Regarding the size, I believe it was 23.5 cm, but there's a possibility it could be 23 cm. Purchased new from a store. Used about 5 times, less than 10 times in total. The soles and undersides are scratched and dirty, but the rest is in good condition, I think. There is no original box. I've been accustomed to wearing sneakers for over a decade due to raising children, so I couldn't get used to these and am selling them. Please understand that these are used items before purchasing.
