Abstract

An upper includes an inner skin placed on a wear'"'"'s skin side, and an outer skin placed on an opposite side from the inner skin, wherein a sponge member is housed between the inner skin and the outer skin in a heel portion; the sponge member includes a medial side portion covering a medial side of a calcaneal bone, and a lateral side portion covering a lateral side of the calcaneal bone; and in a developed view where the sponge member is unfolded into a planar shape, a height of a lateral first centroid of a portion corresponding to the lateral side portion is set to be higher than a height of a medial first centroid of a portion corresponding to the medial side portion.

Claims

1. A structure of an upper for improving a fitting property of a heel portion 10 of the upper 1 of a shoe, wherein:

the upper 1 includes an inner skin 11 placed on a wear'"'"'s skin side, and an outer skin placed on an opposite side from the inner skin 11, wherein a sponge member 3 is housed between the inner skin 11 and the outer skin in the heel portion 10;

the sponge member 3 includes a medial side portion 34 covering a medial side of a calcaneal bone Ca, and a lateral side portion 35 covering a lateral side of the calcaneal bone Ca; and

in a developed view where the sponge member 3 is unfolded into a planar shape, a level of a lateral first centroid O10 of a portion corresponding to the lateral side portion 35 is set to be higher than a level of a medial first centroid O11 of a portion corresponding to the medial side portion 34.

2. The structure according to claim 1, wherein the medial side portion 34 covers at least a portion of a lower edge Ce of the calcaneal bone Ca directly below a talus Ta, and the lateral side portion covers an area of the calcaneal bone Ca directly above a point O, wherein the point O bisects a distance between a lowermost end point Ae of a lateral ankle A0 and the lower edge Ce of the calcaneal bone Ca.

3. The structure according to claim 2, wherein the sponge member 3 includes a thin portion 3a having a small thickness, and a thick portion 3b thicker than the thin portion 3a, and wherein with the sponge member 3 unfolded, a perimeter of the thick portion 3b is surrounded by the thin portion 3a.

4. The structure according to claim 3, wherein in a developed view where the thick portion 3b is unfolded into a planar shape, a level of a lateral second centroid O20 of a portion of the thick portion 3b corresponding to the lateral side portion is set to be higher than a level of a medial second centroid O21 of a portion of the thick portion 3b corresponding to the medial side portion 34.

5. The structure according to claim 3, wherein a lower edge line 3bL of the thick portion 3b extends, while being upwardly slanted, from a medial side of the heel portion 10 to a lateral side of the heel portion 10 via a back side of the heel portion 10.

6. The structure according to claim 2, wherein a lower edge line 3L of the sponge member 3 extends, while being upwardly slanted, from a medial side of the heel portion 10 to a lateral side of the heel portion 10 via a back side of the heel portion 10.

7. The structure according to claim 3, wherein the sponge member 3 comprises:

a first sponge plate 31 extending along a medial side of a heel coming from a back side of the heel and also extending along a lateral side of the heel coming from the back side of the heel; and

a second sponge plate 32 laid on a foot skin side of the first sponge plate 31, the second sponge plate 32 having a smaller area than the first sponge plate 31, wherein;

the second sponge plate 32 is laid on a portion of the first sponge plate 31 while being bonded, glued or welded to the first sponge plate 31;

the thin portion 3a is formed by a portion of the first sponge plate 31 on which the second sponge plate 32 is unlaid; and

the thick portion 3b is formed by a portion where the second sponge plate 32 is laid on the first sponge plate 31.

8. The structure according to claim 7, wherein the second sponge plate 32 is formed by a material having a lower resilience than the first sponge plate 31.

9. The structure according to claim 7, wherein the second sponge plate 32 is formed by a material having a lower hardness than the first sponge plate 31.

10. The structure according to claim 7, wherein the second sponge plate 32 is formed by a material having a lower resilience and a lower hardness than the first sponge plate 31.

11. The structure according to claim 2, wherein the sponge member 3 further comprises a back portion 30 covering a calcaneal tuberosity Cp from directly behind along a virtual line CL dividing the sponge member 3 into the medial side portion 34 and the lateral side portion 35, and the sponge member 3 defines a narrowed portion 36 that is narrowed downwardly along the virtual line CL without covering an area above the calcaneal tuberosity Cp.

12. A structure for improving a fitting property of a heel portion 10 of an upper 1 of a shoe, wherein:

the upper 1 includes an inner skin 11 placed on a wear'"'"'s skin side, and an outer skin on an opposite side from the inner skin 11, wherein a sponge member 3 is housed between the inner skin 11 and the outer skin in the heel portion 10;

the sponge member 3 includes a medial side portion 34 covering a medial side of a calcaneal bone Ca, and a lateral side portion 35 covering a lateral side of the calcaneal bone Ca;

the medial side portion 34 covers at least a portion of a lower edge Ce of the calcaneal bone Ca directly below a talus Ta, and the lateral side portion 35 covers an area of the calcaneal bone Ca directly above a point O, wherein the point O bisects a distance between a lower end of a lateral ankle A0 and the lower edge Ce of the calcaneal bone Ca;

the sponge member 3 includes a first sponge plate 31 extending along a medial side of a heel coming from a back side of the heel and also extending along a lateral side of the heel coming from the back side of the heel, and a second sponge plate 32 laid on a foot skin side of the first sponge plate 31, the second sponge plate 32 having a smaller area than the first sponge plate 31; and

the second sponge plate 32 is partially laid on the first sponge plate 31 while being bonded, glued or welded together to the first sponge plate 31.

13. The structure according to claim 12, wherein the sponge member 3 further comprises a back portion 30 covering a calcaneal tuberosity Cp from directly behind along a virtual line CL dividing the sponge member 3 into the medial side portion 34 and the lateral side portion 35, and the sponge member 3 defines a narrowed portion 36 that is narrowed downwardly along the virtual line CL without covering an area above the calcaneal tuberosity Cp.

14. The structure according to claim 12, wherein the second sponge plate 32 is formed by a material having a lower resilience and/or a lower hardness than the first sponge plate 31.
