Bought 8-12 pairs of sneakers in two colors for my 10 year old girl/boy twins who each have small to medium feet. They fit my daughter just fine - at least until she grows up again; but the heel does not reach the heel of my son's feet. For reference, she wears about a 2 and he wears about a 3. So I'd say after a size 13 or 1, put on another sock that they can wear longer; but after size 2, don't waste your money!
