The Salomon Nordic System (SNS) cross-country ski binding was the first integrated boot-binding system for cross-country skis, followed by the New Nordic Norm. The first generation (SNS) employed a looped bar protruding from the sole of the ski boot. Subsequent generations engage a bar recessed in the toe of the boot and incorporate a single, thick ridge along the binding plate. The variants included:<ref name=":1">{{Cite book |last=Hindman |first=Steve |url=https://books.google.com/books?id=n2ejJvg-snUC&dq=SNS+bindings&pg=PA70 |title=Cross-Country Skiing: Building Skills for Fun and Fitness |date=2005-09-14 |publisher=The Mountaineers Books |isbn=978-1-59485-278-7 |pages=69–70 |language=en}}</ref>
* SNS: Attaches to a U-shaped metal bar protruding from the front of the boot
* SNS Profil: Attaches to a recessed metal bar in the toe of the boot.
* SNS Pilot: Adds a recess for a second metal bar on the boot to enhance side-to-side control.
* SNS X-Adventure: Stronger design used for back-country skiing (also referred to as SNS{{endash}}BC).
Pilot boots can be used with Profil bindings (Equipe models and similar, with a groove for the second Pilot axle), but Profil boots cannot be used with Pilot bindings due to the wider guide ridge of the latter.
