FJ Stratos with STRATOFOAM, a proprietary cushioning system engineered from a unique compound blend that allows each shoe to absorb shock and return energy. The main benefit of energy return is that, each shoe works for you, which can help reduce foot fatigue after a round of golf. Unlike other competitive shoes that use cushioning systems for running, resulting in high impact construction, FJ Stratos golf shoes are specifically tuned for golf/walking.
