Blending high-performance technical features with UGGextreme™ comfort and maximalist style, this winter weather snow boot is ready to take on winter weather, rated to withstand temps as low as -32°C. It's crafted from top-quality waterproof leather and features an internal GORE-TEX layer that is waterproof yet breathable. The canvas collar is filled with responsibly recycled polyester featherless down and can be cuffed or worn up for even more defense against the elements. The interior is finished with UGG's signature UGGplush™ blend for a soft, cozy feel that is unmistakably UGG. The midsole is made from renewably sourced sugarcane and finished with a Vibram® ICETREK outsole for enhanced traction on slick or icy surfaces, from the streets to the slopes.
