CAST Backcountry Skiing Alpine Binding Adapter

The CAST Binding system in all its glory.

The CAST Binding system in all its glory.

When a couple of good ol’ boys from Vermont corner you in Salt Lake City you know something is up. I knew I was safe from being converted but would they let me in on some secret cheddar cheese? Or a few sips of maple syrup? Not quite, but they did give me the run down on a new binding plate system they’ve been working on for the last 3 years.

I’ll let the pictures tell the story.

From their site, “CAST is derived from the collective noun for a group of hawks and named in honor of Green Mountain Freeride founding member Ryan Hawks. Ryan possessed an indomitable spirit and never ending love of life. It is CAST’s mission to honor Ryan’s spirit and all of those we have lost in the mountains, by creating quality products which allow for easier access and greater enjoyment of those special places where we are closest to them.”


Lars Chickering Ayers and brother Silas have been ripping up the Freeride World Tour for a few years now. Both have come to a realization that they needed a system for touring and dropping into some of the steepest lines with the biggest cliffs in the world. Behold the CAST touring binding.

The latest video from the guys at CAST.

The plate is secure by a welded bar system inspired by the safety mechanism on your favorite high powered rifle.

Once fully engaged forward the boot has moved approximately an inch forward on the plate system. This is to prevent the boot from going from tour to ski mode.

Rubber bands have been tested and proved to be the most effective at holding the brakes up. Note additional lifter plate below the heel ensures a flat interface between toe and heel when in ski mode.

The CAST boys are also offering a service for around $100 to retrofit any race boot plug with their own in-house forged tech fittings and new soles. This is for the toe only.
