What you love most about hiking fast is experiencing more things. More sunrises from the overlook, more high fives at the summit, more post-hike tea with friends back at the parking lot. And more terrain — asphalt to trail to scree to stone steps. So Keen took the room-for-your-toes comfort, protection, and stability of the iconic hiker and gave it a running shoe feel with a waterproof, engineered knit upper and all-terrain tread. 18 years in the making, Keen's original fit is built to hold your heel firmly in place and give your toes room to spread out. Move fast over a variety of surfaces with confidence, not stubbed toes. Keen's proprietary horseshoe tread pattern grips from heel brake to toe roll. KEEN.DRYA waterproof, breathable membrane that lets vapour out without letting water in. Perspiration and moisture naturally produced by the foot are able to escape, while at the same time keeping the wet out and the feet dry.
