The GT 2000 11 is a versatile stability trainer that's functional for various distances. With updated FF Blast cushioning promotes softer landings and a responsive rebound. LITERUSS technology is positioned on the inside of the midsole to improve stability, and help prevent the foot from rolling too far inward, setting you up for a smoother stride. The midsole and outsole designs have also been reconfigured to produce a trampoline effect at toe-off. As a result you'll experience a more energized ride that helps propel you toward a new personal best.
