I love love love my Uggs!
Super comfy and really warm. I did find that I had to buy one full size smaller than what I normally wear (which is a size 7US) so I went with a size 6US. I have a pair in black and pink. When I wear my black ones without socks, my feet come out 'stained' black from the insides...this does wash off fairly easily but can present an embarrassing problem if you wear these out and then go somewhere and have to remove them!
While they may not be the most stylish of boots and the trend seems to have passed long ago, I will be wearing my Uggs for years to come!
