The UGG Boots are traditionally made from sheepskin. The wool is tanned into the leather, and the upper part of the boot is assembled with the fleece. The soles of the boots are made from rubber, and the stitching is often prominent on the outside of the UGG Sundance boot,so that looks line feels strong, concise and hale. The fleece draws away moisture, keeping feet dry and at body temperature. Today they come in a variety of colors, including black, pink, blue, chestnut, fuchsia, and so on. Also they are available in both slip-on and lace-up varieties.
