Ok, before you dismiss this question as a duh!, let me explain.
I am a new skier, started skiing this year. I have hit the slopes 6-7 times this season and plan to go once a week till the end of the season. I am making good observable progress and at this point I can tackle the green and easy blue slopes without any difficulty but I am still hesitant on the tougher blues. So, to avoid the rental queues and save money I purchased a used pair of skis and boots off Craigslist!
Before this I rented 27.5 size boots at the resorts and I had no complaints about foot pain. Now I bought these size 28 Nordica Easy Move boots thinking that a 0.5 size should not matter much. Turns out that my arches (or insoles?) were hurting quite a bit after doing long tough runs. I had to wait for the pain to subside before moving on again. I did this for the whole day thinking that my new boots were duds. However, after getting back home, the previous owner of the boots contacted me saying that he left his orthopaedic insoles in the boots and wants them back! So now I am hoping that the problem was due to the wrong insoles and not just a bigger boot.
I did a shell fit test and found that my foot ends around 1.5 inches from the back of the shell. However, with socks on (and without any footbed), I can't move my foot inside the liner (or so I think). The boots are probably 3-4 years old (atleast).
What should be my next course of action?
Should I get some generic insoles like Superfeet and add them to the boots? (When I bought running shoes, the seller told me after some analysis that my feet had normal pronation, regular arch. I don't know if that helps here.)
Should I just return/resell these boots and buy new ones from a good boot fitter? Since I am a new skiier, I dont want to buy expensive beginner boots and then get stuck with them as my skill level grows.
