The original Puma Fast-R Nitro Elite turned heads with its eccentric design, which featured a decoupled midsole with separate chunks of foam under the heel and forefoot.
Puma has kept the decoupled design, but made other notable changes such as increasing the stack height and using a new midsole foam. The Puma Fast-R 2 is a bouncy and impressively propulsive racer, especially for the marathon, and stands up well against the best carbon plate running shoes—even if there are some I prefer like the Nike Vaporfly 3 and Nike Alphafly 3.
