NNN-BC (New Nordic Norm Backcountry) bindings use a single bar at the toe of the boot that pivots in the binding, similar to classic NNN but with a wider, stronger interface. They offer excellent touring efficiency and are the most popular choice. 3-pin (75mm) bindings use three pins that insert into holes in the boot sole duckbill, providing a more rigid boot-to-ski connection that many telemark skiers prefer for better turn control. 3-pin is heavier and less efficient for touring but offers superior downhill performance. The systems are not interchangeable—you must match boots to bindings.
