Full-grain leather and suede uppers Recycled felt lining Removable, washable liner Bonded felt frost plug midsoles Vulcanized rubber soles To elevate the Women's Joan of Arctic Premium Boot above its other Joan boots, Sorel gave this boot a full-grain leather upper and waterproof construction. Inside, the Joan of Arctic Premium Boot feels as warm and comfortable as your favorite pair of slippers, and, on the outside, it looks and acts the part of more serious winter footwear. Even when temps dip below zero, this boot will protect your toes while you shovel the steps, conquer parking-lot snowbanks outside the store, or wander around the resort on a chilly night in February.
