Perfect foot changes every time. The pad’s EVA Diamond grooves stick to your feet no-matter-what because its pattern is milled, yes milled. Instead of thermoforming a pad which results in inferior rounded profile edges, we machine ours into a remarkable no-slip pad. And it feels great under bare feet and booties too. The 3-piece, self-stick center set comes in two designs. One fits the 720. And the other fits the Ripper 3 or Green Room (including recesses for the straps). So, please order the right one! When you’re tired of waxing, try the CORE Front Traction Pad. You’ll be glad you did.
