The Fast-R3 is the fastest running shoe we've ever made. Data-driven, lab-tested, and engineered to revolutionize running, it's been digitally engineered and optimized based on data. The Fast-R3 is designed to shave minutes off your run. With a 3.15% improved running economy*, it represents an unprecedented time savings of over 4 minutes and 30 seconds for a 3-hour marathoner. We've shaved 95g off its predecessor, beefed it up with new and improved NITROFOAM™ ELITE foam, and PWRPLATE carbon technology for maximum propulsion.
