Plus, they are nearly invisible — so you can use them discreetly. And because they are sweat resistant, your active lifestyle won’t get in the way of taking care of your blister. Advanced DURAGEL Technology uses a unique gel cushion that is thin and flexible. The cushion conforms to the contour of your skin and is nearly invisible when you wear it, making it very discreet. Helps prevent blisters by reducing the friction and shoe rubbing that cause them.
