Shoelaces come off easily due to the mischief of friends, poor tying of the shoe or the shoe might not be as tight as the user wants it. Untied shoelaces will cause people to trip and fall and give difficulties to children who does not know how to tie a shoelace yet. People with arthritic fingers will also have difficulty tying shoelaces. It is also very troublesome to the user when his shoelace is untied as when that happens, the person would have to bend down and tie their shoelace again.
