The GT-2000™ 11 GTX shoe is designed with a GORE-TEX™ membrane that helps keep your feet warm and dry when running in wet or snowy conditions. We've updated the underfoot cushioning to make it feel more comfortable and energetic. Key adjustments in the midsole include our 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.​
