The UGG Sundance woman's boot features exposed sheepskin and is unmistakably UGG Australia. This boot is extremely comfortable, made with the finest twin-faced sheepskin and features a removable/replaceable fleece insole and a mylar lining that provides extra warmth. The UGG Sundance has reinforced suede heel and toe guards for increased durability, as well as a rubber lugged outsole for extra traction and slip resistance.
