ski binding is a device that connects ski boots to skis. Generally, it holds the boot firmly to allow skiers to maneuver the skis. However, if a certain power limit is exceeded, it releases the boot to minimize the injury of the skier, as in the case of a fall or collision. There are different types of bindings for different types of skis.

Alpine
The modern alpine ski boot fixes the boot at the ends of the feet and heels.
In some bindings, to reduce injury, the boot can be detached if there is a fall. Booting is released by binding if a certain amount of torque is applied, usually made by the weight of a falling skier. The required torque is adjusted, according to the weight, foot size, and ski style. The snow brakes prevent the ski move when not attached to the boot.
Also known as randonee, the alpine touring binding allows the heel to be cut into skiing while skiing downhill, but allows it to be released while climbing.
Alpine touring
The binding of the alpine tour allows skiers to have free ski heel boots and ski boot tips in binding while using the Nordic skiing technique for skiing tours, and has heels and toes on skis while using alpine skiing techniques to descend the mountain. Most tour blades are designed for ski boots that fall under one of two ISO specifications:
- ISO 5355: 2005, for traditional alpine boots. In this variation, the pivot is located in front of the binding.
- ISO 9523: 2008, to boot where the pivot is formed on the boot/binding interface.
These two settings are incompatible: in the first, the boot does not have a socket to use compatible ISO 9523 bindings, while the boot-toe and heel-part heels are then not compatible with ISO 5355 bindings.

Cable binding
Cable binding was widely used until the mid-20th century. It has a toe section of an anchored boot, and an adjustable cable around the heel secures the boot. While the binding design varies, before 2007 virtually all of the dedicated Telemark models have been designed to fit the shoes with 75mm Nordic Norm "duckbill" toes.
Rottefella (NN, Norm Nordic)
Rottefella binding was developed in 1927 by Bror With. His name means "mousetrap" in Norway. It is also known as 75 mm, Norm Nordic, or 3-pin. After victory at the 1928 Winter Olympics in St. Louis. Moritz, binding remains the standard for cross-country skiing over the next 60 years. They are no longer as popular as they are but are still sold. The bond has three small pins attached from the binding. The shoe end has three holes where the pin is inserted. Booting is then clamped by a guarantee. The binding is asymmetrical, having left and right foot orientation. Before Nordic Norm, cross country binding skiing has as many as four pins.
NNN (New Nordic Norm) & amp; NIS (Nordic Integrated System)
Rottefella's NNN (New Nordic Norm) has a bar at the boot end that connects to the corresponding latch in binding. There are several versions of NNN, and the first NNN version is not compatible with the current design. Stronger BC (Back Country) versions also exist.
The NIS (Nordic Integrated System), introduced in 2005 by Rossignol, Madshus, Rottefella, and Alpina, is fully compatible with NNN boots and bindings, but is a different way of attaching bindings to skis. It features an integrated binder plate at the top of the ski binding that bindings, enabling adjustments in the field. Ski NIS allows the installation of non-NIS bindings. In 2007, Fischer left the SNS and completely switched to NIS.
SNS_.28Salomon_Nordic_System.29 "> SNS (Salomon Nordic System)
SNS (Salomon Nordic System) looks very much like NNN, except it has one big ridge and a narrower bar. There are three variants:
- SNS Profile: One metal bar at the boot end.
- SNS Pilot: Two metal bars at boot.
- SNS X-Adventure: Stronger designs are used for skiing in other countries (also referred to as SNS-BC).
Pilot boots can be used with Profile binding but Profile shoes can not be used with Pilot bindings. The original pilot boots have a 10 mm front pin from the front of the boot (RS10), while the newer Pilot boots have a 17 mm front pin from the front of the boot (RS17). SNS is marketed by Amer Sports under their Salomon and Atom brands.
The predecessor is simply called Salomon Nordic System (SNS):
- SNS: "U-shaped" metal bar protrudes from front of boot
Prolink (system compatible with Salomon NNN)
The NNN Rotefella system was adopted by Fischer and their various brands, making the SNS decline used in North America. Responding to the need for NNN compatibility, by 2016 Salomon introduced the Prolink system, although Salomon claims that SNS will continue to be produced and available. Prolink binding is somewhat lighter than NNN and is directly attached to skis, compared to NIS plated NIS plates used by NNN. Salomon claims their new system delivers superior "snow flavor" compared to NNN or even their own SNS system paired with thick soled boots.
In 2007, Rottefella introduced the New Norm Telemark binding. The purpose of this system is to provide freeheel telemark ski binding featuring lateral release, lateral stiffness enhancement, melodious performance, and free rotation toiv functionality. The boots are not like other telephoto shoes because they do not have 75 mm square feet and require lips under the boot arch for binding to fit. Scarpa sells boot versions that are compatible with NTN Tele and Dynafit bindings. The current Rottefella (2015) offers two binding models, Freeride for lift-assisted skis and Freedom for the tourer. Both models have a free pivot and one standard boot, NTN. Different spring cartridges can be used to match binding to the skier's weight and ski style.

History
In the early days of skiing, the binding was similar to that used in snow shoes: leather straps tied at the end of boots.
