Greepers are versatile shoe laces that stay tied once applied to shoes or trainers. Once the laces are threaded through the shoe eyelets they can be fastened by using the toggle, then loosened by pulling on the release tab. They are therefore quick to release and to tighten up again. The quick-release shoelace conversion is ideal for school shoes or sports. As the laces are rigid, they provide a stable fit for the wearer. Used widely by disabled athletes and helpful to anyone who has difficulty fastening laces.
