While developing the Ultra, Gigi Rüf and the engineers at Union had one goal: uncompromised board flex and feel. To create a binding that had these characteristics required reducing the contact points on the base and integrating flexible, dampening EVA. By combining Vaporlite 2.0 with the Minidisk, we've lowered the direct binding to board contact to 5% while maintaining the progressive flex that Gigi loves.
- Medium | 6-9
- Large | 9+
Highback Stiffness (1 Soft - 10 Stiff) – 8
Baseplate Stiffness (1 Soft - 10 Stiff) – 5
Duraflex CB - MD Base – Duraflex material was specifically engineered to maintain consistent flex in a wide range of cold temperatures. Union has exclusive rights on this brand of nylon, so you wont find it anywhere else. The Duraflex CB Base is lighter and considerably more stiff than typical fiberglass injected nylon parts. 5% binding to board contact allows for even board flex.
Vaporlite 2.0 – Vaporlite 2.0 is the evolution of closed cell foam often featured on high-end running shoes. Super durable and damp in a wide range of temperatures. Highly waterproof.
Non-Stick™ – New for 18/19 is the application of Non-Stick™ coating to Union EVA dampening systems. Gone are the day sof getting ice buildup on your footbeds and highbacks.
Forged Carbon – Exclusive to Union, Forged Carbon exceeds the strength requirements of injected plastic tenfold. Lighter is only better when it is also stronger. Forged Carbon is as light and strong as it gets.
Quick Adjust Forward Lean – Easily adjust the forward lean on the binding to dial in a custom ride.
Forma Elite Ankle Straps – Designed by Travis Rice, the Forma Elite Ankle Strap fits his riding style and minimal approach towards the perfect binding.
Hexgrip Toe Straps – Multi-positional options and thermoplastic anti-slip material keeps you locked in and on point. Each version has differing amounts of material based on weight.
Magnesium 3.0 – The evolution of Union's proven bombproof ratchet system, the Magnesium 3.0 is a lighter and more sleek upgrade.
