FAST-R NITRO™
We engineered Fast-R3 in the lab, controlling every variable. The result? The fastest running shoe we’ve ever made – data-backed, lab-tested, and built for breakthroughs. Designed to shave minutes off your race time, Fast-R3 has a 3.15% improved running economy*. For a 3-hour marathon runner, that means saving more than 4 minutes and 30 seconds. Fast-R3 is 95g lighter than its predecessor, with a higher stack of new and improved NITROFOAM™ ELITE and an extended carbon PWRPLATE for maximum propulsion. You can’t predict where race day will take you- but you can trust that the tech under your feet has been optimized for you to have the time of your life.
