I had a good experience with Scott Dudevoir at Cole Sports at the PCMR base. He's on the EpicSki list of Master Bootfitters. Here's the write up from the master bootfitters thread.

Additional Comments: I had a pair of Salomon Verse TF boots, bought in North Carolina, that still hurt after 6 days of skiing and several adjustments. Because of my severe pronation and flat arches, my home shop advised me to get Superfeet Custom footbeds on my trip to Park City. (No one around here makes those.)
First thing in Park City I met with Dude, who I'd contacted previously by phone and email. He spent several hours evaluating my feet and boot fit, trying several other boots, then making my footbeds. He felt the Verse shells were too big for me and determined that the Salomon Evolution 9.0 was the best fit. He suggested I might get them cheaper from the store in NC, have them shipped to Park City where he could get them properly fitted, and he would UPS the old boots back to NC. (I was impressed!)
After skiing a few hours in the Verse TF boots with my new footbeds, I still had pain - and too much movement. I bought the Evolution 9.0 from Dude and made a few runs down Payday that evening... and could not believe the improvement in my skiing control and comfort. The new boots were more comfortable on the first run than the old ones after 6 days of skiing. By the third day in these boots I was wearing them comfortably for 8-10 hours at a time (such as taking the bus to Alta.)
During my two weeks in Park City I was in Cole Sports many times for accessories, tuning and waxing, and for some minor adjustments to the new boots. Dude and the staff were friendly, helpful, knowledgeable, and always eager to provide a high level of service. I was greatly pleased with my experiences there and recommend them highly.
