These are perfect. This style is absolutely beautiful. Works great. good quality. Previously I purchased the Heely's that have two wheels, and the salesperson told me that those run small and that I should buy two sizes larger. He was right. However, the Heely's that only have the single wheel, don't run as small. My son wears a size 12 and I purchased a size 13. The size 13 was a perfect fit, with just enough wiggle room for the shoes to fit for a while. My 6 year old loves them.
