The Keen Women's Revel IV Polar Winter Boots combine the agility of a light hiker with the warmth of a puffy coat. They come with 200 g of insulation, heat-trapping materials underfoot, and exceptional grip on snow and ice. Made from waterproof leather and performance mesh materials, these boots feature metal eyelets for added durability, thermal heat shield insoles that capture warmth and compression-molded EVA midsoles for cushioning. The Keen Women's Revel IV Polar Winter Boots were built for women, with active, frigid days in mind.
