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, polyester, or leather and come in various lengths, colors, and styles. Laces are threaded through eyelets, which are small holes reinforced with metal or fabric, allowing for a snug fit around the foot. In addition to footwear, laces can also be found in other applications, such as clothing and sports equipment. They serve both functional and decorative purposes, enhancing the overall appearance of items while providing necessary support and security.
