These are quite slim. The leather is soft and very comfortable to wear, but those with wider feet may find them tight. The size is listed as 23 cm, but I think they fit a little smaller, like a 23. As shown in the fourth photo, a cushion has been applied to the arch of the foot. The straps in the fifth photo can also be used.
