Originally a breakthrough in the binding market, the Marker King Pin 10 AT binding was the first to combine a touring-specific tech toe with an alpine-style heel. Now a few years into production, Marker has tweaked its design a little while remaining at the forefront of what is a new direction of bindings. As more and more skiers push themselves inside and outside the resort, they continue to turn to the Kingpin as a trusty and versatile tool for getting where they need to go and doing what they want to do. The most obvious difference in the King Pin when compared to an alpine binding is the toe piece. It uses a tech toe piece that sports two spring-loaded pins to secure your boot, has a locking ski/walk switch, and features adjustable boot stops for easy step-in. The differences are in the 38mm wide mounting pattern for efficient power transfer on wide skis, and the spring configuration which uses Marker's Six Pack setup to provide greater energy absorption and contact pressure than a four-spring setup. This technology reduces unwanted release and gives you a smoother ride as you pop off pillows, rip through trees, or spin off of a backcountry jump.
