Astra Step On Women Snowboard Bindings - White 2027 FAQ
What's Step On and why would I want it?
Step On is Burton's boot-to-binding connection system. No straps, just step in and lock. Instant entry and exit, especially valuable for flat terrain, apres sessions, and reducing fatigue. Requires Burton Step On compatible boots.
Is the Astra Step On the first women's Step On binding?
Yes. The Astra Step On is the first women's-specific Step On all-mountain binding, combining Step On convenience with women's performance. S1 Step On W Duraflex ST baseplate and Hi-Flex HP EVA deliver 9/10 all-mountain response.
How adjustable is the Astra Step On?
Very. It has an adjustable gas pedal (fore-aft toe piece) and Integrated 2-Stage forward lean adjustment. Dial in your preferred setup for custom fit and stance angle, tool-free.
Is the Astra heavier than traditional bindings because of the lock mechanism?
No. At 1.60 kg (pair), it's competitive with traditional all-mountain bindings. The Step On mechanism is integrated into the heel, not an extra weight penalty.
