It's 23.5 cm. My child used these, but they've outgrown them. Purchased in June of this year. Worn 4 times. Worn twice on an outdoor futsal court and twice in a gymnasium. The color is cool and eye-catching. I've listed them as having no noticeable scratches or stains, but there is some slight soiling on the toe of the right shoe. I think they are in good condition. Please purchase only if you understand that these are used items. Popular series: Morelia
