ALPINE & ALPINE TOURING BINDINGS
Ski bindings are a crucial component of your ski equipment. They connect the ski boot to the ski, allowing you to control your movements and transfer energy to the ski for steering and stability.
Ski Binding Size Chart: binding size, or brake width, is determined by ski waist* width. Brake width should be equal to, or a maximum 15mm wider than, the ski waist width.
Binding Size (mm) | 80 | 90 | 100 | 110 | 120 | 130 |
Ski Waist Width (mm) | 65 - 80 | 75 - 90 | 85 - 100 | 95 - 110 | 105 - 120 | 115 - 130 |
Types of Downhill Skiing Bindings:
Alpine Bindings: are the most common type of downhill ski bindings. They’re designed for use with alpine (downhill) ski boots and alpine skis and come in various models, including standard, demo, and integrated systems.
Alpine Touring (AT) Bindings: aka randonnée or backcountry bindings, are designed to use with alpine touring or backcountry ski boots. You can switch between alpine skiing and touring modes. AT bindings often have a walk mode to make going uphill easier.
Components of Downhill Skiing Bindings:
Toe Piece: The toe piece of the binding secures the front of the ski boot to the ski. It typically has an adjustable release setting that determines how easily the boot will release in the event of a fall.
Heel Piece: The heel piece secures the back of the ski boot to the ski. It also has an adjustable release setting for the boot.
Brakes: Most alpine bindings have integrated brakes that prevent the ski from sliding away when the boot is released. The brakes deploy automatically when the boot is not engaged in the binding.
DIN Setting: The DIN (Deutsches Institut für Normung) setting is a numerical value that determines the release force of the binding. It is adjusted according to the skier's weight, ability level, and skiing style. A higher DIN setting indicates a greater release force.
Ski Compatibility: Bindings need to be compatible with the ski's mounting system, including the binding mount pattern and mounting screws. Bindings must match the ski's specifications.
Choosing Downhill Ski Bindings:
Ski Ability Level: Bindings are available in various performance levels to match skiers' abilities. Beginners may prefer bindings with lower release settings, while advanced skiers might opt for higher-performance bindings.
Ski Boot Compatibility: Ensure that the bindings are compatible with your ski boots. Alpine bindings are designed for alpine boots, while AT bindings are for touring boots.
Ski Type: Choose bindings that are compatible with your type of skis (e.g., alpine or touring skis).
Release Setting: Have your DIN release setting adjusted by a certified tech based on your weight, age, skiing ability, and preferences.
Brake Width: Ensure that the brake width of the bindings matches the width of your skis, and is wide enough to stop the ski from sliding.
Binding System: Some skis come with integrated binding systems, while others require separate bindings. Make sure the bindings match the ski's system if you're not using an integrated setup.
Binding Release Settings: Have these regularly checked and adjusted as needed to match ski conditions and your skill level. Properly functioning bindings are essential for your safety on the slopes.
Alpine Bindings:
Standard
Design: standard alpine ski bindings are designed for traditional alpine skiing. They consist of two separate bindings—one for each ski—that attach to the ski's mounting plate or binding interface.
Compatibility: these bindings are compatible with a wide range of skis as long as the ski has the appropriate binding mount pattern. Standard bindings are often the choice for experienced skiers who have a specific preference for bindings or who want more flexibility in choosing skis and bindings separately.
Adjustability: they have adjustable settings for both the toe and heel pieces. This allows for customization based on your boot size, weight, and skiing style. DIN (Deutsches Institut für Normung) settings determine the release force required for the binding to release the boot during a fall.
Demo (demonstration)
Design: are for use in ski rental shops, for ski testing, or for situations where the same pair of skis needs to accommodate multiple skiers with different boot sizes.
Compatibility: demo bindings are adjustable in terms of both boot size and ski boot sole length. They are designed to be versatile and fit a range of boot sizes. This adjustability makes them suitable for rental fleets and ski demo events.
Release Settings: as with standard bindings, demo bindings have adjustable DIN settings for different skier abilities and preferences.
Integrated
Designed: as a complete package with the ski, binding, and often a specific ski boot model. The binding is integrated into the ski's design, with a predefined mount position and interface. These systems are commonly found on performance or racing skis.
Compatibility: only compatible with skis designed for that specific system. The ski, binding, and boot must all be part of the same integrated system for proper function.
Performance: engineered to optimize the ski's performance, including power transmission, edge control, and responsiveness. They're popular among advanced and expert skiers who prioritize performance.
Adjustability: offering limited adjustability in terms of boot size, they often have fixed mount points, making them less versatile for customizing your setup.
When choosing between standard, demo, or integrated alpine ski bindings, consider your ability, preferences, and the specific skis and boots you plan to use. Standard bindings offer the most flexibility, demo bindings are good in rental situations, and integrated systems are better for advanced skiers who want a high-performance, matched setup.
Regardless of the type of bindings, have them properly adjusted by a ski tech to ensure they release appropriately for your safety.
Walk Mode:
Release the Heel: in walk mode, AT bindings allow you to release the heel of your ski boot from the binding. This allows for a more natural, efficient walking stride and flexibility in your ankle.
Free Pivot: the binding's pivot mechanism typically allows for a free and easy pivot at the toe piece so you can lift your heel while the front of the boot stays attached to the binding. This is essential for climbing uphill or navigating flat terrain.
Increased Range of Motion: walk mode provides a greater range of motion in the ankle and lower leg, making it easier to take steps and ascend slopes.
Comfort and Efficiency: by allowing your heel to lift and providing a more flexible walking motion, walk mode enhances your comfort and energy efficiency during the uphill or flat sections of your tour.
The Importance of Walk Mode:
Uphill Climbing: When ascending uphill slopes, walk mode is crucial for conserving energy and making it easier to lift your feet. It allows you to walk more naturally, similar to regular hiking.
Flats and Rolling Terrain: On flat or gently rolling terrain, walk mode ensures that you can move efficiently without your skis dragging or impeding your progress.
Boot Compatibility: AT bindings are designed to work with compatible ski boots that have a walk mode feature. The binding's toe and heel pieces must align with the boot's walk mode mechanisms to function correctly.
Safety: Walk mode allows you to release your heel from the binding, which can enhance safety by reducing the risk of injury during falls or awkward movements.
Transitioning: The ability to switch between ski mode and walk mode quickly and easily is essential for transitioning between skiing downhill and touring uphill.
Familiarize yourself with the specific walk mode operation of your AT bindings, as it may vary depending on the brand and model (follow the manufacturer's instructions). Practice using your AT bindings in different modes to ensure you are comfortable with the transition and operation before heading into the backcountry.
