Laces are thin, flexible cords or strings used to secure shoes, boots, and other types of footwear. They are typically made from materials like cotton, nylon, or leather and come in various lengths and colors. Laces are threaded through eyelets, which are small holes reinforced with metal or fabric, allowing for a snug fit. In addition to footwear, laces can also be found in other items like clothing and bags. They serve both functional and decorative purposes, enhancing the overall appearance of the item while providing a means to adjust tightness or fit.
