3/10/2023 0 Comments Nike air zoomDuring a six-mile run, I didn’t notice any slippage within the shoe. It’s the same material that was used in 2020, but this time around it’s been engineered with zones that stretch or lock your foot down as well as more dense containment around the forefoot to keep it in place-a much appreciated feature for someone like me, whose toes suffered significantly over the course of two marathons in the original. One big area of improvement is the Atomknit 2.0 upper. As an added bonus, this rubber makes the shoe a little quieter (shoes with this much foam in them tend to make hollow popping sounds as they hit the ground). Before, I was afraid to wear the first-gen on anything other than super flat pavement, so that extra bit of tread was very welcome when I tried running in the second-gen on a bridle path next to my standard sidewalk route. Nike actually changed the outsole material to a new, more durable rubber with better traction so they could use less of it and replace some of it with ZoomX foam. That additional responsiveness underfoot could be due to the fact that a few millimeters of ZoomX foam now wraps around under the Zoom Air Pods, giving you more energy return with every step. During a speed workout, I ran by feel during the harder efforts, and was genuinely surprised by just how fast my paces were (I didn’t feel like I was working that hard!) when I looked at my data afterward. Nike also increased the heel-to-toe offset from four millimeters to eight, a noticeable tilt that encourages a more natural foot stance, tipping you onto the Air Zoom pods so you can capitalize on that propulsive feel. RELATED: I Ran My Fastest 5k Ever in the Nike Pegasus 38 Runners who felt unstable on the original’s super cushy, but somewhat teetering, 35- to 39-millimeter stack height will appreciate the wider heel on the new version that larger footprint makes taking turns at high speeds slightly less stress-inducing, and keeps you on pace when it counts. At first glance, the new Alphafly 2 doesn’t look too different from the first iteration, but subtle changes improve the shoe’s stability and transition from heel to toe to help you feel as fast during mile 26 as you did during mile one. (And, thankfully, they did it without increasing the already steep $275 price tag). And that’s just what Nike did with the Alphafly 2, which was just announced today. You can’t fix what isn’t broken, but you can improve upon it. And Nell Rojas made headlines at the 2022 Boston Marathon when she broke her contract with Adidas and ran in Nike, because Adidas’ carbon-plated racing shoes didn’t work as well for her as the Vaporfly and Alphafly shoes.ĮNTER TO WIN: A Pair of Nike Alphafly 2’s (before 06.30.22) How the Nike Alphafly 2 Has Changed Olympic Marathon Trials qualifier a pair of Alphaflys in Atlanta in March 2020. The OG was a bona fide hit: Eliud Kipchoge wore a prototype to break the sub-2 marathon in Vienna in October 2019. When the company first introduced the Nike Air Zoom Alphafly Next% in 2020, it was designed with a midsole made from a combination of full-length ZoomX foam (the brand’s lightest and most resilient), a full-length curved carbon plate, and dual Nike Air Zoom pods under the forefoot.
