Real UGG boots or fake? You can tell if your Uggs are authentic by looking for the authentic sheepskin interior. It should have a creamy color and a full texture. Fake Uggs use an artificial fur interior that is grey in color and feels thin. Real Uggs say they are made in China on the label. Fakes claim to be made in Australia or New Zealand. Check for the registered trademark mark (R) on the sole. Real Uggs have it, fake ones don't. Finally, the uppers on real UGGS meet the sole smoothly, with tight, superior stitching. Fake Uggs come together at the sole in a sharp corner.
