Runs a tiny bit larger than the other size 7 sneakers we bought but not so large that I would go a size down. The velcro is great and tight so even though they fit a bit big his ankle and toes are secure. Great quality. The only con is that his feet get a bit sweaty (with thin socks) in them and his does not happen in the Dr. scholls sneakers. He walks and runs well in them. Does not complain so they must be comfortable. Son is 15 months old and wears a size 7.
