All of the best marathon racing shoes have a unique feature that sets them apart from the rest, but none of them embodies uniqueness and innovation quite like the Nike Alphafly 3. Just by looking at it, you can tell that it’s a fast and special shoe. Although this shoe stands out in every way, the star of the show is the midsole design. For the first time in the Alphafly series, the midsole now features a continuous bottom layer of ZoomX cushioning that promotes smoother transitions and increased propulsion while still offering an incredibly soft ride. Sandwiched between the top and bottom layers of ZoomX foam lie the quintessential staples of the Alphafly, the two Air Zoom Units and carbon-fiber Flyplate. These two elements work together to launch you into your next step, making running faster feel easier.For improved stability over long distance runs, the full-length carbon fiber Flyplate has been widened which also helps deliver a more propulsive sensation underfoot. Additionally, the Alphafly 3 has a widened base, which makes it more accommodating for the non-elites who still want to experience the top end speed this shoe brings to the table. With increased speed comes the need for confidence-inspiring traction, and the fast shot outsole balances the need for grip without compromising weight. Meanwhile, the updated Atomknit 3.0 upper dials in the fit and keeps your feet comfortably secure from start to finish. Overall, the Nike Alphafly 3 continues its legacy as a pinnacle marathon racing shoe that is bound it etch its name in the story of your best race.
