This Wai Wai base pad covers windsurfing mast bases providing the ultimate foot protection! This is the perfect windsurfing accessory for any level of windsurfer; it is especially great for short board use and freestyle boards as your feet are closer to the mast base. We use the Wai Wai in our demo fleet and it is a guaranteed foot saver for those mis-steps! This mast base pad is made up of high-density foam and is compatible with u-joint/hourglass and tendon universal mast bases.
