Abstract

An athletic shoe including: an interior member; and a loop-shaped wrap, wherein the wrap includes: a heel portion covering a part of a calcaneal bone; a band-shaped and/or cord-shaped twisted portion continuous with a front end portion of the heel portion on medial side, extending toward under a foot sole while twisted on medial side; a medial bottom portion continuous with a front end portion of the twisted portion, extending along a medial side portion to a ball of a big toe under the foot sole; and a band-shaped and/or cord-shaped diagonal transverse portion continuous with a front end portion of the heel portion on lateral side, covering a portion of a cuboid bone and/or a tuberosity of a fifth metatarsal bone, and further extending across an instep diagonally forward so as to cover an upper surface of the big toe and a side surface of the ball.

Claims

1. An athletic shoe comprising:

an interior member adapted to be in contact with a surface of a foot; and

a loop-shaped wrap covering a portion of the interior member and formed by a material less stretchable than the interior member, wherein the wrap includes;

a heel portion adapted to continuously cover a medial side, a back surface and a lateral side b of a calcaneal bone;

a twisted portion having a band-shaped and/or cord-shaped configuration continuous with a front end portion of the heel portion on the medial side of the heel portion, the twisted portion adapted to extend toward under a foot sole while being twisted on the medial side of the foot;

a medial bottom portion continuous with a front end portion of the twisted portion, the medial bottom portion adapted to extend along a medial side portion of the foot sole to a ball of a big toe under the foot sole; and

a diagonal transverse portion having a band-shaped and/or cord-shaped configuration continuous with a front end portion of the heel portion on the lateral side of the heel portion, the diagonal transverse portion adapted to cover at least a portion of a cuboid bone and/or at least a portion of a tuberosity of a fifth metatarsal bone, and adapted to further extend across an upper surface of an instep in a diagonally forward direction so as to cover a portion of an upper surface of the big toe and at least a portion of a side surface of the ball of the big toe.

2. The athletic shoe according to claim 1, wherein:

the diagonal transverse portion includes a first portion and a second portion each having a band-shaped and/or cord-shaped configuration; and

the athletic shoe further comprises a connecting structure J for detachably connecting together the first portion and the second portion.

3. The athletic shoe according to claim 2, wherein the connecting structure is such that:

a tip portion of the second portion defines a through hole, through which the first portion is passed, and a tip portion of the first portion is inserted through the through hole and is folded back.

4. The athletic shoe according to claim 3, further comprising a shoelace for fastening an upper adapted to wrap around the instep, wherein:

the shoelace is engaged with the folded-back tip portion of the first portion.

5. The athletic shoe according to claim 1, further comprising an exterior member covering at least a portion of the interior member, wherein:

a portion of the diagonal transverse portion is arranged between the interior member and the exterior member.

6. The athletic shoe according to claim 5, wherein:

the interior member includes a lateral-side interior member adapted to be in contact with a lateral side surface of the foot;

the exterior member includes a lateral-side exterior member covering the lateral-side interior member; and

a portion of the diagonal transverse portion is arranged between the lateral-side interior member and the lateral-side exterior member.

7. The athletic shoe according to claim 6, wherein:

in at least a portion of an area of the lateral-side exterior member that is covering the diagonal transverse portion and at least a portion of an area of the lateral-side exterior member that is anterior to the diagonal transverse portion, the lateral-side exterior member is unattached to the lateral-side interior member; and

a plurality of engagement portions, with which a shoelace for fastening an upper adapted to wrap around the instep, are provided in a non-attached portion of the lateral-side exterior member that is unattached to the lateral-side interior member.

8. The athletic shoe according to claim 7, wherein:

between adjacent ones of the engagement portions, the lateral-side exterior member has a cutout extending downward from an upper end of the lateral-side exterior member.

9. The athletic shoe according to claim 6, further comprising:

an attached portion where the lateral-side exterior member is integrally attached to the lateral-side interior member in the heel portion; and

a non-attached portion where the lateral-side exterior member is adapted to be unattached to the lateral-side interior member at least in an upper portion of a middle foot section,

wherein an area from a front end to a rear end of an upper portion of the non-attached portion is set to be unattached to the lateral-side interior member.

10. The athletic shoe according to claim 1, further comprising:

an outsole having a tread surface;

a midsole of which a primary component is a foam body of a thermoplastic resin arranged on the outsole; and

an upper secured to the midsole and adapted to wrap around the instep, wherein the twisted portion and the diagonal transverse portion are formed by a band-shaped and/or cord-shaped member that is less stretchable than the midsole.

11. The athletic shoe according to claim 1, further comprising:

a sole having a plurality of cleats of which a primary component is a leather or a non-foam body of a synthetic resin; and

an upper secured to the sole and adapted to wrap around the instep,

wherein the medial bottom portion is formed by at least a portion of the sole.

12. The athletic shoe according to claim 1, wherein:

an upper adapted to wrap around the instep includes the interior member and an exterior member that is less stretchable than the interior member;

a lower edge of the exterior member extends along an inner surface of an upper edge of a sole; and

the lower edge of the exterior member and a portion of the sole form at least a portion of the medial bottom portion.

13. The athletic shoe according to claim 12, wherein the sole includes:

an outsole having a tread surface;

a midsole of which a primary component is a foam body of a thermoplastic resin arranged on the outsole; and

a reinforcement member configured to be attached to the midsole along an arch at least on the medial side of the foot for preventing the arch of the foot from lowering,

wherein the midsole is reinforced by the reinforcement member, thereby reinforcing the medial bottom portion.

14. The athletic shoe according to claim 1, wherein:

one end portion of the diagonal transverse portion is configured to extend from a side surface of the ball of the big toe so as to slip under the ball of the big toe, and is configured to extend along an upper surface of a sole so as to cover at least a portion of a bottom surface of the ball of the big toe.

15. The athletic shoe according to claim 1, wherein:

a sole comprises a roll-up portion configured to be rolled up on a medial side of a middle foot section; and

the front end portion of the twisted portion is configured to extend along an upper surface of the roll-up portion so as to slip into between an arch on the medial side of the foot sole and the roll-up portion.

16. The athletic shoe according to claim 1, wherein:

the diagonal transverse portion is configured to extend spirally and continuously along a surface of the instep along a path to a portion of the upper surface of the big toe starting from an area adapted to cover at least a portion of the cuboid bone and/or at least a portion of the tuberosity of the fifth metatarsal bone.
