The Absolute Guide to Buying Snow Ski Bindings

Ski bindings are an essential bit of kit for every skier. Without bindings you cannot use your skis. Whether your skis come with a track mounted system or drill mounted bindings our helpful guide below details every aspect of your binding and what you need to look out for when making your purchase.

When your ready you can  follow this link to Ski Bindings and apply the filters on the left hand side of the page see the Ski Bindings that are right for you.

What Is A Ski Binding?

Quite simply, a ski binding is the connection between you and your skis. Ski bindings are the system that transfers energy from your body into movement on the snow. Without a ski binding you cannot use your skis so they are essential. Some skis comes with pre chosen track mounted bindings. These have been specifically selected by the manufacturer to give optimal performance for the level of the ski. Other skis also come with drill mounted bindings or as a flat deck (ski only). These systems must be drilled into the surface of the ski and permanently attached by a professional and cannot be done at home. There are advantages and disadvantages of both types of mounting systems which are covered below.

All of our skis will clearly display whether they include bindings or come as 'Ski Only'. If they come as 'Ski Only' then check out our Optional Extras dropdown menu on each product to see compatible bindings that we personally recommend.

Binding Anatomy

There are two main parts to a standard alpine ski binding - the toe piece and the heel piece. These work together to ensure that the bindings perform precisely as they are designed to. AT (Alpine Touring) and Telemark bindings differ from the below Alpine binding however these types are less common. Check out the main parts of an alpine binding below.

Ski Bindings

Toe Piece

The toe piece is the front section of a ski binding which secures the front of your boot to your ski. The correct function of a toe piece is imperative during twisting falls. Twisting falls are one of the worst injuries a skier can sustain, often resulting in damaged ligaments in the knees. Because of this the toe piece has a horizontal release mechanism which allows the boot to slide out of the binding sideways but not vertically. Vertical release is left up to the heel piece. The toe piece consists of horizontal wings, an anti friction device (AFD) and DIN setting.

The horizontal wings work with an internal spring. This spring makes the wings grip your boot, preventing you from just falling out of the bindings. The spring has a specific retention range, or DIN setting, which can be adjusted and equates to the amount of pressure it takes to open the horizontal wings and remove the boot sideways from the binding, thus preventing injury. Ski binding toe pieces come in two basic designs (see the image below). Traditional toe pieces have the spring mounted parallel to the ski, in the direction of the bindings travel. This is a strong design which provides a large amount of elastic travel. Newer designs incorporate a spring mounted perpendicular to the ski, or at a 90 degree angle. This produces a compact toe piece which has a centre of gravity which is closer to the skier. These designs are becoming very popular with freestyle and backcountry skiers. Racers still prefer traditional toe pieces as they can be made to a high retention setting than newer compact toe pieces.

Heel Piece

The heel piece is the rear section of the binding that secures the rear of your boot to your ski. The correct function of a heel piece is important as it prevents damage to your knees during a forward fall. Forward falls can cause an over extension of the knee joint which can cause dislocations. Heel pieces have a vertical release mechanism which allows the boot to slide out on the binding vertically but not horizontally. Horizontal release is left up to the toe piece. The heel piece consists of a vertical arm, DIN setting and brake.

The vertical heel arm works with an internal spring. This spring makes the arm grip your boot to the skis, preventing you from just stepping out of them. The spring has a specific retention range, or DIN setting, which can be adjusted and and equates to the amount of pressure it takes to open the arm and remove the boot from the binding, thus preventing injury. Ski binding heel pieces come in two basic designs (see the image below). Traditional heel pieces have the spring mounted in the base section with the arm pivoting above it. This is a strong design which allows for very high DIN settings to be achieved making these styles popular with racers. Newer designs incorporate the spring into the arm itself. This produces a more compact heel piece which has a centre of gravity that is closer to the skier. These also have a high elastic travel which helps to reduce early releases. These designs are becoming very popular with freestyle and bacountry skiers.

Brake

The brake on a binding has one simple function - to make sure you don't lose your skis if they come off! When you are stepped into the bindings the brakes will raise and sit flush with the top of the ski. This keeps them away from the snow and out of the way. When you release from the ski the brakes pop up and the brake arms extend below the ski. These then catch the snow and lift the ski off of the snow. This prevents the ski from disappearing down the slope and getting lost. If you are choosing your own bindings for a pair of skis you need to make sure that you get bindings with the correct width brake. This is because a binding with a small brake won't open correctly and engage with the snow. Similarly a brake that is too wide won't sit flush on the top of the ski and may drag on the snow even when you are stepped into the binding.

Anti Friction Device

Ski bindings will have an Anti Friction Device (AFD) or gliding plate built into the toe piece. This AFD allows the boot to slide out of the binding more easily when the toe piece releases. There are two main types of Anti Friction Devices - static and moving. Static devices like product on the left of the image below are made of materials such as dense plastic or teflon. These are very low friction materials that allow the boot to slide over it without getting caught on anything. Moving devices like the product on the right of the image below have a plate that is held onto a track with a spring. This spring allows the plate to move and take the boot with it. When you release the plate helps 'carry' the boot out of the binding.

