Whatever winter hiking looks like for you, warmth, comfort, protection, and traction are non-negotiable “must-haves.” So we built an insulated, waterproof, grippy hiker that checks all the boxes. All hike. No compromises. • Warm and Dry: 200g of KEEN.WARM insulation rated to -25°F and a KEEN.DRY waterproof, breathable membrane keep your feet toasty and dry. • Better Leather: Environmentally preferred leather upper is lighter on the planet. • Lightweight Cushioning: KEEN LuftCore technology embeds a lightweight foam core inside the midsole to absorb shock for comfort that lasts all day.
