it performs really well. the ability to move the stance forward and back is super nice. they ski like normal jesters, but a little heavier, nothing that you would actually notice while skiing. the adjustment can be made very very quickly. the screw on the bottom of the toe piece is what controls the position of the boot.
they are cool looking and the ability to change the position is really sick
they retail for 450ish and that is a little expensive for a binding, but if you are using a one ski quiver then its worth it
