I bought this shoes in a size 11 for my 31/2 year old. He wears a 10-101/2 but I thought I'd get as much wear as possible, even into the fall. They were a bit big, but he can wear them as indoor shoes at school when the weather gets cold. These shoe are very nice looking....and you can wash them. We've had many compliments.  I definitely buy them again...in another color of course!
