We're celebrating 25 years of the Adirondack, and what better way to do so than by creating an all-new, cold weather champion? Our Adirondack Boot Tall XXV is an ultra-capable winter boot that combines elements of two of our faves: our Adirondack and Butte boots. It features fully waterproof genuine leather and suede, Xerogel insulation that keeps you warm in temps as low as -32ºC, and a tall shaft for even more protection. Infusing UGG® heritage with modern materials, this new edition of the Adirondack Boot still delivers the same Feel of UGG® you already know, love, and crave. Take it to the mountains or the city streets – this boot is ready for wherever winter takes you.
