I got shin bang (lange bange) from my technica icon carbons last year, and they hurt..alot...all year long.
so here are some things you can do to your boot so you dont get it. cuz it practically ruins weeks of your skiing and you feel it all winter long
first of all, buy a MasterFitU custom foam tongue. it fits inbetween ur shin and normal tongue.. this almost eliminated the problem.
buy a BOOSTER strap. it replaces your old strap with one that is flexible. so just in case you happen to flex too far, it will go with you
if anyone else has suggestions to make ur boot more comfortable or to prevent lange bang, please share
