You're going through exactly what I went through ~7 years ago with my CCMs, I almost hung them up because my feet would be numb and needing to deal with constant blisters. I tried different socks, footbeds, lacing methods and whatnot, and some days I would skate without pain, but then the next game it'd be worse. Got them punched twice by professionals, but because of the way my arch collapsed it was impossible to pin point exactly where I needed to get punched, if anything the first punch made it worse because afterwards the bottom of that punch would rub harder whenever I put weight on my feet as my arch collapsed.
In the end, I got custom Trues although my next skate purchase after that were non-custom TF9s as they had better moldability (they are comfy but not as comfy as my customs of course).
I really hope it goes better for you, but you may have to go custom if it doesn't work, or at least have a look at non-custom Trues and have them baked by a reputable store.
