Jeff Gray, Superfeet Guru and Master boot fitter, at work.
I answer more questions about boot fitting than anything else here on Cold Thistle. Happy to do it. But my feet are not your feet, so some times it is not the best answer for you specifically. It is just my experience and a guess as to what might help you. I have a much bigger post to write up eventually on all of this. Hopefully that will answer many more questions and fill in the details.
But let me cut to the chase here. Don't wait on me. If you need an insole (and most do) search out a Superfeet dealer.
If you ski....search out a dealer that has the knowledge and experience to do the Kork Custom foot beds.
No BS here...30 years ago Jeff fit me for a pair of custom Korks @ the Vegas ski/snow show and literally changed my life in the outdoors forever. I'll eventually write more, but Korks might be the additional help you need as well to up your own skiing. It really is worth the effort to search out a boot fitter that does Custom Superfeet Korks. They were without a doubt the best technology available for years. I have heard the arguements from both sides and seen the results as well from most everything available since then and IMO... done right, the hand made Korks are still the best technology available today in a ski boot.
