Best bindings money can buy, Period.
I own these and a pair of the even more astronomically priced C60s and these are easily the better of the two. I agree with the other reviewer who doesnt agree with their "stiff" rating. I definately wouldnt call them flexy but I certainly dont condiser them super stiff, I'd call them about perfect in my opinion but, then again, I'm 6' 225 lbs and ride a '64 wide custom x that most people call huge.. so I guess these might be very stiff for someone 50 lbs lighter, on a smaller board.
For all the people complaining about the price... that's Burton, either you like their gear and see its worth or its too pricey but you most definately get what you pay for. Not just in terms of the product itself but, should the need arise, their support is second to none.
These binds are light weight, look great, are about as secure as welding your foot to the board (sorry to the reviewer whose foot mysteriously slipped out but I'd chalk that up to user error), have just the right amount of flex and will make you feel like you can take on any terrain with confidence.
