They are undersized. I usually wear a size 10.5 but ended up buying a size 12. I would probably be more comfortable wearing a size 12.5. I ordered my true size first. Too small.
Pros
Que están super comodos pensé que iba aa estar muy duros pero no, están bien.!
Cons
I've worn Vans most of my life so I know how they usually fit. They weren't marked as narrow, but they're definitely there.
