Nike Air Zoom Alphafly Next% 2: First Runs and Early Verdict

Introduction

The Nike Air Zoom Alphafly Next% 2 arrived as a bought-with-own-money purchase rather than anything sent for review, and the first impression is that this is not simply the original shoe with a fresh number. It is slightly heavier, noticeably wider and built around a clearer purpose: half marathon to marathon racing.

In a UK size 11, which corresponds to a US size 12, it weighs in at 278g, about 9.8 oz, roughly 12g heavier than the Alphafly Next% 1. Underfoot it is wider too, with around 3mm of extra width in the mid-to-forefoot and a couple of extra millimetres in the heel, which points to a more stable ride. The measured heel stack came out at a colossal 46mm, suggesting something closer to a 6mm drop in practice than the claimed 8mm, and it feels little different lengthwise from the original. At bang on 29cm it runs true to typical Nike sizing.

Upper: Stiffer, Padded and Harder to Get On

The upper has more in common with the Nike ZoomX Streakfly than anything else, though some knit sections recall the Infinity Run Fly. Compared with the almost floppy knit of the first Alphafly, the toebox here has a much more rigid, coarse feel and stands exactly where it needs to be. There is also more reinforcement around the front of the toebox, which should help durability over time.

The tongue is far thicker than on the original, with a very flexible knit over the top of the foot, and the ankle padding is genuinely addictive to squash. The laces are perforated and barely need tying, staying fastened through initial runs without any issues, and less lace pressure is needed for a good lockdown. Toebox depth is roughly the same as version one, and breathability was adequate on a relatively warm run.

Two caveats stand out. The shoe is genuinely difficult to get on, thanks to an enormous pull tab that you will definitely need, and it only loosens up after three or four wears, which makes it a poor match for triathletes. The upper also gave a little over the first few miles and required a re-lace mid-run, so bank a couple of longer runs in these before using them for a peak race. As a score after initial runs: 2.8 out of 3.

Midsole: More Stable but Less Versatile

The midsole now cups around the foot, creeping up around the toebox and the heel, so it looks like there is considerably more foam than there actually is. The gains over the original are negligible in practice. Contrary to suggestions that the arch is less present than before, the larger insole Nike includes simply covers it up; anyone who had an issue with the arch in version one will find the same here.

The easy-to-catch heel flare is mostly gone, though the very end section of the midsole still seems like a pointless point of failure. Nike has added a touch more foam under the Air pods, which makes the shoe a touch quieter than the clattering original, and the foam no longer creeps out and spills as much at the sides. The trade-off is that any debris that works its way in around the Air pods will now be much harder to remove.

In terms of finish, the midsole foam is shoddy: little bits hanging off from the mould and glue marks everywhere, which stings at this price. On the run itself, testing at half marathon and marathon pace, the ride felt great: smooth, very stable and more assured around corners and bends. Nike has repositioned this as the half marathon to marathon shoe with maximum cushioning, and the roughly 40g difference versus the Vaporfly Next% 2 underlines the split. At 5K or 10K pace it is simply too much shoe, and as an everyday trainer it is overkill, especially in larger sizes. The PrimeX offers superior cushioning for its extra 6-7mm of stack. After initial runs: 2.7 out of 3.

Outsole: A Genuine Upgrade

The outsole setup has changed greatly and should make this a more durable shoe that can handle more frequent use. Thicker rubber in the heel and a redesigned mid-to-forefoot with a mass of protruding and inverted lugs should deliver strong traction, with more rubber and more coverage across the whole outsole. Most of the extra weight lands here.

Grip was reliable on initial runs across various terrains, and it felt secure enough that lighter trail settings and grass are plausible, something the original was not great at. Grip at higher speeds was great, and considering the rubber has been minimized, there is no compromise on traction. After initial runs: 2.9 out of 3.

Value: Punishingly Expensive

There is no escaping it: this is a punishingly expensive shoe at £275. Taking it out of the box, the thought was whether it could really survive being run in, but it held up, and there is no reason not to hammer through several hundred miles, as long as the Air pods stay puncture-free. Based on how well the original held up, looking nearly untouched after 100 miles, durability looks promising.

The wider, heavier package means this is now one for half to full marathon runners, and its versatility has dropped. The Vaporfly Next% 2 remains the more versatile super shoe, and for anything at 5K to 10K pace there are far cheaper models that are much better value. Nike appears to be aiming this at a mass-market marathon audience, whatever pace they run, in the way the Air Jordan line became a mainstream product rather than a niche one. After initial runs: 2.5 out of 3, bringing the overall total to 10.8 out of 12.

Conclusion

The Alphafly Next% 2 is a more stable, better-tractioned and likely more durable shoe that has traded some versatility for a clear identity as a maximum-cushion half marathon and marathon racer. If you are training for or racing a marathon, it is a fantastic tool, and using it for its intended purpose rather than keeping it babied in a box is the right call. If your racing lives below half marathon distance, look elsewhere: the Vaporfly Next% 2 is still the more versatile pick, and cheaper models make far more sense at 5K to 10K pace.
