I picked up a pair of Salomon Mission alu boots on clearance at Sports Authority (only place in town I found with boots). The flex is not written anywhere. The sign listed them as 2013 boots but they do not show up on Salomon's USA website. They do show up on Salomon for some European countries.
I've read the articles here on fitting and feel this is as good as I'll get until I can go to a boot fitter. For the Mission GTI alu, I found a place saying all mountain for beginner/intermediate. For the Mission alu (photos matched) the site said "Sport" and I'm unsure what that means. My question is this boot acceptable for an advanced beginner to intermediate skier? Same overseas Salomon website also said flex was 70 but it is not written on boot or box.
