This heel strap converts any shoe into a grounding shoe. You will then be grounded when standing on any conductive surface, such as grass, earth, sand or concrete.
Simply slip the conductive rubber heel strap over the outside of the sole of your shoe, securing with the adjustable quick-release strap, and then tuck the conductive ribbon into your shoe or sock to connect with your skin.
Wearing our highly conductive grounding socks with your heel strap improves the connection to your skin and also means you only have to tuck the conductive ribbon into the top of your shoe, rather than inside your regular sock.
One heel strap (grounding through one foot) is enough to ground your entire body, especially when used together with a grounding sock.
