If you're looking for winter boots I would highly recommend these, having owned Emu boots (not quite UGGS, but much better made than the £10 ones in shops), they aren't as warm as the UGG style boots as they don't have fur throughout the inside as a fellow reviewer has said. The fur trim goes down about 2 inches inside and down at the front. So my feet were colder than in UGG style boots, but can be remedied with some thermal socks. HOWEVER, the ability to walk properly and have a proper sole on them far outweighs this. They also give good grip on the snow which the UGG style boots never did. They are also a lot warmer than normal non-winter boots, especially around the leg where the furry bits are. Although as other people have said they are a bit roomy, am a size 5-6 and went for a 5, however the boot grips well around the ankle and leg so you're not sliding about in them. Plus means that you can wear them with thick socks and have warm feet.
