Never let the weather determine your plans: head out rain or shine in the Classic Mini GTX boot from UGG. This iteration of UGG's Classic Boot is built with waterproof suede and an internal GORE-TEX membrane to keep out rain and snow. Slip into the cozy warmth of their UGGplush lining and insole, and stay toasty in temps as low as -20C. Underfoot, you'll be supported by a lightweight sugarcane EVA midsole and grippy Vibram outsole.
