It'll bite the tiniest of numbs, hunt the slimmest of ledges and give you the needed edge to kill the hardest routes. The Mad Rock Shark 2.0 takes advantage of the original shark's Last, but brings new killer features to work. Call this shark bionic. With Arch Flex technology providing an aggressive yet comfortable fit, this shoe puts high performance R2 rand rubber on the rock. This high performance rubber hugs the foot without acting like that overly aggressive "friend." You know the one. It's the same friend that painfully locks onto your foot when you slide into some other high performance climbing shoes. Loose that friend, at least where your feet are concerned, and slip into a shoe as hungry for the climb as you are. Slip into a shark.
