I have Atomic Zone 7.45 317mm with original 27.0 Atomic liner
I would like to improve warmth and comfort.
I have size 9 feet with a high arch.
Could you recommend new replacement liner options.
The boots are about 13-14 years old. You'd be doing yourself a favor by going to a knowledgeable bootfitter and just getting new ones. New liners will cost at least $200 and it's not terribly straight forward determining which one will work best.
