Built to last.

The All-New Union STR is the binding for stepping up to larger drops and more technical lines. For riders looking for the performance of the Atlas at a price that's nice, the STR maintains everything you would expect from our high end Canted Stage 5 Base, TR16 Highbacks and Bone-Out straps make choosing the STR a no brainer.

Super tough - With an unprecedented performance for the price, the STR represents our philosophy that there is no such thing as “entry level” in the Union family of bindings. Constantly investing and reinvesting into product is what sets Union apart from the competition.

Canted power - Ideal for riders using a wide stance, Canted Gas Pedals on the STR supply extra leverage and ollie power. Canting also allows the ankle and knee joints to be aligned, alleviating pain.

Features:

Stage 5 duraflex base - The ST Stage 5 Base is perfect for All Mountain / Freeride based riders looking for serious bang for the buck. Canted and bombproof, the ST blows away everything in its class.

Multi-density thermoformed Eva bushings - Multi-Density Thermoformed Bushings sustain their function season after season - unlike competitors who use urethane, rubber or other materials that change color and become brittle over time.

Extruded 3D aluminum heelcups - The rigidity and strength of Extruded Aluminum acts like a roll cage on a race car - stiffening the entire chassis. The male/female connection with the base provides seamless response.

ST symmetrical highbacks - Symmetrical modern fitting ST Highbacks feature a multi-layered nylon design that is ideal for all around heelside support and control.

Bone out ankle straps - Light as a feather and super comfy, Bone Out straps feature a 3D Symmetric design that eliminates foot pain across the top of the foot.

Aluminum ratchets - Fast in and fast out - this new mechanism combined with Union aluminum is superior to any binding ratchet on the market - with the execption of Union magnesium.
