The shockliner represents the world’s next generation roller skate by using a patented suspension system for improved comfort and performance. Skaters appreciate the shockliners' low weight and excellent damping characteristics that help to avoid strain on joints and spine. No more numb feet after driving on rough surfaces. Furthermore, the shockliner is able to store the muscle energy and body weight from each step in the spring and give it back as additional thrust for greater speed and efficiency.
