The Mad Rock Shark III Climbing Shoe gives us an aggressive fit without the pain thanks to its molded construction. The patented concave sole eliminates dead space under our curled toes, which allows us to really dig and pull with the toe and delivers power-generating support without the addition of a midsole. The only midsole here is directly under the big toe for added support when we're standing on microchips. On top, the hidden elastic tongue allows for a very generous toe patch that features knuckle bumps for optimal toe-hook performance. And in the back, the thicker heel ridge delivers bomber support on aggressive heel hooks.
