M FAST-R 3

Fast-R3 is the fastest running shoe we’ve ever made – data-back, lab-tested, and built for breakthroughs. After testing it on elite runners and real athletes, we digitally engineered and optimized the product fully based on data. Fast-R3 is designed to shave minutes off your race time. With its 3.15% improved running economy*, this translates to an unprecedented potential marathon time saving of more than 4 minutes and 30 seconds, for a 3 hour marathon runner. We cut 95g from its predecessor, stacked it higher with new and improved NITROFOAM™ ELITE, and extended the carbon PWRPLATE for maximum propulsion. *Compared to the PUMA Fast-R NITRO™ Elite 2
