This is a size 23cm. Purchased at Iwataya, Fukuoka. Worn once or twice, so it's in beautiful condition with no noticeable scratches or stains. Great for swimming lessons in the pool, or when you need easy-to-put-on slip-ons for outdoor play. The edges firmly secure the feet while playing, preventing slips. Plus, it uses a fastener that's easier than straps, so you don't have to worry about the fit. I'm selling these because my child has outgrown them. Thank you for your understanding regarding used items. #NIKE #NIKE Kids Sandals #Kids Sandals
