Less weight, enhanced cushioning and more energy with every step, the GT-2000™ 6 model delivers optimized performance and high-mileage durability. A widened forefoot accommodates bunions and reduces irritation, while the upper incorporates a better heel-fit to keep you locked down plus improved toe-spring for a smoother transition. The DuoMax® support system and heel-to-toe GEL® cushioning offer protective stability that absorbs shock on any surface.
