Engineered with elite runners and tested on real athletes, Fast-R NITRO™ Elite 3 weighs an astonishing 95 grams less than its predecessor. The decoupled midsole has received a fierce upgrade, with a new NITROFOAM™ ELITE compound providing next level cushion and responsiveness.
The restructured PWRPLATE offers unrivalled propulsion and elite efficiency, whilst retaining the silhouettes iconic extension through the forefoot and out past the toe – a unique design and performance benefit that was first introduced in the Fast-R NITRO™ Elite 2.
A breathable upper is comprised of premium, lightweight ULTRAWEAVE that ensures comfort and support throughout race day, whilst PUMA’s industry leading PUMAGRIP outsole offers multi-surface traction to ensure you make it from start to finish with a new PB front of mind.
Debuting at the Boston Marathon 2025, Fast-R NITRO™ Elite 3 combines state-of-the-art technology with cutting-edge design, providing runners a rate of efficiency that could potentially shave minutes off your race day records - evidenced in a research study conducted by the University of Massachusetts, Amherst.
The study, led by industry specialist Wouter Hoogkamer, concluded that Fast-R NITRO™ Elite 3 provides 3.15% improved running economy*, which for a 3-hour marathon runner translates to an unprecedented potential marathon time saving of more than 4 minutes and 30 seconds.
Commenting on the findings, Assistant Professor at the University of Massachusetts Amherst Wouter Hoogkamer, who specializes in the biomechanics and energetics of running said: "The most striking result from this study was the consistency of the running economy improvements. For every single participant the numbers showed that running was easiest - requiring the least amount of metabolic energy - in the Fast-R 3. This is remarkable. From years of research we know that our lab-measured improvements in running energetics translate to faster race times."
