I demoed the NOW bindings for a weekend at the end of the last season at the recommendation of a local shop tech. I was skeptical, but figured I'd give it a try.
Other than feeling more of the flex of the board, I really didn't notice much difference between traditional bindings and the NOW bindings, especially in turn initiation. That is not to say it isn't there. What I did notice that for the first time all season I wasn't suffering from foot pain and my legs were not tired at the end of the day. I had spent all season trying to find the right boot/binding/insole combination to make the foot cramps tolerable. My boots (size 10 reduced footprint in several brands) fit the heel cup perfectly. Surprisingly I liked how few adjustments the bindings have. By the end of the weekend, I seriously considered telling the shop that my board was stolen, because I didn't want to return a part of the only boot/binding/insole that allowed me to ride without foot pain.
I picked up my pair for this season from the local shop yesterday. Build quality is nice. The buckles seem to be much improved from the demo model.
