FootJoy poured all of its class-leading footwear technology into the all-new�HyperFlex, finely tuning every aspect of the shoe to meet and exceed the uncompromising comfort, stability, power, and traction standards the company reserves for its flagship offerings. FootJoy's proprietary StratoFoam midsole and Opti-Flex outsole address the first portion of the equation. This proprietary foam absorbs shock and returns energy with every step, while the serpentined sole plate bends with the foot's natural movement, ensuring all-day comfort and reduced walking fatigue. Elite traction and stability are paramount characteristics of FootJoy's tour-caliber shoes, and the HyperFlex is not lacking in either department. Powered by LB Pulsar cleats, additional traction elements, and FootJoy's TurFIT System, the HyperFlex keeps your feet locked in throughout the golf swing. Finally, and most impressively, the HyperFlex optimizes your swing's ability to generate speed. FootJoy accomplishes this with a PowerPlate and a TPU saddle harness, which reduce twisting and harness movement at the top of the foot, thereby improving energy transfer to the ground. Virtually all modern professional golfers use ground force to build swing speed, and HyperFlex's advanced construction maximizes the foot's ability to do so. FootJoy backs the HyperFlex with a two-year waterproof warranty.
