The GT-2000™ 11 is a stable and versatile trainer, ideal for covering different distances. We've improved the cushioning underfoot to make it more comfortable and dynamic. We've modified the midsole by introducing our FF BLAST™ cushioning. This soft material promotes more cushioned landings and a responsive rebound. LITETRUSS™ technology is positioned inside the midsole to improve stability. Prevents the foot from rolling inward too much to allow for a smoother stride.
