Now pretreated to protect against moisture and staining, this classic UGG short boot is a supremely cozy cold-weather favorite updated with an oversized 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.
