My 5 year old has tiny feet. She wears a size 9 for toddlers and even some size 8s fit her. I ordered them at 9 and they just fit. Luckily I ordered her for vacation so when she grows up it's okay. But yes, if your child is an age-appropriate shoe size, I would take the advice of at least one other reviewer and order at least one size up, if not two. I understand this is a Chinese product but I'm not sure if that explains the size anomaly. My daughter is half Chinese and so far dad has small feet.
