Besides Birkenstocks and Tevas, there's perhaps no shoe more polarizing than the Ugg boot.
These sheepskin-lined kicks have earned a spot in recent fashion history—not just because they've graced the feet of some of the biggest names in fashion and entertainment, but because the Ugg brand has seen increased profit almost year after year. That's sayin' something considering the fashion set seems to have a perpetual love-hate relationship with the shoe.
For proof, look no further than our entirely unscientific tracking system of the shoe's popularity among the fashion set. (Note: This is based on the tide of trends rather than sales numbers.)
