Thank you for viewing. There is some sign of use, but I think they can still be worn. I don't know the exact size, but measuring the length of the sole, it looks to be about 12.5 cm, so I estimate it to be around 12 cm. *Please check my profile and photos before purchasing. I usually ship within 1-2 days. There may be cases where this is difficult due to circumstances. I will do my best to pack them neatly. If you have any questions, please feel free to ask. The shipping method may change.
