Young_IMPCI feel the same. My boots fit without issue- no pain, no heel lift, toes at the front, and the shins at the tongue. I did crack the shell though, so we’ll have to see if I can warranty a replacement. While you would get better performance out of a custom fit, I think it’s then a question of whether it’s worth it to you.
inb4 Tom and OneNerdy come out of the woodwork to chastise me for not having a custom insert
How could you ski in such an awful fitting pair of boots especially at this time in the world!!!
So its an interesting topic. If your boots don't hurt do you need anything else? Well it depends. Technically no you don't, if you can comfortably wear your boots and they don't hold you back, go for it. Number one is getting out and skiing (when we all can again) and having a rad time.
But could your boots fit and perform better? Probably yes. Does this mean you have to have it done, no of course not, but if you have the option and the money it will never hurt to have it done. But be warned once you do get boots fitted to the very highest level its really hard to go back from that and just use stock boots again.
So overall do you need custom work? Possibly not.
Should you get custom work done? Maybe
Should you enjoy skiing above all else? Yes!
