When the shoelace 120 connected to the handle 130 is pulled out laterally along the handle 130, the shoelaces 120 of the upper and lower sides of the shoelace 120 are connected to the handle 130. The opening 111 is tightened while being pulled out.

Subsequently, the shoelaces 120 pulled using the handle 130 are fixed to the fixed hooks 140 formed on both rear sides of the shoe body 110, respectively. At this time, since the fixing hook 140 is formed a plurality of spaced apart a predetermined interval, it is possible to fix to the appropriate fixing hook 140 according to the length of the shoelace 120 is pulled (see Fig. 2).

FIG. 5 is a front view illustrating a state in which the shoelace 120 of the lower region is tightened by pulling the tow line 154 of the tightening means 150, and when the tow line 154 exposed to the upper end side of the tongue 112 is pulled, the side wall The second connection member 154a connected to the shoelace 120 intersected via the through hole 152 at both ends of the lower end of 151 moves upward with the tow line 154 to the second connection member 154a. Since the connected shoelace 120 is pulled, both sides of the opening 111 corresponding to the lower end of the side wall 151 are tightened.

At this time, since the cross section of the shoelace 120 in the X-shape is pulled by the tow line 154, the shoelace 120 is about four times the length of the length to which the tow line 154 is pulled Is pulled.

On the other hand, in the process of tightening the opening 111 by pulling the shoelace 120 at the lower end of the side wall 151 by pulling the tow line 154 as described above, the second connection connected to the bottom of the tow line 154 When the member 154a interferes with the first connection member 153 installed on the shoelace 120 intersecting at the upper end of the side wall 151, the shoelace 120 is also pulled at the upper end of the side wall 151.

FIG. 6 is a front view showing a state in which the pull line 154 of the tightening means 150 is further tightened to tighten the shoelace 120 in the upper region, and the pull line 154 in the process of pulling the pull line 154 as described above. The second connecting member 154a connected to the lower end of the c) interferes with the first connecting member 153.

Since the string 120 is pulled upward, both sides of the opening 111 corresponding to the upper end of the side wall 151 are tightened.

That is, by pulling the one traction line 154, the shoelace 120 of the lower end and the upper end of the side wall 151 is tightened at the same time.

Here, since the upper region is wider than the lower region when the opening 111 is opened, and the tightening length in the upper region is formed longer than the tightening length in the lower region when the shoe is worn, the first connection member 153 The position where the second connection member 154a interferes is preferably set to a position spaced apart by a tightening distance of the upper region from a sufficiently tightened lower region of the opening 111. (In this embodiment, the second connecting member 154a connected to the lower end of the tow line 154 has been described as interfering with the first connecting member 153 to move the first connecting member 153, but the shoelace 120 It may be possible to additionally install a separate fixing member that interferes with the first connecting member 153 on the traction line 154 to adjust the tightening distance of.)

In particular, the upper region of the opening 111 tightened by pulling the handle 130 does not have a large margin in the tightening length of the shoelace 120, while the lower region has a margin in the tightening length of the shoelace 120. Therefore, as described above, by pulling the traction cord 154 to sufficiently tighten the shoelace 120 of the lower region of the opening 111, and then tighten the entire region of the opening 111 by tightening the shoelace 120 of the upper region. It can be tightened with relatively even pressure.

In addition, since the shoelace 120 is tightened by about four times the length to which the user pulls the tow line 154, the exposure length of the tow line 154 is shortened to facilitate the post-treatment, as well as one tow line By pulling 154, the upper and lower shoelaces 120 are tightened at the same time, thus providing an easy-to-use advantage.
