UGG Sandals

Since humans first cultivated sheep, cultures have made soft sheepskin boots.Their popularity diminished once leather tanning of more durable leather products like cowhide increased. Unlike cowhide, the sheepskin is soft and easily abraded, limiting it to gentle use.[citation needed] Sheepskin boots gained in popularity as a result of World War I and World War II, when they were popular with aviators because of the need to maintain warmth in non-pressurized planes at high altitudes. An exhibit of a WWI aviator's outfit in the Canadian War Museum cites the term "fug" boots. Ugg boots have also been popular with surfers and competitive swimmers since at least the 1960s, for keeping warm while out of the water.Uggs became ubiquitous among Southern California surfers and Southern California downhill skiers, and from there, uggs were popularized by Hollywood into the American mainstream and later the worldwide market.

Ugg boots (sometimes called uggs or ug boots) are a style of unisex sheepskin boots lined with wool on the inside and with a tanned outer surface. Ugg boots often have a synthetic sole, although this is not universal. Uggs have been considered a fashion trend since the early 2000s.

In the Arctic and China, sheepskin boots have long been popular with people in rural occupations (such as sheep shearers, who have ready access to the raw materials needed to make them). They are traditionally used for skiing.Their popularity increased as a result of World War I and World War II, during which they became popular with aviators because of their need to keep warm in unpressurized planes at high altitudes.Emu boots have also been popular with surfers and competitive swimmers since at least the 1960s, for keeping warm while out of the water.
