i would say that they are not the real thing, they don't look as good quality and the writing on the back looks different than it does on my real ones.
i would say that if you are going to get some Ugg's to definately get the real things, they are so much more comfortable than the fake ones that are around, i got a pair from claires accesories and they are starting to fall apart only after a month or so.
you can get winter sole ugg boot's which are the kind i got and i would highly recommend them.
I would try looking in TKmaxx though since last year i managed to pick up a pair of pink short style EMU boots for about �20 which are australian and basically the same as UGG's, but the quality's not as nice but they haven't started falling apart yet! x
