The UGG Women's Adirondack Boot XXV Boots celebrate 25 years of winter-ready style and performance with a bold update to a classic. These boots combine waterproof leather and suede with advanced 3M Xerogel insulation to keep feet warm in temperatures as low as -32°C. Featuring a higher tongue height, cuffable shaft, and secure lacing, they provide superior protection against snow, ice, and slush. A sugarcane EVA midsole and Vibram® ICETREK outsole offer reliable cushioning and traction for city streets or backcountry trails. Lined with plush curly UGGplush, these boots maintain the legendary comfort and heritage feel that UGG is known for, while eco-conscious materials add a modern, responsible touch.
