Warm and waterproof, the Blundstone Thermal Chelsea Boot come to our daily rotation with handsome style and high-quality craftsmanship to get us through cold, damp days. The waterproof leather upper fends off moisture, while Thinsulate insulation throughout prevents our toes from freezing. Cushioned comfort comes in every step thanks to the combination of a removable sheepskin footbed, cushioned midsole, and durable TPU outsole.
