I have the same problem. This year Salomon has three or four boots in a wide width..Also don't forget custom orthotics for a much better fit.
I will spend over 100 days on the hill this year instructing and I could not do w/o the custom orthotics. As far as I know salomon are the only ones making wide boots..chk the new models on the salomon website.
Heat molding the liner along with custom footbeds should alleviate most of your issues. Try em all, some standard width boots run wide so keep an open mind about this..good luck.
I don't like to mention brands but thirty two standard width boots w/custom footbeds work for me.
