Meet the Fast-R3, our fastest running shoe ever. Data-driven, lab-tested, and designed for performance breakthroughs. Engineered in collaboration with elite athletes, the Fast-R3 delivers a 3.15% improvement in running economy*, potentially shaving over 4 minutes off a 3-hour marathon time.
We made it lighter by 95g compared to its predecessor, added even more height with enhanced NITROFOAM™ ELITE cushioning, and extended the carbon PWRPLATE for unmatched propulsion with every stride.
*Based on comparisons with the previous Fast-R NITRO™ Elite 2 model.
