ski boot blister question

I have a recurring blister spot in my AT boots.  After a multiday tour across a lot  of flat areas last weekend, I ended up with a large open spot where the blister tour off (ouch!)  The spot is on both feet, on the inside of my feet, above the middle/rear area of the arch.  Otherwise, the boots (Scarpa w/ molded Intution liners) fit my feet great.  Wondering if anyone else has dealt with this successfully - perhaps having a bootfitter punch out the shell a bit in that area?  Or maybe just switching to a lower volume insole?  (I'm currently using green superfeet)

You could probably have the shell punched a bit, but you'd want to chat with someone versed the subject. Jim Mates at Custom Boot Service has a good reputation. A temp solution could be to just prep the area of your foot with Leukotape prior to your tour.

JQ has it right. Take em to a quality bootfitter, you won't be sorry. Lots o shops offer free lifetime tweaks once you have had them fitted once.

If you need temporary immediate relief, go with the tape. If you can't get it to stick because your feet sweat, find some benzoin tincture. I use the individually packaged benzoin tincture soaked swab sticks. No muss no fuss.

I find that I have blisters on most multiday tours, no matter how well the boots fit.

Sometimes an easy fix can help as in reducing the size of your ski sock so it fits snugger with no room for friction, as if your size is large 9-12 then switch to a medium. When doing this you will be surprised how easy the smaller sock fits and for me at one point where I had a blister experience it solved the problem.
best of luck

spot is on both feet, on the inside of my feet, above the middle/rear area of the arch.

Similar for me after long climbs. I have been having a bit of luck applying chap stick to the skin in the area in question beforehand. My girlfriend insists that I carefully record which chap stick is used in this manner, and to never consider using those sticks again after they have been infected by my feet... but hey... my feet blister a bit less.

Thanks for all the good suggestions! "Blister gear reviews" can take on a whole new meaning here.
