The Rottefella NNN BC Auto binding combines an intuitive and user-friendly design with a high degree of boot compatibility. When you’re done with a wind-blown tour, press your ski pole tip into the toe piece for an easy release. Notched grooves optimize power transmission so your skis feel like true extensions of your legs, and a wide platform enhances edge control. The NNN system hugs your boots while you lay fresh tracks, and lets them go when it’s time to spend some time by the fireplace.
