Hey guys just because it is in the same mold does not mean it is the same boot. Porsche and VW share the same frame, does that mean that my VW will do 150 with out hitting the gas? The 1080 boot is much like the XWave 7 when it comes to flex. As far as the better boot between the 9 and 10, I like the 9 because it does have a little nicer flex than the 10 for freeriding. The 10 is great if you want to go balls out every run, but the 9 which has a flex of 100 (by Salomon standards) is the more all around boot. The 1080 boot does not ski anything like the XWave 9 which a has a superior liner and stiffer flex.
