This boot is made for the young generation of racers. It has a 60 flex so isn't extremely stiff but does have some resistance so you won't overpower it. It is a fully customizable shell and liner so that it can be tuned to your racing fit you need! The liner it'self is a comfort fit liner, so you are comfortable and stable.
Overall this boot is for a younger racer who wants to ski aggressively but not an aggressive as a master will be. It's also a boot for someone who wants to only ski really hard and not ver take a relax run down.
