We're charmed. The UGG® Heritage Lace-Up Slippers take all the goodies from the famously cozy slippers − think smooth suede upper, the warm sheepskin lining, and lightweight sugarcane Ethylene-Vinyl Acetate (EVA) sole − combined with a whimsical, removable mini sheepskin UGG® boot charm. Made for endless comfort and for wearing indoors or out.
