* The ''NNN'' (New Nordic Norm, marketed by [[Rottefella]]), where a bar in the toe of the shoe is hooked into a catch in the binding. Also exists in the more rugged ''BC'' (Back Country) variant.

There have been several versions of NNN, with the latest incarnation known as the Nordic Integrated System ('''NIS'''), unveiled by [[Rossignol]], [[Madshus]], Rottefella, and [[Alpina Žiri|Alpina]] in January 2005;<ref>http://www.nordicskiracer.com/Equipment/2005/NIS/NIS.asp</ref> in 2007, [[Fischer]] abandoned SNS and switched to NIS, and [[Atomic Skis|Atomic]] abandoned NNN and switched to SNS. First NNN versions are not compatible with current NIS designs.
