Product Highlights:
PUMA has once again broken the rules in the coolest way possible with the Fast-RB Nitro Elite 2. This shoe is packed with the potential to deliver remarkable race-day experiences in a package that doesn't feel (or look) like anything else on the market. Ignoring World Athletics official guidelines, PUMA has cooked up a beast of a shoe that is sure to turn heads as you fly by.
Where to begin? Let's dive into this innovative midsole. Underfoot, two carbon fiber plates are fused to form a cantilever structure. This essentially forms a pre-loaded spring under your feet that's ready to explode with energy and speed at any moment. Above, below, and between these plates is a top-tier racing midsole, fully composed of NITROFOAM Elite foam. This adds softness, cushioning, and extra propulsion underfoot to send you hurling towards the finish line.
As crazy as it looks, this underfoot experience has been carefully designed to work for any type of footstrike, from heel strikers to forefoot strikers. No matter how you land, this shoe will respond by rebounding wild amounts of energy for an underfoot experience unlike anything the running world has ever seen.
A thin, race-ready upper locks you into this unique platform, offering peak breathability and hints of padding where you need it most. Underfoot, you'll find PUMAGRIP LT, which has been specifically engineered to handle the intense forces that this shoe generates. It'll give you all the traction you need for aggressive speed, letting the cantilever do its thing without losing any forward momentum in the process.
This shoe isn't race legal, but the fun is real. PUMA is here to show us that they're not afraid to experiment, push limits, and put out original ideas. The Fast-RB Nitro Elite 2 (a concept car of a shoe) is a prime example of innovation, love for the sport, and what PUMA is all about.
