Flicks like sandpaper but won't rip your shoes. This Non-Abrasive rubber griptape measures 9" x 33". While sandpaper uses abrasion, DKL Griptape uses frictional forces such as molecular adhesion and the plow effect and is similar to the rubber found on ping pong paddles. DKL Griptape won't rip your shoes because it's made from rubber.
