Ultralight and minimalist by design, this binding style requires a ski boot with Tech-compatible heel and toe fittings. This binding style places a premium on stride efficiency and low weight, rather than adjustability.
An alpine-compatible AT binding offers an adjustable DIN, a burly construction, and accept a standard alpine ski boot without any special fittings. This binding can serve as a do-it-all backcountry and resort binding.
Heel risers or climbing wires can give you a boost under your heel for climbing steep hills and ski crampons can be used for more grip on icy terrain. Keep in mind, adjustable release settings and brakes aren't standard on some ultralight Tech bindings so consider your options carefully.
