The NatraCure Gel Ball of Foot Cushion Pads help protect and cushion the sensitive ball of foot area. These slim, invisible, non-slip, gel cushions fit comfortably into the front of your shoes to help prevent the burning sensation that occurs in the balls of your feet. Never-Slip Technology keeps feet from sliding forward in your shoes. The self-adhesive backing allows each cushion to be adhered to most materials. Cushions are especially effective in high heels and thin-soled footwear as they distribute pressure away from high-impact areas. Polyurethane gel resists tearing during repeated use.
