Technogel provides virtually invisible comfort that never goes flat and will outlast your shoes. Guaranteed. These Foot Petals simple and mini miracles 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.
