Climbing shoes Bouldering shoes Brand: EB European size: 31 Approximately 19.5cm For kids Purchased as new, used for about a year (around 20 times), and selling because my child outgrew them. My child's actual foot size is about 19.3cm, and they usually wear shoes of about 20.5cm. I hope this helps as a reference. There is some dirt on the soles and uppers, but I think they are still in good condition for use. Since they were worn with socks, I don't think there is any noticeable dirt on the inside.
