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.This product was made in a factory that supports women in our supply chain with the help of Reimagining Industry to Support Equality (RISE). This collaborative initiative creates partnerships with brands like ours to empower and educate women in the workplace. Waterproof. Waterproof membrane bootie construction. Waterproof leather.
