If you’re using a lever punch, blend out the edges of the punch as it follow the die very aggressively and can leave hard edges, especially if you have a linkage driven punch that really follows through at the end of the motion. As Greg said, it takes a skilled bootfitter, but not one more skilled than someone who can punch any other boot and has punched at least one grilamid boot before.
Ps. I heat gunned the sides of my boot while they were on my feet and it very much heat molded the shells.
