Guys. Thanks for your quick responses. Here's some more information.
I'm 46 years old, 5'10", 190lbs. I've skied off and on since I was preschooler. I'm currently a solid level 8 (PSIA) skier and am working on improving. I live in Idaho and ski here, Utah, Wyo, and occassionally in Montana, and Alberta. I ski regularly with some very good skiers including a 30+ year Level III PSIA instructor and coach. I ski all over the mountain and have a race influenced style. However I can rip the bumps better than many of racer style buddies.
My boots are Dolomite X10 Rage; 100 or 110 flex; 98 mm last; 318mm sole length. They are 27.5 and I wear a US 10 in street shoes. My feet measure 100mm at their widest point--not particularly wide, but high in the instep. They measure 272mm in length. I've owned them--the boots-- for 3 seasons, 2 of which I skied pretty hard (25-50 days each).
My original complaint early last season (after having skied 2 seasons reasonably comfortably in them) was excruciating pain along the outside edge of my feet. I didn't feel like I was standing flat across the width of my boots. My feet cramped badly across the width. I felt the pain especially along the outside of my feet, like my weight was being carried on the little toe side of my foot, not across the full flat surface of my foot.
I do have high volume feet that are flipper shaped--quite wide across the base of the toes and moving back toward the heal. I also have high insteps and low arches, but not totally flat feet. Without the liner, standing flat in the shell with my toe at the front, I have about 1cm of space at the back of the boot.
The fitter started by aligning my cuffs which had not been done previously. My uppers very nearly touched the outside of my shins and left a large gap on the inside of my shin. Apparently I'm a bit bowlegged and probably supinate some. The fitter aligned the cuffs so my tibias are centered in the uppers.
After aligning the cuffs he went to work to give me a little more width. He punched the outsides of each shell fairly agressively--but more on the right foot. Perhaps this was too much. I've wondered if perhaps this boot is too big now. Is it possible to reheat and reduce the effect of a punch? I don't think I could wear a smaller shell size.
In the effort to be conservative, the fitter left me in my stock footbeds, anticipating that they might needs some attention later. The relative improvement in my comfort was so great, I didn't think anything else was necessary until I noticed the gripping problem late in the season.
The fitter did not sell me these boots nor has he looked at them since I noticed the gripping problem. He was a newcomer to the shop where I bought them so I'm sure he didn't want to say anything too negative about the original salesman. However, he did say that the boot wasn't a bad starting point for my particular foot.
Hopefully this is the type of information that will help. I know a picture is worth 1000 words and seeing in person is worth a lot more. any help you can offer is appreciated.
