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

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.

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.

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.
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.