Methods Of Mounting

There are two methods of mounting bindings to skis - track mounted and drill mounted. There are Pros & Cons to each method.

Track Mounted

Track mounted skis are mounted onto a plate or track which is pre-drilled into the skis during construction. The bindings can then be slid onto the track and adjusted along the length of it to fit almost any boot size. There are two main benefits of a track mounted binding system. The first is piece of mind. With a track mounted system you know that the bindings have been specifically chosen by the manufacturer to work in conjuction with the skis. The track plate will have been designed to transfer the maximum amount of power to the skis without impacting the natural flex pattern of the ski. The second benefit is that track mounted bindings are easily adjustable. It allows you to easily change the mounting position of the bindings if you buy new ski boots, want to lend the skis to a friend of decide to sell the skis at a later date without having to have them professionally removed and re-mounted. Most track mounted systems can be adjusted without the use of tools. Some systems do require the use of tools but this is rarely more than a simple cross head or flat head screwdriver. Most piste and all mountain skis will come with track mounted bindings.

Track Mounted

Drill Mounted

Drill mounted bindings need to be professionally mounted because, as the name suggest, they are drilled and glued into the ski. This means that you can't do it at home yourself as there are special tools required. It would also void the product warranty. The benefit of drill mounted bindings is that it allows you to choose whichever bindings you want for your skis. This is particularly popular with freestyle and freeride skiers where riders are looking for specific performance properties. Drill mounted bindings often offer a greater level of control than track mounted bindings. They are also often lighter than track mounted bindings as they don't have the additional plate that is attached to the ski. Drill mounted bindings can be adjusted to different sized boots once mounted however the adjustment range is much smaller than on track mounted bindings. You can usually only adjust a couple of boot sizes up or down from their mounted position. Drill mounted bindings can be removed and re-mounted however this is a professional job and should not be done at home.

We match bindings which we believe offer the best performance for each ski. To see these optional extras just click on the optional extras dropdown on each ski listing. We can mount your bindings for you in our workshop at no extra cost (Terms & Conditions apply). Check out our FREE Ski Mounting Informationto find out more.

Types Of Ski Bindings

Alpine

Alpine ski bindings are made for downhill skiing from piste to powder to park and everything in between. Alpine ski bindings will come with all track mounted bindings and are the most popular type of drill mounted bindings. They will fit all alpine ski boots but will not fit Alpine Touring (AT) or Telemark boots (there are a few very specific models which will fit AT boots as well). Within the alpine binding category there are piste, powder, freestyle, freeride, sport and junior models but their designs are all very similar. Alpine ski bindings have a toe piece and heel piece with an adjustable DIN setting which allow the boots to be released from the binding during a fall. When choosing an alpine ski binding it is important to choose a binding that not only suits your skiing style, but also suits your ability, weight and height. Alpine ski bindings must be DIN certified. The DIN release allows the binding to detach from your boot during a fall to prevent injury.

Alpine Touring

AT or Alpine Touring bindings are designed for skiers who like to climb up as well as ski down. These bindings will look almost identical to most alpine ski bindings however the come mounted on a special frame which pivots vertically at the toe. This frees your heel and allows you to hike uphill using skins on your skis but then to lock the frame back onto the ski to descend the mountain. Most AT bindings will fit AT and Alpine ski boots thanks to adjustable toe ramps which allow the binding to accomodate the different shapes of each type of boot. Just like an alpine binding, AT bindings have releasable heel and toe pieces with adjustable DIN settings which allow you to safely eject from the bindings during a fall.

Backcountry

Backcountry bindings include Randoneé and Telemark bindings. These are very activity specific bindings are are designed for free heel movement for climbing. Randoneé bindings have a free heel movement for climbing but can be locked down in the heel for descents. These bindings can release at the toe and heel but often are not DIN certified. Telemark bindings have a free heel which cannot be locked down meaning you ski with a free heel on both ascents and descents. Telemark bindings also do not release during a fall.

DIN Settings

The safe operation of a ski binding is important to help prevent injury to the skier. The industry standard for binding release settings is known as Deutsches Institut für Normung, or DIN for short. DIN settings refer to a torque rating and are calculated by a combination of your boot size, height, weight, ability level and age as all of these factors affect the way the binding will release. Although it is possible for users to adjust their DIN settings themself it is not recommended that you do this. Leave this up to a specialist who knows the safe release range for you and your bindings.

DIN settings will be displayed on a ski binding with a range. DIN settings range from around 0.75 for small children to 18+ for powerful racers and big mountain skiers. The majority of skiers fall in the range of 4-10 with some people preferring to adjust their DIN settings up.
