Flexitol Blistop is a blister prevention spray that creates an invisible layer of film to protect the skin on feet & hands where blisters can occur from friction. Convenient & easy to use, Flexitol Blistop stays in place & won't rub off easily or leave residue on your socks & shoes. It acts like a second skin & is totally transparent so you are able to wear the shoes of your choice & feel confident & pain free all day long.
