The second portion 22b and the like.

The first portion 22a extends diagonally backward from the toe side string threading portion 28 and is alternately passed through the second string threading portion 26b and the third string threading portion 27a, and then the heel side string threading on the outer foot side. It is passed through the section 29. As shown in FIG. 2, in the state before the shoelace 22 is pulled, the second string threading portion 26b and the third string threading portion 27a are arranged so as to be displaced in the front-rear direction and the left-right direction. Therefore, the first portion 22a alternately passed through the second string threading portion 26b and the third string threading portion 27a extends in a zigzag shape in the left-right direction from the front to the rear.

The second portion 22b extends rearward from the toe side string threading portion 28 and is alternately passed through the first string threading portion 26a and the fourth string threading portion 27b, and then the heel side string threading portion on the inner foot side. It is passed through 29. As shown in FIG. 2, in the state before the shoelace 22 is pulled, the first string threading portion 26a and the fourth string threading portion 27b are arranged so as to be offset in the front-rear direction and the left-right direction. Therefore, the second portion 22b alternately passed through the first string threading portion 26a and the fourth string threading portion 27b extends in a zigzag shape in the left-right direction from the front to the rear. In the state before the shoelace 22 is pulled, the first portion 22a and the second portion 22b do not intersect each other. In the state before the shoelace 22 is pulled, a portion of the first portion 22a that is alternately passed through the second string threading portion 26b and the third string threading portion 27a, and a portion of the second portion 22b that is threaded through the first string. The portions alternately passed through the portion 26a and the fourth string threading portion 27b are parallel to each other.

By pulling the first portion 22a and the second portion 22b backward from the state shown in FIG. 2, the first side edge portion 20d and the second side edge portion 20e of the upper main body 20 are formed. Are attracted to each other. As a result, the distance between the second string threading portion 26b and the third string threading portion 27a in the left-right direction is shortened, and the distance between the first string threading portion 26a and the fourth string threading portion 27b in the left-right direction is shortened. Therefore, the first portion 22a alternately passed through the second string threading portion 26b and the third string threading portion 27a approaches a state of extending linearly in the front-rear direction, and the first string threading portion 26a and the fourth string are passed. The second portion 22b alternately passed through the passing portion 27b approaches a state of extending linearly in the front-rear direction. The first portion 22a and the second portion 22b do not intersect each other in a state where the shoelace 22 passed through the outer leg side string threading portion 26 and the inner leg side string threading portion 27 is pulled. In a state where the shoelace 22 passed through the outer leg side string threading portion 26 and the inner leg side string threading portion 27 is pulled, the second string threading portion 26b and the third string threading portion 27a of the first portion 22a The portion alternately passed through the second portion 22b and the portion alternately passed through the first string threading portion 26a and the fourth string threading portion 27b of the second portion 22b are parallel to each other.

Next, the effect of the upper 2 according to the present embodiment will be described.

In the present embodiment, as shown in FIG. 2, the upper 2 is separated from one first string threading portion 26a provided in the first forming portion 23 and the first string threading portion 26a on the outer leg side. The outer leg side string threading portion 26 is provided as a set with one second string threading portion 26b. Further, the upper 2 has one third string threading portion 27a provided in the second forming portion 24 and one fourth string threading portion 27b separated from the third string threading portion 27a on the inner leg side. A pair of inner leg side string threading portions 27 is provided. The first forming portion 23 and the second forming portion 24 are alternately provided in the front-rear direction, and the shoelace 22 is alternately passed through the second stringing portion 26b and the third stringing portion 27a. It has one portion 22a and a second portion 22b that is alternately passed through the first stringing portion 26a and the fourth stringing portion 27b. With these configurations, the first portion 22a and the second portion 22b do not intersect each other on the instep when the shoelace 22 is pulled as shown in FIG. Therefore, as compared with the case where the shoelaces 22 intersect on the instep, the pressure on the instep is reduced, and the feeling of tightening on the instep can be reduced.

In the present embodiment, as shown in FIG. 3, an outer leg side string threading portion 26 in which one first string threading portion 26a and one second string threading portion 26b are paired, and one third string. The inner leg side string threading portion 27, which is a set of the threading portion 27a and one fourth string threading portion 27b, is provided alternately in the front-rear direction. That is, since there are two string threading portions 25 alternately on the outer leg side and the inner leg side of the opening 20b, there is one string threading portion 25 alternately on the outer leg side and the inner leg side of the opening 20b. Compared to the case, when the shoelace 22 is pulled, the force of pulling the first side edge portion 20d and the second side edge portion 20e to each other is stronger. As a result, the upper 2 can be reliably brought into close contact with the foot.

