PUMA released a colorway on August 26 that is designed to be seen from a helicopter. ‘Sunny Lime’ arrives on the FAST-R NITRO Elite 3 at $300 in style code 312060_15, a vivid neon green upper carried across the whole shoe and set against a dark speckled outsole. It is not a general release dressed up for autumn. PUMA built it for the fall racing calendar and put it on athletes at Berlin and Chicago before most buyers will see a pair in person.
The FAST-R is the strangest-looking race shoe any major brand currently sells, and that is deliberate. Where almost every carbon racer is a single continuous slab of foam, PUMA splits the FAST-R midsole into two decoupled sections, separating what happens under the heel from what happens under the forefoot. The idea is that a runner striking behind the midfoot and a runner rolling through the toe are asking the platform for different things, and one uninterrupted piece of foam has to compromise between them. PUMA has now run that architecture through three generations, and the third is the one that stopped being a curiosity. It is the shoe PUMA’s marathon roster actually races in, which is a sentence the brand could not have written about its running program a decade ago. PUMA spent the 2010s largely absent from serious road racing, and the route back was not a heritage reissue or a signature athlete. It was a platform weird enough that the running press had to explain it, which turned out to be a more efficient way to be noticed than another white racer with a plate in it.

Underneath ‘Sunny Lime’ the hardware is unchanged from the rest of the Elite 3 range. PUMA lists the shoe at 170 grams in a UK 8, with a 40mm heel and 32mm forefoot stack for an 8mm drop, built on NITROFOAM Elite and a carbon-fiber PWRPLATE. What the colorway does is push the green through the midsole foam rather than stopping at the upper, so the NITROFOAM sidewall reads as part of the same block of color instead of a white base under a bright shoe. The speckled outsole is the only place the design goes dark. PUMA also points to a University of Massachusetts Amherst study when it describes the shoe’s efficiency, and that is PUMA’s citation rather than an independent finding, so treat the efficiency claim as the brand’s own.
The same colorway lands on the Deviate NITRO Elite 4, which PUMA prices at 250 euros in the release. Two elite shoes, one loud color, dropped into the two weeks before the biggest races of the season.

That is the part worth paying attention to. Putting a single unmissable colorway on every elite shoe at once is not a design choice, it is a broadcast strategy, and Nike wrote the playbook for it when volt turned a television camera into free media for months. PUMA is running the same move with a smaller roster, and the reason it can is that its race shoes are finally on enough fast feet for the color to register. The risk is the flip side of the same coin. A colorway this specific to one season ages badly on a shelf, and PUMA is betting that the shoes sell through on race-day demand rather than sitting into spring in a green nobody wants by March.
At $300 the FAST-R NITRO Elite 3 is at the top of the running market and PUMA is not pretending otherwise. That is roughly double what a fast daily trainer costs, and it buys a shoe with a service life measured in races rather than months. Nike’s Pegasus Plus 2, a plateless tempo trainer released in the same window, is $170 for a shoe meant to absorb weekly volume. The Deviate NITRO Elite 4 sits below the FAST-R in PUMA’s own hierarchy at 250 euros. Anyone shopping this tier already knows the math. The shoe is a race-day expense, not a training one.

The ‘Sunny Lime’ FAST-R NITRO Elite 3 launched globally on August 26 at $300 in style code 312060_15, and is available on PUMA.com, at PUMA flagship stores and through select running retailers worldwide.
