The GT-2000 11 shoe is a versatile stability trainer that's functional for various distances. Asics updated the underfoot cushioning to make it feel more comfortable and energetic. Key adjustments in the midsole include FF BLAST cushioning. This soft material helps promote softer landings and a responsive rebound. LITETRUSS technology is positioned on the inside of the midsole to improve stability. It helps prevent your foot from rolling too far inward, setting you up for a smoother stride.
