The size is 23.5cm. I bought these but they are too small for me, so I'm selling them. I usually wear a 24cm in NIKE sneakers. Purchased online and tried them on at home. New with tags, unused. I will ship them without the box. Black suede material, these are a pair of durable, rubber-soled, mouton boots. - Color: Black - Material: Suede - Design: Mouton boots - Sole: Rubber sole - Lining: Fur insole Thank you for looking.