In the present embodiment, as shown in FIG. 2, the first forming portion 23 in which the first stringing portion 26a is formed and the second forming portion 24 in which the third stringing portion 27a is formed alternate in the front-rear direction. In the configuration provided in, the first string threading portion 26a and the second string threading portion 26b are provided side by side in the left-right direction, and the third string threading portion 27a and the fourth string threading portion 27b are arranged side by side in the left-right direction. By being provided, the following three effects can be achieved. First, since the first portion 22a and the second portion 22b do not intersect each other on the instep, the effect of reducing the pressure on the instep can be achieved. The second reason is that there is no separation distance between the first string threading portion 26a and the second string threading portion 26b in the front-rear direction and the separation distance between the third string threading portion 27a and the fourth string threading portion 27b in the front-rear direction. It is possible to increase the number of pairs of the outer leg side string threading portion 26 and the inner leg side string threading portion 27, and it is possible to enhance the string tightening effect of the shoelace 22 on the upper body 20. Thirdly, even if the number of pairs of the outer leg side string threading portion 26 and the inner leg side string threading portion 27 is further increased as compared with the example shown in FIG. 2, the first portion 22a and the second portion 22b intersect with each other. The effect of not doing it can be achieved. That is, the first string threading portion 26a and the second string threading portion 26b are provided side by side in the left-right direction, and the third string threading portion 27a and the fourth string threading portion 27b are provided side by side in the left-right direction. As a result, while reducing the pressure on the instep, the effect of tightening the laces on the upper body 20 is enhanced, and even if the number of pairs of the laces 26 on the outer foot side and the laces 27 on the inner foot side is increased, the first It is possible to obtain a structure in which the portion 22a and the second portion 22b do not intersect each other.

In the present embodiment, as shown in FIG. 3, since the first forming portion 23 and the second forming portion 24 are integrally formed on the upper main body 20, the shoelace 22 does not need to add a new member. It is possible to realize a structure in which the two do not intersect.

In the present embodiment, as shown in FIG. 3, when the shoelace 22 is pulled, the first portion 22a and the second portion 22b do not intersect with each other, so that the first portion 22a is pulled when the shoelace 22 is pulled. Since there is no frictional resistance generated between the portion 22a and the second portion 22b, the shoelace 22 can be easily tightened.

In the present embodiment, as shown in FIG. 3, when the shoelace 22 is pulled, the first portion 22a and the second portion 22b approach a state in which they extend linearly in the front-rear direction without intersecting each other. .. As a result, the angle formed when the shoelaces 22 enter the laces 25 and exit the laces 25 becomes gentler than when the shoelaces 22 intersect. Therefore, the frictional resistance generated between the shoelace 22 and the stringing portion 25 when the shoelace 22 is pulled is reduced, so that the shoelace 22 can be easily tightened.

In the present embodiment, as shown in FIG. 3, when the shoelaces 22 are pulled, the first portion 22a and the second portion 22b do not intersect with each other, so that the shoelaces 22 do not intersect with each other, as compared with the case where the shoelaces 22 intersect. Since the pressure on the instep is reduced, the shoelace 21 shown in FIG. 1 can be thinned or eliminated.

In the present embodiment, as shown in FIG. 3, when the shoelaces 22 are pulled, the first portion 22a and the second portion 22b do not intersect with each other, so that the shoelaces 22 do not intersect with each other, as compared with the case where the shoelaces 22 intersect. , It becomes possible to shorten the length of the shoelace 22. Therefore, it is possible to reduce the weight of the shoe 1 and the environmental load.

In this embodiment, the case where the second stringing portion 26b is formed on the outer leg side of the first forming portion 23 is illustrated, but the second stringing portion 26b is formed on the first forming portion 23. You may. By doing so, the second string threading portion 26b and the third string threading portion 27a can be further brought closer to each other in the left-right direction. 3 The position of the string threading portion 27a can be aligned in the front-rear direction. As a result, the portion of the first portion 22a that is alternately passed through the second string threading portion 26b and the third string threading portion 27a is in a state of extending straight in the front-rear direction, and when the shoelace 22 is pulled, the shoe is shoeed. Since the frictional resistance generated between the lace 22 and the lace-through portion 25 is further reduced, it becomes easier to tighten the shoelace 22.

Further, in the present embodiment, the case where the fourth stringing portion 27b is formed on the inner foot side of the second forming portion 24 is illustrated, but the fourth stringing portion 27b is formed on the second forming portion 24. You may. By doing so, the first string threading portion 26a and the fourth string threading portion 27b can be further brought closer to each other in the left-right direction. Therefore, when the shoelace 22 is pulled, the position and the first string threading portion 26a 4 The position of the string threading portion 27b can be aligned in the front-rear direction. As a result, of the second portion 22b, the portions alternately passed through the first string threading portion 26a and the fourth string threading portion 27b are in a state of extending straight in the front-rear direction, and when the shoelace 22 is pulled, the shoe is shoeed. Since the frictional resistance generated between the lace 22 and the lace-through portion 25 is further reduced, it becomes easier to tighten the shoelace 22.
