COMPATIBILITY - The Rottefella NNN-BC Auto fits all Rottefella NNN-BC soles but DOES NOT accept NNN Touring soles so look for the NNN-BC logo on your boot soles if you are uncertain
STEP-IN DESIGN - The step-in mechanism provides an audible indication when securely fastened and can be easily disengaged using the tip of your ski pole; the NNN system holds your boots snugly while you carve out fresh trails, and allows for quick release when you're ready to relax by the fire.
STABILITY & STRENGTH - NNN-BC Auto bindings are wider for more stability and stronger than regular NNN bindings to withstand the rigors of off trail skiing
STEERING RIDGES - The integrated "Steering ridges" ensure maximum ski control and the flat heel plate provides stability in off-trail situations
EDGE CONTROL - Notched grooves optimize power transmission so your skis feel like true extensions of your legs, and a wide platform enhances edge control
