Deckers solicited endorsements from celebrities such as Kate Hudson, Sarah Jessica Parker, Cameron Diaz, Leonardo DiCaprio and Jennifer Lopez, and product placements in television series such as Sex and the City, and films such as Raising Helen. This marketing campaign "led to an exponential growth in the brand's popularity and recognizability." The company reported US$689 million in UGG sales in 2008, almost a 50-fold increase from 1995. Deckers aggressively pursues sales of ugg boots by Australian traders overseas. In 2010, worldwide sales of ugg boots by Australian manufacturers combined equalled only 5.9% of Deckers "UGG"-branded sheepskin boots sales, with UGG dominating the world market. Design Traditional Australian ugg boots are made from sheepskins with fleece attached. The fleece is tanned into the leather and the boot is assembled with the fleece on the inside. Some ugg boots have a synthetic sole, commonly made from Ethylene-vinyl acetate (EVA). The stitching is often prominent on the outside of the boot. The natural insulative properties of sheepskin gives isothermal properties to the boots: the thick fleecy fibres on the inner part of the boots wick moisture and allow air to circulate, keeping the feet at body temperature and allowing the boots to keep feet warm in cold weather and cool in hot weather. Produced by a number of manufacturers, they come in a variety of colours, including black, pink, blue, chestnut, and fuchsia. They are available in both pull-on and lace-up varieties and their height can range from just above the ankle to above the knee. Some variations of ugg style boots have also been made from kangaroo fur and leather. There are also synthetic boots. Although derided as "fake" by some in the industry, their lower price made them appealing to large retail chains such as Myer.
