PositiveThey own several pairs of the Alphafly 3 and still call it their clear favourite among the super shoes they have tried. They describe it as user friendly and usable over very long distances as well as at high speed.

MixedFound the Alphafly 3 very fast and comfy but it lost all bounce and support after 180 miles, and is loud.

PositiveA runner set their 10K and half PRs in the Alphafly 3, praising its balance of aggressiveness and cushion, though the Adios Pro 3 is comfier.

MixedThey ran a marathon PR about four minutes faster in the Alphafly 3 but found it overly slappy underfoot and regretted the choice late in the race.
YouTube · Steven Neeson · Dec 9, 2024 · summarized
MixedAfter several months in the shoe, including two half marathons, they first disliked it because it hurt their arch and took many miles to get used to. They later found it comfortable, breathable and fast, but more aggressive than expected and not as comfortable late in a race as their Alphafly 1, so they prefer it for 10K and half marathon. They also report stones lodging in the outsole and faster wear than an older Alphafly 1 pair.

Positive'The Return of the King.' Comfortable, light, fast and bouncy, everything a race-day shoe should be. One tester puts it as 'this shoe and the rest'. Another also likes rivals but rates it uniquely. The previous version had twisted one tester's knee; this one fixes the platform.

PositiveTesters praise the 24g weight drop, terrific upper, smoothest transition yet in the line and strong energy return. Cons: the Zoom Air pods feel mechanical, it may not suit those wanting an aggressive racer, and the laces do all the lockdown. One tester got arch rubbing at ~16 miles.
Blog · Doctors of Running – Andrea Myers, David Salas (DPTs) · summarized
MixedOne tester: his favourite in the line and the shoe he grabs to run fastest, though the midfoot ZoomX slides. Another: best at 5K-half pace and sluggish at marathon pace. The short, low toe box bruised her big toenails, and the foam wears early.
Blog · The Running Channel – Mark Dredge / TRC team · summarized
PositiveFast and propulsive. The team pair began losing responsiveness at ~200 miles but is still usable for training. Jogging in it feels ineffective, it's unstable at slow paces, and it needs strong feet and lower legs.

PositiveNike's best racer yet: lighter and more aggressive than the AF2, comfortable for marathons, and it helps you hold pace when tired. No undue wear after 80 miles. Very expensive.

PositiveCalls the Alphafly 3 their favorite racer: they own two pairs, have set 5K and 10K PRs in it all year, and find the upper fits perfectly and the midsole feels amazing.

PositiveTook their Alphafly 3 out for an 8-miler after months off and was reminded how good and fun they are; they bought a second pair as a backup.

PositiveA 47-year-old set a 5K PR in the Alphafly 3 at a lower heart rate: super comfortable, bouncy, no arch issues, surpassing the Vaporfly 3.

PositiveOn their first 9 km in the Alphafly 3 it felt impossible not to go fast; an intended easy run kept drifting well below their planned pace.

PositiveA 2:56 marathoner who raced Houston in the Alphafly 3 finds it has the Vaporfly 3's benefits plus better lockdown, more cushion and more propulsion, and plans to wear nothing else for the marathon.

PositiveFinds the Alphafly 3 far more comfortable than the first Alphafly, with no arch discomfort and a toe box that no longer feels baggy; it still feels very fast and they set a 5K best in it.

PositiveOn an 8.5 km interval run, a 1:41 half marathoner found the Alphafly 3 awkward slow but great fast, with lower heart rate than the EP3, crazy light, and no heel slip.
Most runners find the Alphafly 3 comfortable, bouncy and stable, praised for racing and long efforts, with a roomy toe box and good heel hold. Downsides are noise that many notice and foam some feel loses its pop within a few hundred miles, though others report much longer life. It can feel clunky at slow paces.
