Foot Petals Pressure Pointz are multifunctional shoe cushions designed to help prevent blisters and to provide supreme comfort in virtually any area in your shoes. These Foot Petals help relieve painful shoe pressure. Pressure Pointz have trimmed edges so the cushions won't roll and curl with foot friction. They're 1" in diameter to precisely cover any points of pain, and they're 1/10" thick so they're virtually invisible. All Foot Petals shoe cushions are made from PORON Performance Cushioning. PORON repels moisture, bacteria and odor, absorbs shock, and is available in colors that blend with shoe colors. PORON cushions will never lose their shape and will last the lifetime of the shoe.
