New Nordic Norm bindings, also called NNN bindings, are a type of ski binding. Ski bindings are used to connect skiers with their skis, and are designed with a locking mechanism to prevent separation. Ski bindings have been in use since skiing was developed, and have evolved a long way from strips of animal hide and bark.

There are a wide variety of ski bindings on the market, depending on what type of skis are involved and their intended use. NNN bindings are easy to use and standardized across much of the ski market. For cross country skiing, NNN bindings are an excellent choice.

NNN bindings use a short metal rod in the toe of the boot which connects with a corresponding clip-in binding on the ski. In addition to the toe binding, NNN bindings also include a series of matching ridges on the boots and ski for greater grip and control. Several skiing disciplines take advantage of NNN bindings because they are easy to use and provide great flexibility for the skier. NNN bindings include a safety release so that if a skier falls, he or she will not become entangled with the skis.

NNN bindings allow freedom of movement for the heel, which is a crucial part of cross country skiing and telemark skiing. The skier can lift his or her heel entirely out of the binding but still be firmly connected at the toe. When solid lateral traction is needed, the skier can place his or her heel flat on the ski and connect with the ridged features of the binding.

A number of manufacturers make NNN bindings. One of the most popular is by Rottefella, a Norwegian ski equipment company. Rottefella bindings are used by a number of ski professionals because of their solid construction, durability, and ease of use. The company also makes traditional three pin ski bindings for Telemark skiing.

Another company, Salomon, makes a binding system similar to NNN bindings. The Salomon Nordic System (SNS) bindings are also constructed with a binding rod and ridges. However, the layout of the SNS binding system is slightly different. Therefore, boots and ski bindings designed for SNS use are not compatible with NNN bindings.

Because some manufacturers make slightly different versions of NNN bindings, skiers should always check for binding compatibility when purchasing new equipment. Some manufacturers are cross compatible with each other. Others make slightly different designs which will not work properly together. If you are uncertain about binding compatibility, consult the staff at a ski shop or the manufacturer directly.
