So I decided to put uggs on my christmas list (I'm in CO and after the cold this week, I decided I need something to keep my feet warm!). I was looking at them on zappos and trying to figure out the difference between the ultimate and the ultra... also, do you girls think they're easier to walk in/keep clean than the classics?
I think the Ultra is your best bet. The bottom of the shoes look like it has better grips and since you're walking in snow, it's definitely better than the classic. I don't have Uggs myself but from the pictures, thats what I'm guessing. You should buy some suede protector to protect them. Hth!
