You really should try them on, but I understand in some situations it might not be possible. If you're willing to shop online and can find a retailer with a no-hassle return policy, I would recommend Salomons. I have similar, wide feet and just upgraded from Burton Motos to Salomon Faction BOAs. Burton, Salomon, and ThirtyTwo I've heard are cut on the wide side, so if you're a tough fit even after trying ThirtyTwo, then maybe Salomon's Wide models are the way to go. My Factions aren't a "wide" model, and are very comfortable. While I wear 11D sneakers, my boots are 10.5. Maybe try the Salomon Synapse Wide... LINK
Good reviews on most sites, and good reviews on this forum as well.
