I am (5' 8", 190#), have small normal width feet (26.0), giant low muscular calves, high arch/instep, and my weight naturally rests on the outer edges of my feet. My feet naturally point directly straight ahead. I have to work hard to keep my weight "flat" on the skis and also to control the inner edges in turns.
The work that I had done (in order was):
had custom footbeds made,
had heel lifts under liner,
had back "spoiler" removed
had liner cuff enlarged
experimented with padding around Achilles tendon to (unsucessfully) prevent heel lift,
had back of boot shell cut down to level with the top edge of the top buckle (still about 2-3" too high).
Currently, I have pain where the boot shell digs into the back of my calf, but I can't have the shell cut any lower and still maintain the structure of the boot. I also have pain on the top of the instep and cramping in the ball of my foot. My heel won't stay down, because as I flex my legs for the turns, my calves contract/bulge and mushroom out the top of the boot and my heel lifts putting all of my weight on my instep and ball of my foot (like I'm crushing the arch).
Any ideas on where to begin with new boots? There are very few boot models I can even buckle, let alone try at home for a good fit without major modifications. What order of importance do I look for fit items (what fit items can be modified easily and what cannot?) Someone (non-professional) suggested rear-entry boots - Do they even still make them???
Are there any things I should look for and have done when purchasing new boots/bindings/skis setup for my particular situation with regards to getting my weight more even on the skis and being able to control the inner edges? My boots/binding are at the recommended position on the skis, but I feel like my CG is too far back (or is that an issue that will resolve with boot fit?)
I am in the Albany, NY area and looking for a good boot fitter, but I want to go in ready with information to help get a good fit.
