I recently purchased a pair of Fischer RC4 110's with the vacuum fit off the internet as a replacement for a four year old pair of Solomon Quest Access 80s that I bought four years ago when I was just getting into the sport and was nowhere near the skier that I am now. I received them a few days ago and after trying them on, I've noticed that after wearing them for ~30 minutes, my feet begin to go numb and are red and tingly when I take the boot off. They are the identical shell size(338mm -- Mondo 29.5) as my old boots, so I'm guessing it's partially because I'm not used to a narrower, more performance oriented boot, but I have no way to know if that's for certain or not.
I know that the vacuum fitting process molds the boot to your specific foot, but is the range that it can work with enough to correct for that issue, or should I send them back and try something else? I'm hesitant to have them molded because they're mine for good once I do that, but at the same time they seem to be a great boot (and I got them for a great price) and thus I'd like to stick with them if the molding will solve my issues. I tried to do some research on the molding process and didn't get very far, so if any of you have experience working with it, I'd greatly appreciate your input.
