So i did some modifications to to the boots to give'm a little more flex that helped, i'm still going to get real snowboard boots though.
also, i'm use catek OS2s, and after riding for about in hour with just the boot mod, i switched my bindings from 0 lift front, 3 heel-rear (no cant), to 0 front, 6 heel lift (still no cant) this helped out alot, i think. I'm still fighting the boots, but i can feel the board, and ride it with alot more capablity than before. i can remember, but i think once my hand my i have touched the snow (if i did, i know their was no breaking at the waist)
So i'm deffenately not gonna give up on alpine, just cause of my boots. congrats, you guess got another keeper of the faith. =)
