just bought myself some of these by skechers, only £24 and they are lined with real fur.
they only have sizes 2 and 3 left BUT the sizing is big. i read the reviews and ordered a size 2, am normally a 4, but the 2 is plenty big enough, 3 would have been too big.
ps, i don't actually like uggs, won't be wearing them out, got them for wearing at home as slippers, our house gets really cold in the winter, wooden floors everywhere!
