These are UGG brand sheepskin boots. I bought these a few years ago when I went to Australia, and I was particular about getting ones made in Australia, not the American-made ones. The tag on the back is also very rare, and they are genuine. However, I've kept them in storage because I didn't want to get them wet in snowy areas, so I haven't worn them much. There's no size marking, but I bought them thinking they were a 23cm. The fur hasn't been crushed, so they feel snug at first, maybe a little tight, but it's said that they will break in. They might also fit someone who wears 22.5cm. I've only worn them a few times for short periods. Thank you. Available for immediate purchase.
