In short, air force ones do fit true to size. They also aren’t officially labelled as ‘wide-fitting’ shoes but people with wide feet do find them comfortable. People with narrow feet with also find them roomier.
Also bear in mind, the ‘mids’ and the ‘high’ model of the shoe fit a little bit tighter than the ‘low’.
As I always recommend, try them on first.
Many make the mistake of assuming that they all fit the same when they don’t. There are slight differences.
This could be a reason for their popularity, they are a very comfortable shoe that work well for a lot of feet!
