This durable, comfortable hiking boot will take you anywhere, whatever the weather. Two types of insulation cut the chill, and the outsole is designed to holds its ground in icy, slick conditions. Made with durable, waterproof leather and featuring a moisture-wicking lining, the Men’s Revel 4 Mid Height Chelsea Boot is built off KEEN's traditional wider footwear form. KEEN products are consciously created using a natural, pesticide-free probiotic-based technology called Eco Anti-Odor for breaking down odor in sweat, PFC-free water repellent (in applicable styles) and leather sourced from Leather Working Group (LWG)-certified tanneries. KEEN makes shoes to make a difference. From the products it makes, to the actions the it takes, KEEN inspires people to live and work monumental every day. As a brand born for life outside, KEEN has a responsibility to protect and conserve the places where all people live, play and work.
