If you ride at the edge of two sizes, size down for a responsive, locked-in feel or up for a more relaxed fit. Boots should sit snug inside the binding with no heel lift. The Ultra Women's uses the same chassis as the Men's Ultra with women's-specific tuning and colorway.
Component Breakdown
S11 Duraflex ST Baseplate
By removing excess material in the toe and heel of the baseplate and utilizing an asymmetrical shape, Union drastically reduced weight without sacrificing strength — paired with their next-generation suspension bushing for unmatched dampening. Backed by Union's lifetime warranty.
S25 Ultra Duraflex ST Highback
NEW for 2025. 6 degrees of preloaded forward lean hugs your boot and allows for quick edge-to-edge response. Now available with forward lean adjustment via the integrated 2-Stage FLAD. Pro team tested by Arthur Longo and Gigi Rüf.
Hybrid 1.0 Ankle Strap w/ PU Core
ExoFrame exterior with the padded comfort and flexibility of the Forma interior — instant response meets all-day foot comfort. The Hybrid 1.0 gives the Ultra Women's power without pressure points, perfect for riders who want responsive support that doesn't fight back.
TS 5.0 UltraGrip Toe Strap
Multi-positional options and thermoplastic anti-slip material keep you locked in and on point. The TS 5.0 UltraGrip easily shapes to any snowboard boot for maximum grip from all angles.
Magnesium S1 Ratchets w/ Steel Base
Union's newest ratchet — longer life span and better spring return guaranteed. A fully integrated spring protected from the harsh outside gives you Union's best-in-class ladder action run after run.
Extruded 3D Aluminum Heelcup
Designed for optimum heel hold and minimization of drag. Backed by Union's lifetime warranty — the core of every Ultra binding is built to last.
Moleculer Bushing w/ TPE Outsole
Union's next-generation suspension bushing delivers cushioning and rebound without bushing gluing required. Pairs with the Duraflex footbed and ExtraGrip under the big toe for a damp, locked-in ride.
Integrated 2-Stage Forward Lean Adjuster
Fine-tune your forward lean angle with a #3 screwdriver to match changing terrain and riding styles. On-the-fly adjustability without removing the binding — quick, tool-assisted tuning.
Grade 8.8 Steel Hardware
The strongest steel available on the market. Comes pre-installed so you can mount and ride without a hardware run to the shop.
