UGG Classic Mini Size 6. The shoe box says 23cm, but they fit me perfectly at 24cm. If you wear thick socks, I think 23 or 23.5cm would be a better fit. I've worn them with care, so there's no noticeable flattening of the sheepskin. There's a slight color change typical of suede, but it's not very noticeable. I'm selling them at a low price, so please understand. m(__)m
