What is a "shoelace"?

Shoelace, also known as a shoe string, is a narrow strip of material that is laced through the eyelets or holes of shoes, sneakers, or other footwear to secure and tighten them around the foot. It is usually made of materials such as cotton, nylon, or leather and can come in various lengths, colors, and styles. The end of a shoelace is often finished with a plastic or metal aglet to make it easier to thread through the eyelets and prevent fraying.
