I've skied around 40-50 days in my "new" boots with varying degrees of comfort, and ongoing tweaks by the bootfitter who sold them to me. But last week, right in the middle of a week-long exam course, a long-simmering but hitherto benign blister on my little toe imploded and became nastily and unattractively infected. After cramming this swollen thing into my boot for the last two days of the course, I am still reluctant to wear anything (including a sock) on that foot, but I did go in and see my bootfitter today. The centre of the blister aligns suspiciously with a seam on the boot liner, but my bootfitter says this shouldn't have caused the blistering without movement, and he wonders if the shell is slightly too wide at that point, allowing my foot to move while skiing. It certainly doesn't feel loose -- if anything it is still uncomfortably tight, even in a flexed position. I don't feel as if I have any movement while skiing. The thought of going any smaller in a ski boot makes me squirm.
He's going to try some Palau boot liners (taken out of a pair of new but replaced-under-warranty boots) and heat-fit them once my toe returns to normal to confirm (or otherwise) if my liners were to blame. I tried on several different brands of ski boot (on my unaffected foot) in the store today to see if any fit better than my current boots, but they were all worse. We went through a fairly long and exacting fitting process when I bought the boots last year, and they were actually very comfortable and supportive for at least the first half of the season last year. When things started getting uncomfortable, I had a bit of work done to them, including getting new custom footbeds, having a piece of the tongue cut out, some widening of the forefoot on the affected boot, and some tweaks to the footbeds. It was starting to get better ... But I think the bootfitter is flummoxed by this latest thing.
Any knowledgable suggestions as to what the problem might be?
For reference, the skiboots are Salomon Quest 100W in a 24.5 shell. I would wear a 25-25.5 shell in other brands.
