I have a super wide forefoot and I ended up getting SPK's.
But my bootfitter had me try on Full Tilts too. He said that he could make me some footbeds, blow the shell out and all would be fine. The only problem was that my heel didn't feel secure at all in the Full Tilts. Hence the decision to buy SPK's.
Don't ask NS. Just go to a good bootfitter. They'll know much more about what boots will fit your width foot than most kids on here ever will, especially because we've never seen your foot.
