The UGG Australia story begins with one magical material, sheepskin. UGG Australia only select the highest quality Twinface sheepskin available which we truly believe is the perfect material. No other material so naturally keeps your feet cool and warm at the same time. Or, for that matter, is able to bring together cozy and cutting edge in a single pair. Once you have experienced this wondrous material, you'll understand why you have to feel it to believe it.
