A new technology designed to help prevent blisters and hot spots before they start and to provide relief and comfort if you already have a blister. The science behind Blist-O-Ban is its patented dome, which mimics a blister. It glides smoothly in all directions, deflecting friction and rubbing forces away from the skin. It redirects pressure away from hot spots, preventing a blister from forming. Blist-O-Ban bandages are also great if you are breaking in new shoes or boots. The bandages are ultra-thin, breathable, water-resistant and latex free. Includes 4 adhesive bandages.
