Replying to When to get new boots?

Currently my boots fit pretty well but they have packed out a ton from skiing at the resort 3-5 days a week and skiing in my yard usually about a 1-2 days a week. I’m close to 50 or 60 days now and their starting to not feel as snug and tight as I like them, even when it’s super fuckin cold. I’ve got both my top buckles all the way buckled and the bottoms on 3/4 over. Their K2 BFC 120s, I needed the wide boot to fit my pancake of a foot, and I realize that a k2 120 is nothing like a Lange 120. Would booster straps help? Or should I just buy new liners after this szn is over?
