The Shogun boot comes out the new X3 race series (not the older Falcon mold), which means the boot has a raised toe height of 4mm. Because Salomon raised the toe, the boot has less forward lean to maintain the same foot to leg angle. The actual 18 degree (not exactly sure what it is) is the same but the positioning of angle has changed. Imagine that you have this < but just tilt the whole thing counter-clockwise a little. Does that make sense?
So, even with "only" a 100 flex index, the boot still rips turns because of the elevated toe design. Instead of having to flex the boot, you just put more pressure on your toes and it makes the ski dance. I skied it last year and was super impressed.
