The Classic Ultra Mini features a low shaft height for easy on-off wear. Pre-treated for durability, the design includes a signature sheepskin lining, an ultra-soft UGGplush™ insole, and a flexible, lightweight sole. These boots may fit slightly snug at first, but the natural properties of sheepskin allow them to gradually stretch and adapt to the foot. 17mm twinface sheepskin upper asymmetrical topline overlock stitch detailing on seams rear pull tab suede heel counter medial zipper 17mm sheepskin lining 17mm UGGpure™ upcycled wool insole or 17mm UGGplush™ upcycled wool and TENCEL™ lyocell blend insole sugarcane eva outsole woven label with the UGG® logo
