Uggs are funny!
I think the trend started on the West Coast, because of all the surfers who wanted to keep their feet warm afterwards (back me up? Sounds random, but that's what I heard).
Anywho, before they became actual cold weather boots, my entire Jewish-Jappy-Private-High School had them. It was mandatory for admission, I swear. And the only way to wear them was with a skirt short enough to be a tube top.
I got them when I played water polo, because otherwise my feet would freeze. I found when I got to NYC, they didn't work so well in the snow, because they have no traction on the bottom.
Back to the topic...I think Uggs technically are "out of style", but very occasionally, function becomes more important than fashion. Very rarely.
