Curly No Tie Shoe lace is made of elastic material and has a spiral design that can be held in place without tying. The Curly No Tie lace is ideal for elder or people with disabilities who have been injured by surgery. They may not be able to wear shoes and tie laces. The bright colors and ease of use are also suitable for children. Elastic materials stretch as your feet move to provide comfort without pinching your feet while still providing enough tension to prevent the shoes from falling out. The size is suitable for all standard shoes but not for boots.
