My last pair of of vans happened to be 13's although I am a 12 and they fit well for 4.5 seasons....
I was more worried about the camber style boards I'm looking at for the uses I'm intending on
Got it. we want to stay clear of boot size for a moment as it will not factor into your board choice. If you could get an actual foot measurement that will help a lot in choosing a specific board.
That will be an awesome start.
