If you mean my statements above, ramp angle redistributes weight-bearing to the front of the foot somewhat, and also raises the COM point vertically. This decreases stability, and makes driving forward very easy. But for every action is a reaction, and all that unstable forward driving will sling-shot backwards coming out of a turn and throw you into the backseat (unless you prevent this from happening).
If I had upright boots with less ramp, it wouldn't be as easy to throw myself forward... thus it would be harder for the setup to equally throw me backwards.
Of course, my theory was formed in part from reading the prejudicial views against my boot geometry in Ray's posts, all over this site, and elsewhere saying that "modern skis" don't need old-school boots
(and I don't mean "my" boots specifically, but forward-leaning race boots in general).
But surely there is a reason that race boots still are stiff with alot of forward lean?
