There are a couple Full Tilts that are made for wider feet. Check out the Booter (Item # FLT0060) and the High Five (Item # FLT0062) Both of those boots have a last width of 102mm as apposed to the 99mm last width of most Full Tilts, including the First Chair.
The High Five will have the same Intuition Pro liner that this First Chair has, however, it will be a little bit softer. Just put those items numbers in the search bar and check them out.
Hope this helps!
