The term 'shoelace alternative' can refer to two different solutions: Velcro (6 letters) and Velcrostrap (11 letters). Velcro is a type of fabric fastener consisting of two strips of fabric, one with tiny hooks and the other with tiny loops. When pressed together, the hooks and loops interlock, allowing for a secure closure. Velcrostrap is a variation of Velcro that uses a strap instead of two strips of fabric. The strap has a loop on one end and a hook on the other, allowing it to be secured around an object. Both Velcro and Velcrostrap are popular alternatives to traditional shoelaces, as they provide a secure closure without the need for tying or untying.
