AT bindings, or Alpine Touring bindings, are specialized ski bindings designed for backcountry skiing. They allow skiers to walk uphill by releasing the heel, enabling a natural stride. When descending, the heel locks down for stability and control, similar to traditional alpine bindings. These bindings are essential for those who venture into untracked terrain, as they provide versatility for both climbing and skiing. AT bindings come in various styles, catering to different skill levels and preferences, making them a popular choice among backcountry enthusiasts and ski mountaineers.
