The Force Pro offers everything you know and love from the classic Union Force, just a little bit better. The binding comes with Union\'s best straps - ExoFrame 5.0 ankle straps and ultralight TS 4.0+ toe straps with super durable magnesium S1 buckles. The Union Force Pro stands for reliability and unsurpassed durability. Highback The Team Highback with medium to hard flex, comes with a super light, freestyle oriented design. Duraflex material is specially designed to provide consistent flex over a wide temperature range. The angle of the highback (forward lean) can be adjusted without tools. Baseplate The Stage 4 baseplate with medium to hard flex, is made of Duraflex ST nylon. This material offers stiffness and responsiveness that will last season after season. The multi-density, thermoformed EVA bushings provide excellent cushioning, even in cold temperatures. Straps The ExoFrame 5.0 ankle straps are the ultimate connection between boot and binding. The progressive flex allows for quick response and power transfer for demanding riding at high speeds. Simple, lightweight, durable - The TS 4.0+ toe straps keep your boots bombproof and secure in the binding without you even knowing it\'s there. A shorter contact surface for the buckle saves weight and reduces pressure points. The Magnesium S1 buckles are made of magnesium and aluminum. A good combination of lightness and stability.
