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 on the inside. The soles of the boots are made from rubber, and the stitching is often prominent on the outside of the boot. The fleece draws away moisture, keeping the feet dry and at body temperature.[16] Today they come in a variety of colours, including black, pink, blue, chestnut, and fuchsia.[17] They are available in both slip-on and lace-up varieties and their height can range from just above the ankle to above the knee.[17]
Ugg boots often have a synthetic sole, although this is not universal. They are available in a range of different colours as both slip-on and lace-up varieties, and they are produced by a number of manufacturers. The natural insulative properties of sheepskin gives thermostatic properties to the boots: the thick fleecy fibers on the inner part of the boots allow air to circulate and keep the feet at body temperature.[16] This means that ugg boots can be worn without socks even in relatively cold weather.Some variations of ugg style boots have also been made from kangaroo fur and leather.[18] There are also synthetic boots. Although derided as "fake" by some in the industry,[19] their lower price made them appealing to large retail chains such as Myer.[20]
