Union Astra Step On® Women's Snowboard Bindings 2027

Brand new for 2027, the Women's Union Astra Step On® brings together Burton’s proven Step On® Instant Connection™ System and Union’s renowned performance, durability, and ride feel. Designed specifically for female riders, it offers the fastest and easiest way to get locked in and start riding without compromising response, comfort, or control.

As the only Step On® partner that designs and manufactures its own bindings, Union has pushed the system even further, creating a seamless blend of convenience, power, and all-mountain performance.

Getting in is simple: step in heel-first, press down to engage the toe clips, and you're ready to ride. When it's time to get off, pull the heel release lever and twist out. Fast, intuitive, and hassle-free.

Built on Union’s Atlas Step On® baseplate and backed by a lifetime warranty, the Astra delivers legendary response and reliability. A Duraflex highback with adjustable forward lean provides precise control, while Hi-Flex EVA bushings absorb chatter and vibration for all-day comfort. New Non-Stick Hot Press EVA footbeds help prevent snow and ice build-up, keeping your setup clean and ready for every lap.

Union reliability meets effortless entry. Step in, ride hard, and step off with ease. The Women's Astra Step On® has arrived.
