My son loves his Heelys but they run really small. In normal shoes, he wears a 13 and has room yet. He is only 6. I ordered size 13 and size 1 and the 13's hurt his feet. His toes go all the way to the front. When you order, order one size or more bigger than your child wears. Thankfully I ordered the 1's so there was no disappointment on Christmas morning. They were easy to put together and the wheels turn super smooth.
