The Ugg boot was a quintessentially Australian product. Australia was said to ride on the sheeps back some decades ago when there were millions more sheep in the country than people, and sheepskin products were extremely common. Sheepskin is an extremely hard wearing and versatile product, and lends itself to production into jackets, boots, seat covers and much more.
Ugg boots were no exception and have been available in Australia for decades, but more recently have become available worldwide. This has resulted in the Ugg becoming a fashion accessory right throughout the world.
The Ugg boot is not a hard wearing boot like a leather boot though, and you need to take a little care with you Uggs. They are a soft boot but made with a hard plastic sole, with the sheepskin sewn onto the sole. The sole is generally hard wearing but the sheepskin sides can be prone to getting dirty very easily, though they can be easily washed.
