onenerdykidThirdly, the Superfeet Green might not be the right thing for your foot. In my experience, Superfeet don't work well for many feet and actually can make things worse. So, definitely get a second opinion on if they are the right thing for your feet. As you said, customs are great but they are expensive and fully dependent on how skilled the person making them is.
If the issue truly comes from a lack of volume, a boot-fitter can grind the boot board (piece that lives under the liner, in the shell) down to make some space for your high instep.
I'm confident that the SuperFeet I am currently in are serviceable. I don't have any arch, forefoot, muscular, or structural pain. Believe me, I have felt that pain in previous boots and these are virtually pain free. The only "pain" I have comes from being constricted. Perhaps I can tinker further with the tightness of the power strap & buckles. Sometimes I find that I'm cranking my strap down for the first couple runs down some hairy terrain, where I am really relying in the boot for performance, and I end up going numb in an hour or so. I seem to prefer a performance fit, so I guess some of this discomfort is to be expected.
i wasn't suggesting that I modify the face of the footbed itself. rather, I was wondering if there is an solution to modify (grind down, essenitally) the underside of the footbed without compromising its structural integrity. In the same vain, I guess i would trust myself more so than some of the local bootfitters.
For instance, I went to the shop to have my 6th toe stretch done. The shop was packed, the techs are all frantically running around. I tell someone what I need done and he takes my boots, gives me a slip and tells me to come back in two days. I really didn't think anything of it and just kind of walked out perplexed. They ended up stretching my boot without having looked at my foot. Granted, a 6th toe stretch is fairly routine, but I wasn't really pleased with how little measurement/analysis actually went into it.
Also, not sure why I am using footboard and footbed interchangeably but whatever, haha.
