5. The upper according to claim 4, wherein a center line of the third reinforcement portion along a direction in which the third reinforcement portion extends in a diagonally rearward and downward direction toward the sole.

6. The upper according to claim 4, wherein the angle formed between the center line of the fourth reinforcement portion and the horizontal line is smaller than an angle formed between a center line of the third reinforcement portion along a direction in which the third reinforcement portion extends and the horizontal line.

7. The upper according to claim 2, wherein:

a line along a rear end of the fourth reinforcement portion is more tilting forward than a line along a rear end of the second reinforcement portion; and

a lower end of the line along the rear end of the fourth reinforcement portion is placed posterior to a lower end of the line along the rear end of the second reinforcement portion, with the fourth reinforcement portion configured to cover a front portion of a lower portion of a calcaneal bone from a side surface.

8. The upper according to claim 2, wherein an area of a medial-side soft region, in which the member forming the sock is exposed, between the third reinforcement portion and the fourth reinforcement portion on the medial side surface is larger than an area of a lateral-side soft region, in which the member forming the sock is exposed, between the first reinforcement portion and the second reinforcement portion on the lateral-side surface.

9. The upper according to claim 2 wherein the third reinforcement portion has a width, and a width of a lower end portion of the third reinforcement portion is smaller than a width of an upper end portion of the third reinforcement portion.

10. The upper according to claim 2 wherein the second reinforcement portion has a width, and a width of a lower end portion of the second reinforcement portion is smaller than a width of an upper end portion of the second reinforcement portion.

11. The upper according to claim 2 wherein the first reinforcement portion has a width, and a width of a lower end portion of the first reinforcement portion is smaller than a width of an upper end portion of the first reinforcement portion.

12. The upper according to claim 2, wherein:

the width of the third reinforcement portion is smaller at a lower end portion thereof than at an upper end portion thereof;

the width of the second reinforcement portion is smaller at a lower end portion thereof than at an upper end portion thereof; and

the width of the first reinforcement portion is smaller at a lower end portion thereof than at an upper end portion thereof.
