The FLEX NRG is the gold standard for ergonomic comfort. The patented Soft Strike™ zone, which acts like the shock-absorbing midsole in your athletic shoes to absorb shock and reduce "footslap" noise, coupled with the biomechanically-designed FLEX Tail™ makes the FLEX NRG a dream for your joints. With the set-and-forget 180FLEX™ binding, and the FLEX Series 3D-curved Traction rails, the FLEX NRG is designed to keep you secure for your all-day treks.
