I detest them for the fact some people walk inwardly on them but having said that I supervise at lunchtime in a school and would imagine them to be superb for standing around in cold weather in the winter.
it's the way they get trodden down (walking inwardly as Fimbo suggests) that looks so horrid...mind you I loathe Crocs too and I have a dislike of those silly plimsolly things teenagers wear (but love Converse - now those have style)
I have the fake ones. OK, they are not the most gorgeous things in the world and I only wear them when messing around outside....but they are so cosy and warm. I bought another fake pair the other day to use as slippers in the house.
Not since the dreaded Croc has there been such a 'Marmite' item of footwear!
Love 'em. Comfy, warm, practical and I think they look great with skinnies or leggings/thick tights and a dress or long top. As I've said on other threads, my personal 'Urgh!' boot is the Fly London-style ones. make even the daintiest of wearer look like a honking great club footed oaf.
I had two pairs of fake ones last winter but they had soles that may as well have been made out of Oasis. If it rained whilst I had them on my socks were absolutely soaked. If I get any more this winter they will have to be the kind that cost more than £8 I think.
The genuine Uggs (meaning Decker/Ugg Australia) don't have the inwards rolling thing - that's the cheapie ones.
I have four pairs of Uggs and they are perfect winter footwear for me. I like having jeans tucked in so the bottoms don't get wet and yukky. I like the way they look. My feet have never gotten wet even in rain. They clean up nicely if I get stuck in a muddy field. They are lovely and warm but never hot. I'm a sucker for sheepskin between my toes.
So that's why for me. Although I do love boots in general and have lots of other pairs/styles too but these are my staples
