My 8 year old daughter wears size 2 street shoes. I read so many reviews saying to go at least 1 size up. I ordered 3.5 first but they were huge. I sent them back and got a 2.5 instead. Still a bit big but they don't fall off and there is room to grow. Buy shoes in the size your child wears in regular shoes.
