With a little wider platform than the shark, the M5 is designed for both performance and comfort. We took a twist on our patented concave sole with this design...you'll notice for the first time in Mad Rock history, the concave sole features our flat sole design for optimal overhanging grabbing, it also creates a sharper edge for standing on tiny holds and ledges. The Arch Flex ensures the glove like fit that you've come to expect from our performance shoes, and the new Torque Heel will enable you to exploit rock features like never before. The Power Upper covering the majority of the forefoot adds more than 30% of rubber to facilitate toe hooking and jamming. Great for Bouldering, Sport, Competition, Crack Climbing and the Gym.
