PhysiFeet Invisible Gel Dots are clear gel dots, which can be placed over pressure areas, where footwear rubs or irritates the foot. They are great for painful bony prominences, areas of sensitive skin, and known 'rub' spots where blistering may occur. They are easily placed anywhere in the shoe, with the sticky side to the shoe. The gel dots protect and cushion the foot. They are thin and small and fit easily into slim fitting fashion shoes. They are transferrable between shoes as well. When the stickiness reduces, simply rinse the dots under warm water and leave to air dry and the tackiness returns.
