The general consensus is that “fug” stands for flying Ugg. Due to the 100% natural sheepskin from which genuine Uggs are made, they are the perfect boot for flying in as they are loose and comfortable and keep your feet at a constant temperature. Thus at high altitudes your feet would remain at a comfortable body temperature. In the 1930s, Australian sheep shearers wore Uggs to keep them warm. By the late '60s, surfers were wearing them to keep them warm on the way to and from the sea. By this point, Uggs were being produced throughout Australia.
5 The original Ugg boot style was made from just three pieces of material: one for each side and one for the soft sole. Ugg boots now come in long,ED Hardy women bags, short and decorated styles and have sturdy rubber outside soles.
6 1978 saw the beginning of the rise of the Ugg. An Australian surfer named Brian Smith took a bag of boots to America and the boot began to gather fans in the American surfing community. The Ugg boot then slowly gathered steam over the next twenty years.
