Replying to Full tilts, foot beds and liners

I've got some older (2015 maybe?) full tilt dropkicks that never came with a foot bed. I was seeing the newer full tilts all have foot beds, was wondering if I could upgrade the liner and would that give me the ability to have a foot bed? And if so is it worth it? Was looking at the intuition pro wrap liners. But also see on the full tilt website they have their j-bar performance / pro liners so does any liner work or just the full tilt liners?

These boots have been treating me pretty good, though I feel lately my left foot has been falling asleep sometimes and it's probably not good. Generally though they are pretty harsh early season or if I haven't used them in a while, but after they're warmed up are as comfy as can be. Was thinking maybe getting new liners and going to see what a bootfitter can do could solve the problem. Or maybe I just get Dalbello Kryptons. Or just stop bitching. Idk.
