Now pretreated to protect against moisture and staining, this classic UGG short boot is a supremely cozy cold-weather favorite updated with an elegant two-tone bow. The plush lining is made from genuine shearling or signature UGGpure, while the the Treadlite by UGG sole provides lightweight cushioning, flexibility and traction. UGGpure is a textile made entirely from wool, but engineered to feel and wear like genuine shearling.
