In the many reviews of these boots (also called Crossmax 10.0), they stress the boot's tendency to FIT a number of feet. That's been my experience -- they fit great. I now ski without thinking about how much my #(@#&# feet hurt. I spent a number of years working with Surefoot to get my Lange X09's to fit. They never did, and I came to believe -- after working with an expert bootfitter -- that the Langes weren't a good match for my feet and Surefoot REALLY screwed up the custom footbed/orthotic. I skied in constant pain until switching boots and bootfitters. They are quite STIFF -- about 10% softer than the Salomon Course race boot. Stiff enough so you can get back to center fast, without being so stiff that your shins get too hammered. And they're relatively UPRIGHT, what Harald Harb and other cutting edge technique and gear theorists call "LATERAL" boots. Contrary to popular opinion, racers ski in boots that are relatively upright, so when they crank their knees over to turn, the ski goes on edge without rotary movements. Get a boot with too much forward lean or heel lift (ramp angle) and your skis will tend to twist (skid) when you move your knees into turns. I love these boots!
