Abstract

An upper including: a cord placed along the longitudinal direction, the cord running through the through holes of the reinforcement members of the medial side portion and/or the lateral side portion; exposed areas in which portions of the cord are placed exposed; and a shoelace engaging with the cord in the exposed areas in a transverse direction of the foot so as to bring the medial side portion and the lateral side portion closer to each other, wherein each of the upper end portions of at least one reinforcement member is attached to the flexible member in one of a fore portion and a rear portion, and is set to be un-attached to the flexible member in the other one of the fore portion and the rear portion.

First claim

The invention claimed is:

1. A shoe upper configured to cover at least a portion of a foot instep, the upper comprising:
a medial side portion configured to cover a medial side surface of the instep;
a lateral side portion configured to cover a lateral side surface of the instep;
at least one flexible member covering at least one of (i) a portion of the instep in the medial side portion and (ii) a portion of the instep in the lateral side portion;
at least one reinforcement member having a greater rigidity than the at least one flexible member, at least a lower half portion of at least one reinforcement member being attached to at least one of (i) a surface of at least one flexible member in the medial side portion, and (ii) a surface of at least one flexible member in the lateral side portion,
wherein the at least one reinforcement member includes a plurality of upper end portions spaced apart from one another in a longitudinal direction of the foot, and
wherein a through hole is defined in each upper end portion of the at least one reinforcement member and extends in a normal direction with respect to a surface of the at least one reinforcement member;
a cord provided along a central edge portion of at least one of (i) the medial side portion and (ii) the lateral side portion, the cord inserted through each through hole of at least one of (i) the medial side portion and (ii) the lateral side portion, the cord extending along the longitudinal direction, wherein portions of the cord include exposed areas; and
a shoelace engaging with the cord in the exposed areas in a transverse direction of the foot so as to relatively move the medial side portion and the lateral side portion closer to each other,
wherein each upper end portion of the at least one reinforcement member is attached to the flexible member in only one of (i) a fore portion and (ii) a rear portion, of each upper end portion.

2. The upper according to claim 1 , wherein the at least one reinforcement member is attached to the flexible member in only one of (i) the fore portion, (ii) the rear portion, and (iii) a top portion above the through hole.

3. The upper according to claim 1 , wherein one of the following (a) and (b) is set:
(a) each upper end portion of the at least one reinforcement member is attached to the flexible member in the fore portion, and is not attached to the flexible member in the rear portion,
(b) each upper end portion of the at least one reinforcement member is attached to the flexible member in the rear portion, and is not attached to the flexible member in the fore portion.

4. The upper according to claim 1 , wherein each upper end portion is not attached to the flexible member above the through hole.

5. The upper according to claim 1 , wherein, between two of the through holes that are adjacent to each other in the longitudinal direction, the cord extends (i) under a back side of one of the upper end portions and (ii) across a
front side of another one of the upper end portions, thereby forming, between the cord and the flexible member, a space, through which the shoelace passes.

6. The upper according to claim 1 , wherein:
between two through holes that are adjacent to each other in the longitudinal direction, the cord extends (i) under a back side of one of the upper end portions and (ii) across a front side of another one of the upper end portions,
whereby, of two upper end portions that are adjacent to each other, the back side of the one of the upper end portions and the front side of the other one of the upper end portions are disposed at least partially facing each other.

7. The upper according to claim 6 , wherein: the shoelace passes through a space formed between the cord and the flexible member.

8. The upper according to claim 1 , wherein a tensile rigidity of the cord is greater than a tensile rigidity of the shoelace.

9. The upper according to claim 1 , wherein two of the upper end portions that are adjacent to each other in the longitudinal direction partially overlap with each other as seen from a side view.

10. The upper according to claim 1 , wherein:
the at least one reinforcement member includes a strip portion extending from each upper end portion toward a shoe sole; and
an upper end of the strip portion includes a protruding portion which protrudes in at least one of (i) a forward direction and (ii) a rearward direction.

11. The upper according to claim 10 wherein: two upper end portions that are adjacent to each other in the longitudinal direction overlap with each other via the protruding portion as seen from a side view.

12. The upper according to claim 1 , wherein:
the at least one reinforcement member includes a plurality of strip portions each extending in at least one of (i) a downward direction and (ii) a diagonally downward direction; and
the upper further comprises a flexible portion where the flexible member is exposed between two of the strip portions that are adjacent to each other in the longitudinal direction.

13. The upper according to claim 1 , wherein:
each upper end portion is disposed in a forwardly-tilting orientation, extending in a diagonally rearward direction from each upper end portion toward a shoe sole; and
a posterior one of the upper end portions tilts more forward than an anterior one of the upper end portions.

14. The upper according to claim 1 , wherein:
the at least one reinforcement member includes a plurality of strip portions each extending from corresponding upper end portions in one of (i) a downward direction and (ii) a diagonally downward direction; and
at least two of the strip portions that are adjacent to each other in the longitudinal direction have lower end portions which are continuous with each other.

15. A shoe upper configured to cover at least a portion of a foot instep, the upper comprising:
a medial side portion configured to cover a medial side surface of the instep;
a lateral side portion configured to cover a lateral side surface of the instep;
at least one flexible member covering at least one of (i) a portion of the instep in the medial side portion and (ii) a portion of the instep in the lateral side portion;
at least one reinforcement member having a greater rigidity than the at least one flexible member, at least a lower half portion of at least one reinforcement member being attached to at least one of (i) a surface of at least one flexible member in the medial side portion, and (ii) a surface of at least one flexible member in the lateral side portion,
wherein the at least one reinforcement member includes a plurality of upper end portions spaced apart from one another in a longitudinal direction of the foot, and
wherein a through hole is defined in each upper end portion of the at least one reinforcement member and extends in a normal direction with respect to a surface of the at least one reinforcement member;
a cord provided along a central edge portion of at least one of (i) the medial side portion and (ii) the lateral side portion, the cord inserted through each through hole of at least one of (i) the medial side portion and (ii) the lateral side portion, the cord extending along the longitudinal direction, wherein portions of the cord include exposed areas; and
a shoelace engaging with the cord in the exposed areas in a transverse direction of the foot so as to relatively move the medial side portion and the lateral side portion closer to each other,
wherein each upper end portion of the at least one reinforcement member is attached to the flexible member in at least one of (i) a fore portion and
