Going from my first set of no-name cheap bindings to these was one of the best experiences I have ever had. These bindings have an aluminum frame and a polymer high-back. The responsiveness I felt the first time I rode with these bindings actually surpised me. The stiffness of the high-back allows effortless maneuverability and heel-toe movement, and the knew convertable toe strap allows you to use it as a traditional toe strap or utilize it as a cap strap. This means that the strap can be placed around the end of the toe of your boot, instead of on top of the top of the boot. By doing this, you can get your boot to the back of the binding easier and it allows for even more responsiveness. I believe Ride has replaced these bindings with their Movement Series recently, but the same technology is used and the Mig series bindings are still easy to find; allowing for a great deal on a phenomenal binding.
