What is the difference between NIS and IFP binding systems?

NIS (Nordic Integrated System) by Rottefella and IFP (Integrated Fixation Plate) by Salomon are the two main Nordic binding platforms. Both allow tool-free binding position adjustment but are not cross-compatible. NIS uses a plate bonded to the ski with bindings that slide and click into place. IFP uses a similar integrated plate system. Your choice depends on which boot/binding brand ecosystem you prefer—Rottefella bindings (NIS) or Salomon bindings (IFP). Both perform excellently.
