The Bone Stomd Pad gives your snowboard boots wonderful grip. It's great to use as a target for your grabs. If you have something to aim for when working on your grabs, it is a bit easier. The Bone measures 10" x 1.125" and there is 1 per pack. Foam stomp pads are lighter and have more flex than a hard plastic stomp pad. Foam squishes into the tread on the snwoboard boots and creates a solid bond.
