NNN (New Nordic Norm) and Prolink are the two current standard Nordic binding systems. NNN is used by Rottefella, Madshus, and others. Prolink is used by Salomon and Atomic. Both systems are functionally similar and can be used with each other's boots using adapter plates. SNS is an older Salomon system that is being phased out—avoid it for new purchases as boot and binding options are shrinking. All three systems allow the heel to lift freely for the classic stride. The key is matching your binding system to your boot choice.
