wherein
the outsole includes:
an outsole body;
a roll-up portion extending from an edge of the outsole body toward the upper;
a flexible region provided only on a lateral side of a forefoot portion of the outsole;
at least one cut extending from the outsole body to the roll-up portion and formed in the flexible region; and
a continuous portion that is coextensive with a medial half of a peripheral edge of the outsole body, wherein the continuous portion is continuous from a toe end of the outsole body to a heel end of the outsole body,

wherein, on a forefoot portion of the upper, an upper protection layer is provided,
wherein the upper protection layer includes a protection reinforcement part, and a flexibility providing part that is thinner than the protection reinforcement part,
wherein the shoe comprises an eyelet part through which a shoelace is inserted, wherein the protection reinforcement part is arranged near the eyelet part,
wherein the shoe comprises a slit formed on the upper to extend in a longitudinal direction of the upper, the eyelet part being formed on each of two opposing sides of the slit in a width direction of the slit, wherein, in a width direction of the shoe, the slit is formed closer to a side opposite to the flexible region with respect to a middle of the upper in the width direction of the shoe, and wherein, in the width direction of the shoe, the upper protection layer is provided closer to the flexible region than the slit, and the slit is further away from the flexible region than the upper protection layer.

2. The shoe according to claim 1 , wherein the at least one cut has a predetermined width in a longitudinal direction of the outsole.

3. The shoe according to claim 1 , comprising a midsole provided between the outsole and the upper, wherein the roll-up portion extends to a position higher than an upper surface of the midsole.

4. The shoe according to claim 1 , wherein the at least one cut extends continuously from the ground contact surface to the roll-up portion.

5. The shoe according to claim 4 , wherein the at least one cut extending to the ground contact surface is arranged at a position adapted to correspond to a metatarsal phalangeal joint of a wearer.

6. The shoe according to claim 4 , wherein the at least one cut comprises a plurality of cuts extending to the ground contact surface, wherein ends of the plurality of cuts positioned around a middle of the ground contact surface in a width direction of the ground contact surface of the outsole are arranged in a curved line.

7. The shoe according to claim 6 , wherein the curved line has a shape that bulges toward a lateral side of the ground contact surface in a width direction of the outsole.

8. The shoe according to claim 1 , wherein the at least one cut extends to an upper end of the roll-up portion.

9. The shoe according to claim 1 , wherein the at least one cut extends to around a middle of the ground contact surface in a width direction of the ground contact surface of the outsole.

10. The shoe according to claim 1 , wherein an intersection part between the ground contact surface and the roll-up portion of the outsole makes a substantially right angle.

11. The shoe according to claim 1 , wherein the upper protection layer is formed of rubber or resin.

12. The shoe according to claim 1 , wherein the flexibility providing part extends along an extended line of the at least one cut.

13. The shoe according to claim 1 , wherein the protection reinforcement part is arranged around an upper end of the roll-up portion.

14. The shoe according to claim 1 , comprising a shoe tongue having a length such that the shoe tongue can be folded back to reach a position forward of an uppermost eyelet part.
