Truly Reactive Dampening:

A BINDING IS THE SUM OF IT’S PARTS

Engineered To Perform

S11 ASYM Duraflex ST Baseplate

By removing excess material in the toe and heel of the baseplate, and utilizing a brand new asymmetrical shape, we've been able to drastically increase the torsional flex of the binding.

S15 Ultra Duraflex ST Highback

A thin layer of molecular bushing provides increased flexibility and a spring loaded return for quick edge to edge power when you need it.

Forma X Ankle Straps

Instant response meets all day long foot comfort. The Forma X ankle strap's all-new construction combines our responsive Exoframe exterior with the padded comfort and flexibility of the Forma interior.

Molecular Bushing

Union's all-new Molecular bushing provides spring-loaded take offs and perfectly cushioned landings. 15% lighter than Union Fused Vaporite and guaranteed to minimize foot, ankle and knee fatigue. This is the future of freestyle binding design.
