Replying to Shin bang full titl boot help.

I've been having shin bang issues with my full tilt dropkick pros for a while, getting back into ski season has brought back my shin bang , I felt great in my boots in the beginning few days of the season, but now it hurts to even try to lean forward in my boots, Im tall with skinny lower legs and not that flexible of a heel and am wondering why my shins keep hurting, If anyone has ideas of why this is happening help a brother out , My middle buckle broke on my boot trying to get it tight and I have booster straps on them to crank down on the top. Will a new buckle, or a new foot bed, or softer tounge, or shin expanders work, also will be trying to rest them as much as possible if anyone has ideas with that let me know.
