Lol, i've always wondered this... Anyways, i just got some brand new k2 skis yesterday(my friend has the same pair) and his are wayyy more buttery!! They are so much more soft and flexible and poppy and all that fun stuff! We both have size 169 skis, different boots, and we are about the same height as each other. I tried to do a butter yesterday on the tips of my skis and managed to do it for a quick second before my bindings gave in and broke off my boots >.> (I'll adjust them i think)..
So, do you need to break in a pair of skis like you do boots?
