K2 first introduced the successful Hurrithane binding with its pliable urethane highback movement five years ago. The updated 2014 Tweekback FS highback shaves weight and takes even more advantage of the tweekable flex and comfort that full urethane highbacks offer. Despite its pliability, it still effectively transfers power to the heelside edge. Upgrades for the 2014 edition include new Pro-Fusion PC durable polycarbonate chassis and new Tool-Less Universal toe strap. The Hurrithanes are truly "skate inspired technology for skate inspired grabs and slashing."
