Ok. I've found a pick of what looks like the entire line-up, but no close-ups or nothing in depth. If anyone cares, the F3 is in the middle column, 2nd from the top. And the F4 is in the upper left corner. Anyone have experience with these boots? I'm getting contradictory info regarding flex. Salomon says the F4 is an 8, but some say it's way softer. I'm wondering is this the case for the F3 as well?
