NNN (New Nordic Norm by Rottefella) and Prolink (by Salomon) share the same sole profile and are functionally cross-compatible—you can use NNN boots in Prolink bindings and vice versa. SNS (Salomon Nordic System) is an older Salomon standard with a different sole interface that is NOT compatible with NNN/Prolink. SNS is being phased out, so new purchasers should choose NNN/Prolink for the widest boot selection. Turnamic (Fischer/Rossignol) uses the NNN sole standard and is fully compatible with NNN boots.
