The Keen Men’s NXIS EVO Waterproof Boot – What we 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 we took the room-for-your-toes comfort, protection, and stability of our iconic hiker and gave it a running shoe feel with a waterproof, engineered knit upper and all-terrain tread.• Famous Comfort Fit: 18 years in the making, our original fit is built to hold your heel firmly in place and give your toes room to spread out.• Iconic Toe Protection: Move fast over a variety of surfaces with confidence, not stubbed toes.• All-Terrain Tread: Our proprietary horseshoe tread pattern grips from heel brake to toe roll.
