The label says UK6.5, which is 25cm in Japan, but I was wearing them with insoles (I'm 23.5cm). Black UGG mouton boots. The inside of the boots is lined with fluffy mouton on both the top and bottom of the foot, so they're very warm. The size feels like it can fit from 23.5cm to 24.5cm. I've taken photos of any areas of concern. They've been used, so there's a feeling of wear, but I think they'll still be great.
