I have small feet so I don't have experience about when to get a wide board but from what I've heard a lot of people say, if you wear US 11.5 or bigger you should at least check it out. If your boot has a low profile or your board is naturally wider you might be ok, but i know normally you'd probably want a wide board with US 13 boots. Also consider your style, if you're going to be going fast and carving hard or are going to be in deeper snow, you're going to want the board a little wider to keep the boots from digging into the snow. 153 might work regular since it's not your charging board but it might still be cutting it close. the 15 degree angles help too. just some stuff to think about.
