With 400 grams of insulation rated to -40°F/-40°C, the new KEEN Kids Lumi boot has a waterproof EVA shell design. This ultralight boot with cold-weather traction helps little kid legs move easier through winter weather. Made with durable, Waterproof lightweight injected EVA shell and textile upper, the kid's Lumi Boot 2 Waterproof 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.
