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. Your UGG Classics may fit slightly snug at first, but the natural properties of sheepskin allow them to gradually stretch and adapt to your unique fit. 17mm twinface sheepskin upper asymmetrical topline overlock stitch detailing on seams rear pull tab suede heel counter 17mm sheepskin lining 17mm UGGpure™ upcycled wool insole or 17mm UGGplush™ upcycled wool blend insole sugarcane eva outsole woven label with logo water repellency treatment
