When and where the UGG boots appear?
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.
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.[citation needed] 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.
