Speed hiking isn’t about going fast. It’s about experiencing more things. The terrain encountered is more varied — asphalt to trail to scree to stone steps. So, we took the room-for-your-toes comfort, protection, and stability of our iconic hiker. The Men's NXIS EVO Mid Height Waterproof boot is built off KEEN's traditional wider footwear form. KEEN products are consciously created using PFC-free water repellent (in applicable styles) and leather sourced from Leather Working Group (LWG)-certified tanneries. KEEN makes shoes to make a difference. As a brand born for life outside, KEEN has a responsibility to protect and conserve the places where all people live, play and work with no ceiling. KEEN is committed to ensuring our products are free from manufacturing and material defects for one full year from the day you buy it from an authorized KEEN reseller. Some limitations apply. For details, be sure to carefully read the terms and conditions of KEEN’s warranty policy.
