The Waveformd A-Frame Footstop flips the script by using metal studs and a CNC grip tile to hold your front foot in the perfect position for your next turn, slash or slide. Performance urethane construction (with a familiar skate feel of 86a) removes the vibration translation that comes from most aluminum CNC footstops while the softer urethane feel also keeps the grip studs from being too rigid or harsh on your foot to keep you locked in and comfy adding control to your longboard, downhill deck, surfskate or e-board.
