Worn only once. This is a collaboration between Reebok and The Animals Observatory. There is some soiling on the soles as they were worn for a short period of time. They are 12.5cm, but my son, who wears New Balance 13-14cm, was able to wear them. Even when he was 12.5cm, he could wear them if the laces were tied, but they look quite big. I am also selling other kids' sneakers.
