yeah, shin bang is from having boots that dont fit you properly, if you can move your calf inside the cuff of your boots your going to get shinbang. this is usually a result of a combination of boots that were bought too big and sized improperly and a shitty packed out liner. if you really want to stop shing bang, go to a real ski store, and get a pair of boots fitted by someone who knows how to fit boots... if your getting shinbang already booster straps arent gonna do anything
