How to Choose Ski Bindings
Scoring a pair of older but pristine skis at ski swap can give you serious shopper’s high and make your season, but shopping for ski bindings gets a little trickier.
There’s no pretty topsheet, stiffness to test, or sidecut to eye; there are only mysterious inner workings. But don’t be intimidated; essentially bindings attach your boots to your skis. For most types, this job also entails efficient transfer of energy from boot to ski and safe release when you fall, but it’s not rocket science. There are three main types of bindings, and here is how to choose which ones are right for you.

There are three main types: alpine, alpine touring (AT), and telemark for alpine, backcountry, and telemark skiers, respectively. Nowadays there are bindings with AT and alpine interchangeability for those who have both boot types and want that adaptable convenience. But for general clarity alpine and AT are discrete categories, and telemark bindings only work with telemark boots.
Alpine bindings are made for alpine boots for in-resort downhill skiing. The different models depend on ski style and Deutsche Industrie Norm, known as DIN, release setting. There are different categories that include freeride, race, freestyle, sport, and junior. Choose the binding in your style and category that has the appropriate DIN range. Your DIN setting is determined by your skill level (Type 1, 2, or 3) and weight (some charts also incorporate age, height, and boot sole length). Beyond the expert level, DIN setting is even less scientific and depends heavily on personal comfort levels. For example, there are many featherweight but aggressive racers or freeskiers who like a high DIN.
Alpine bindings are made to release during a fall, based on the DIN number, to reduce risk of injury. They consist of a toe piece, which includes an anti-friction device (AFD), and a heel piece with a ski brake. Most bindings feature wide-angle, multi-directional, pivoting release for the wicked backward twisting fall. They also feature height adjustment and varying profiles and platform widths to accommodate today’s fat skis. Brakes come in different sizes, but usually are easy to swap out to fit different skis. When choosing a brake width, select an option that is equal to your ski’s waist width, or up to 15mm wider.
Knowing your general DIN setting is important when selecting a new pair of bindings. To find it, simply take a look at the small window on both the toe and heel of your current bindings. You will see a small mark or line that lines up with a number—that number is your DIN (The heel and toe should both be set to the same DIN). You ideally want your DIN to fall somewhere in the middle of the binding’s range, not at the high or low limit. Reference each binding’s tech specs to view its DIN range.
Frame AT Bindings
If getting away from the crowds and making first tracks is your thing, then AT is a logical option. These bindings generally fit both AT boots and alpine boots and provide a safe touring platform for backcountry skiing. A base plate and frame link the toe and heel, and the binding pivots for free-heel climbing in hike mode. On the descent, the binding locks down for alpine-like performance. In recent years, AT setups have made big advances in weight reduction, durability, and performance. You’ve probably even seen AT gear ripping around at the resorts.
These are releasable bindings and operate like alpine bindings, with multi-directional, multi-pivot release, and an adjustable DIN range. You choose them in a similar way, taking into account preference and comfortable DIN accommodation. AT bindings come with different brake widths, but, again, these can be easily changed.
Tech AT Bindings
Tech AT bindings are used by serious ski tourers. They don’t typically have a full ISO/DIN-certified release rating, and some lack brakes to save weight while skiing uphill. Furthermore these bindings require the use of alpine touring-specific boots that have special steel fittings to create a solid boot-to-binding interface.
As they say, “Free the heel, fall on your face” … or something like that. Don’t believe it—telemark skiing is an old and beautiful free-heel ski style that can take you into the backcountry but also perform inbounds. The bindings only work with telemark (or tele) boots, but you won’t inadvertently come home with tele bindings, since they look very different from alpine or AT. The tele binding has a fixed toe piece that can come with or without a cable and heel throw. A simple heel plate comes with it and can come with a climbing bar for easy hiking. If your boot has a three-pin toe, you can go without the cable and opt for a three-pin toe plate for secure attachment. These cable-free bindings provide the least support and are best for touring in soft snow.
Like AT bindings, tele bindings have also made great strides and come as releasable (but with a free heel there is no DIN setting) with ski brakes and/or with varying and adjustable cable stiffness for freeride tele skiers. There’s not as much variation with tele bindings as there is with alpine or AT, so the choice is largely based on style preference (e.g., releasable vs. non-releasable and cable stiffness).
Mounting, Maintenance, Etc.
Mounting your ski bindings means drilling into your skis and should always be done by a certified technician. It requires the bindings, skis, and boots, plus your personal ski info to determine your proper DIN setting if mounting alpine or AT. There are manufacturer-recommended mounting positions, but some skiers prefer a position that’s more forward on the ski or further back. If you’re unsure, talk it over with your shop tech; it’s mostly a personal preference. If you want a riser plate (a raised platform under the binding) or different brakes, bring those in, too.
Ski bindings are maintenance-free, but should be adjusted by a certified ski tech each year. You can wipe or hose them down, but cleaning them with soap or solvent is not advised.
Ski bindings should provide peace of mind with an appropriately secure hold while reducing risk of injury upon a release. If you still have questions about what ski binding is right for you, reach out to one of our Gearheads, who are here to help.
