Women's All-Mountain Performance Meets Instant Step On® Speed

Engineered specifically for women who want high-performance freeride control paired with friction-free convenience, the 2027 Union Astra Step On lets you step into your line instantly. Designed to carve crisp morning corduroy at SilverStar, slice through variable snow at Big White, or navigate technical terrain up at Revelstoke, the Astra combines a responsive, carbon-infused frame with Burton's battle-tested Step On® interface.

• Women’s S1 Step On® Duraflex CB Baseplate: Carbon-injected nylon baseplate delivers lightweight rigidity for rapid edge-to-edge power transmission and high-speed stability.

• Step On® Instant Connection™ System: Dual toe hooks and a secure heel-latch connection allow you to click in and ride straight off the chairlift without bending down.
