These shoes were mainly used by my wife at the gym. There are some scratches and dirt from use, but the soles are not excessively worn, and the pump-up tightening mechanism still works, so I think they can still be used for a while. They are recommended for those who like the feeling of a snug fit. The size is 23cm as indicated, but since everyone's foot shape is different, I will not accept claims such as "they didn't fit" or "they were too big." Please purchase only if you understand that these are used items and are being sold online.
