Wearing the Mad Rock’s Demon 2.0 Climbing shoe is a testament to your commitment to ultra-performance. A new material called Power Flex creates an upper with a tight, glove-like fit but without the pain than can be associated with other climbers. Plus an innovative rubber concave sole creates a cup that you can use to grab at features like a hand. And to keep life more comfortable once you land, a hemp foot bed controls odors while also minimizing stretch.
