Abstract

A shoe with belts according to the present invention comprising an upper, a sole S that has a first and second roll-up portions S11, S10 rolling upwards along side faces of a foot, and first and second belts 51, 52. The first belt 51 is fixed to the first roll-up portion S11 at a first joined portion 58 on the medial side of the foot. The second belt 52 is fixed to the second roll-up portion S10 at a second joined portion 59 on the lateral side of the foot. The pair of belts 51, 52 cross each other at a position approximately above the navicular bone 91. The first belt 51 can be arranged in a tensioned state along a path extending from the medial side of the foot to the vicinity of an ankle on the lateral side of the foot through the crossing position 57. The second belt 52 can be arranged in a tensioned state along a path extending from the lateral side to the vicinity of the ankle on the medial side of the foot through the crossing position 57.

Claims

1. A shoe comprising:

an upper;

a sole that is joined to the upper and has a first roll-up portion rolling upwards along a medial side face of a foot and a second roll-up portion rolling upwards along a lateral side face of the foot;

a first belt fixed to the first roll-up portion of the sole at a first joined portion below a navicular bone and/or a medial cuneiform bone on the medial side of the foot; and

a second belt fixed to the second roll-up portion of the sole at a second joined portion covering a distal caput of a fifth metatarsal bone on the lateral side of the foot,

the first belt has the first joined portion, a first secured portion to be secured to the upper, and a first non-fixed portion that is not fixed to the upper or the sole between the first joined portion and the first secured portion,

the second belt has the second joined portion, a second secured portion to be secured to the upper, and a second non-fixed portion that is not fixed to the upper or the sole between the second joined portion and the second secured portion,

the first non-fixed portion of the first belt and the second non-fixed portion of the second belt cross each other in the shape of X at a crossing position approximately above the navicular bone,

by having the first non-fixed portion, the first belt can be arranged in a tensioned state along a path extending from below the navicular bone and/or the medial cuneiform bone on the medial side of the foot to above or below an ankle on the lateral side of the foot through the crossing position approximately above the navicular bone without being restrained by the upper, and

by having the second non-fixed portion, the second belt can be arranged in a tensioned state along a path extending from the position covering the distal caput of the fifth metatarsal bone to above or below the ankle on the medial side of the foot through the crossing position approximately above the navicular bone without being restrained by the upper.

2. A shoe according to claim 1, wherein

the first roll-up portion has a first face joined to the upper and the first joined portion of the first belt overlaps the first face, and

the second roll-up portion has a second face joined to the upper and the second joined portion of the second belt overlaps the second face.

3. A shoe according to claim 1, wherein

the first belt and the second belt are made of material which is essentially difficult to stretch.

4. A shoe according to claim 1, wherein each of the first and second belts is narrower in width at the crossing position than at their respective joined portion.

5. A shoe according to claim 1, wherein the upper comprises an inner upper covering an instep of the foot and an outer upper covering the inner upper and the pair of belts.

6. A shoe according to claim 5, wherein

a first slit is provided in the inner upper in the vicinity of the ankle on the lateral side of the foot,

a second slit is provided in the inner upper in the vicinity of the ankle on the medial side of the foot,

the first belt has a first double part formed doubly in a loop shape in a path extending from the crossing position to above or below the ankle on the lateral side of the foot,

the second belt has a second double part formed doubly in a loop shape in a path extending from the crossing position to above or below the ankle on the medial side of the foot,

a belt portion on the reverse side of the first double part passes through the first slit, and

a belt portion on the reverse side of the second double part passes through the second slit

7. A shoe according to claim 5, wherein a first secured portion of the first belt is detachably secured to the inner upper in the vicinity of the ankle on the lateral side of the foot, and a second secured portion of the second belt is detachably secured to the inner upper in the vicinity of the ankle on the medial side of the foot.

8. A shoe according to claim 7, further comprising a covering part for covering the two secured portions.

9. A shoe according to claim 8, wherein the covering part is composed of a third belt and a fourth belt that are secured to the inner upper around the ankle so as to bind the ankle.

10. A shoe according to claim 8, wherein the inner upper further comprises a folding portion folded downward and the folding portion constitutes the covering part.

11. A shoe comprising

an upper;

a sole joined to the upper;

a first belt fixed to the sole at a first joined portion below a navicular bone and/or a medial cuneiform bone on a medial side of the foot, and

a second belt fixed to the sole at a second joined portion covering a distal caput of a fifth metatarsal bone on a lateral side of the foot, wherein

a first slit is formed in the upper in the vicinity of an ankle on the lateral side of the foot,

a second slit is formed in the upper in the vicinity of the ankle on the medial side of the foot,

the pair of belts cross each other in the shape of X at a crossing position approximately above the navicular bone,

the first belt passes through the first slit in the vicinity of the ankle on the lateral side of the foot for tensioning the first belt along a path extending from below the navicular bone and/or the medial cuneiform bone on the medial side of the foot to the vicinity of the ankle on the lateral side of the foot through the crossing position approximately above the navicular bone, and

the second belt passes through the second slit in the vicinity of the ankle on the medial side of the foot for tensioning the second belt along a path extending from a position covering the distal caput of the fifth metatarsal bone to the vicinity of the ankle on the medial side of the foot through the crossing position approximately above the navicular bone.
