Instant connection. Instant response. The all-new Union Atlas Step On combines the proven convenience of Step On technology with Union’s renowned all-mountain performance. Featuring the Step On Instant Connection System, this binding delivers lightning-fast entry and exit without sacrificing response, precision, or power. Built for riders who demand speed, efficiency, and top-tier performance from first chair to last lap.

Fast in, fast out. The Step On Instant Connection System is the only automatic binding system that meets Union’s standards of performance, durability, comfort, and function. Simply step into the binding heel-first to engage the heel clip, then press down on your toes until you hear the clicks. When it’s time to get out, pull the lever on the heel of the binding and twist your foot. It’s that easy.
