I desperately need a pair of custom insoles for my ski boots. Among other things, I have a particularly high arch. I've visited two bootfitters I'd heard decent things about and heard conflicting advice. The first (Elite Feet at Northstar) said that Superfeet Kork is the only way to go because the material continues to mold to your feet. The other (Sports ltd at Heavenly) said Instaprint is the way to go because it's a more modern and comfortable material.
But what about getting custom insoles made by a podiatrist? My podiatrist made custom insoles for my walking shoes, and they are great. He made a plaster mold of my feet, in a completely unweighted position, so there was no deformation of the shape of my foot caused by standing on them. My understanding is that with either Instaprint or Kork or just about any of the things that bootfitters do, there is at least some foot deformation that gets reflected in the insole, because the way they make the insoles is to press the material against your foot.
What are the pros and cons of having a podiatrist make custom insoles, versus having a bootfitter make them with Superfeet Kork, Instaprint, etc? What have your experiences been?
