It's hard to find powerful bindings that take a simplistic design approach. That's why the K2 Program is the perfect option for the advanced to expert rider who's looking for a more responsive option but doesn't want to deal with any added features. The power of this binding is provided through a stiff highback and that's it. The shape of the highback wraps the back of your boot to lock your heel in place, while the lightweight straps have a bit of flex to provide forgiveness on the top of your foot. We've tested this binding on a number of different all-mountain boards and it always provides a solid performance. The K2 Edition is a slightly softer option with more cushion in the straps, a great option for more casual riders.
