Thank you. Good to know.
The guy who made my orthotics, now retired unfortunately, used to make custom boots. Peter Morin. His boots were beautiful, and he could make them the perfect shape for anyone's foot.
I asked him why he had become a pedorthist if he made custom boots. The answer was that although he could make boots that fit people perfectly, sometimes his customers just couldn't have comfortable feet in spite of that because the support under the foot was inadequate. So, to make the perfect boot, he learned the trade of a pedorthist (which took enough schooling for a PhD) so he could also create custom footbeds. The support at the bottom of the boot, I can attest, is critically important. Especially when you are really loading your feet and particularly under the conditions tough mountain terrain impose. And for those of you with extra high arches, those custom footbeds are a godsend when for the first time you actually have proper support under your arch and mid-tarsal area. I used to get the equivalent of carpal tunnel in my feet on long backpacking hikes or under heavy loads of meat. No longer, as long as my orthotics last. Orthotics are not just for flat-footed people. Anyone can benefit, but especially those of us with lower than average or higher than average arches.
