From what I've read on the forum, at near 200 lbs and 6' plus, I should be able to crush them like bugs and break them in two the first time I tried to flex on them. But here is the thing, I don't really find them soft (they are a bit wide around foot but that's another story). If I buckle them all at 1st notch, yeah my legs float around in them, however with my usual routine of powerstrap between tongue and shell and tighten the two upper buckles two or three notches after a few runs, they seem to work fine. I thought I am an intermediate skier, since even beginners my size were recommended to get 80/90 flex boots they should be way too soft for me right?
But maybe I'm way overestimating my skills, so we'll take it out of the equation. Buckling them to my usual position, I can stand on two toe pieces only, and put all my weight on my shins, the shell still flexes just a little. It's only when I put all (okay most, need hands on wall to keep from toppling over) my weight on one shin, the shell flexes a bit more (I put my hand between the 1st and 4th buckle and feel the distance shortens). The shell seems pretty stiff and can support my weight well, despite the low flex rating.
So how does this work? I'm quite confused by this to be honest.
