UGG boots became popular among the wool shearers in 1920s, when shearers would take a piece of wool and wrap it around their feet to keep them warm in the colder months. Shearers joked and called them "ugly boots" and with good old-fashioned Aussie slang, quickly got shortened from shearer's ugly boots to UGG boots.

UGG boots can be worn in winter or summer. in cold weather the plush fleece of UGG boots provides an insulating layer by trapping body heat. In heat of summer, the natural fibers of fleece will actually cool the feet.
