There is a problem that can be given.

In addition, the prior art is the second, because the shoelace insertion hole of the shoelace tightening device of the flat type is disposed on the front side, the shoelace is received and fixed inside the shoelace due to the tension applied to the shoelace when worn. The rear of the tightening device is not only not good for aesthetics as it stands vertically on the instep of the shoe, and it is uncomfortable because the shoelace tightening device and the shoelace out of the drawer become jammed due to the standing protrusion, and it is painful by applying pressure to a specific part of the instep. There was a problem that caused it.

In addition, the prior art third, if the shoelace is fastened to the shoe and the remaining shoelace is long, the shoelace must be accommodated inside the shoelace tightening device, and the shoelace exited through the withdrawal hole must be tied again or inserted into the space between the shoelaces. There was a problem that the end treatment was inconvenient.
