Nowadays, a variety of footwear is produced and sold. Most shoes, especially sports shoes, are Shoelaces are used as elastic devices, although there are many other settings. For example, many casual shoes are equipped with elastic and elastic fabrics inside the shoe openings. Some are attached through Velcro, and some use buttons and fasteners. , although these are more convenient and faster than tying shoelaces, they will feel looser when you need to work, exercise or walk quickly, and you cannot tighten the shoes under your feet. Not only is it laborious, sometimes it may also be a safety hazard when exercising. In addition, after using it for a long time, The elastic fabric will gradually lose its elasticity, and the Velcro will not stick firmly.

In the existing technology, the traditional way of tying shoelaces by hand is the most stable and practical, but it also has many shortcomings. For example, when wearing shoes, you need to bend down or squat down, and use both hands to open or loosen the shoelaces to allow the feet to loosen. It is very inconvenient to enter, then tighten, knot and bind the shoelaces. If you feel it is too tight or too loose or the knot (bow) comes loose during the process, you have to reopen it, loosen it and then bind it tightly. It is not only troublesome but also harmful. It would be embarrassing, and it would be a huge safety risk if the shoelaces come off and are stepped on during exercise.

To sum up, it is necessary to invent a shoe that is both safe and firm, and can be easily and quickly adjusted in an automatic/semi-automatic manner. Such shoes should preferably be foot-controlled and do not require hands or bending during use. It can be operated by squatting or squatting, and preferably it can also maintain the appearance of traditional shoelaces.
