Stage 4 Duraflex Base: Blended to provide a smooth and responsive ride, Duraflex ST Nylon retains this intended performance in a broad range of temperature.
Multi-Density Thermoformed EVA Bushings: These bushings sustain their function season after season – like competitors who use urethane, rubber, or other materials that change color and become hard or brittle over time.
Force Highbacks: Duraflex Injected Miltizone Force Highbacks are tapered towards the top providing flex and tweakablility where you want it, support and durability where you need it.
Extruded 3D Aluminum Heelcups: Aluminum for rigidity and strength. Acts like a roll cage on a rally car, stiffening the entire binding as a whole, seamless response.
Symmetric Sonic Fused Ankle Straps: Three Dimensional Direct-Connect core evenly distributes strap pressure and allows lateral freedom. Minimized stitching provides exceptional durability.
Magnesium Ratchets: Union exclusive material, feel special! Provides 4x the strength of aluminum while cutting weight by almost 50%. PLUS magnesium is easily recyclable and remains the 8th most abundant element on the planet. That makes Union not only smart, but COOL!
