What Our Gearhead(R) Experts Are Saying:"I put the Astra Step-On Binding through a full resort day, and the Step-On entry system genuinely changed the pace of the whole session, clicking in at the top of every run in seconds and letting me focus entirely on riding rather than gear. The medium flex felt confident and comfortable across groomed terrain and softer snow alike, and the Hi-Flex HP EVA bushing kept things smooth and forgiving through a long afternoon of hard lapping."The lift unloads, the run opens up ahead, and the Astra Step-On Binding from Union is already locked in and ready to go. New for 2027 and built specifically for all-mountain riding, the Astra brings the speed and convenience of the Step On Instant Connection System together with Union's proven medium-flex performance in a package designed to keep the focus exactly where it belongs, on the riding. Click in heel-first, press down on the toes, hear the clicks, and go. The S1 Step On W Duraflex ST baseplate and matching highback form a platform built for consistent performance across cold temperatures, with high-fiberglass construction that delivers response without adding unnecessary weight. The Hi-Flex HP EVA bushing acts as an additional layer of dampening between boot and board, protecting knees and ankles through a full day of varied terrain while never losing its shape over time. The Integrated 2-Stage FLAD lets us dial in forward lean trailside without any tools, so the setup stays perfectly tuned from the first groomed run of the morning to the last soft-snow lap of the afternoon.
