Progressive Power | Maximize Energy | Optimize Performance
Rigid carbon fiber in footwear is good for one thing - going fast in a straight line. When running at slower speeds you have to work against it burning unnecessary energy and creating instability.
GearFlex (formerly known as DFX) engages stiffness as it bends, providing geared power as you achieve higher speeds, while remaining highly flexible at slower speeds. Its high flexibility underfoot moves with your natural gait to enhance your natural movement and maximize energy with every step, helping you optimize your performance.
Easily flexible in first gear for slower speeds and engages stiffness at second gear to optimize high speed movement.
Designed for powerful movements that maximize efficiency.
Flexibility provides support that moves with your movements.
Do more by carrying less.
