Reviewers who wore both
Direct paired observations — reviewers who actually ran in both of these and wrote the contrast. This is the strongest comparative signal on the page.
Solid pick for marathon super shoe without the AirPod feel, especially for heel strikers
Alphafly 3 has more trampoline bounce and responds better at 5K paces; Endorphin Elite is more predictable, falls into rhythm more easily, and is a bit more comfortable through the midfoot for marathon efforts.
The Alphafly 3's ZoomX and air units feel more present and aggressive versus the Elite 3's softer, more absorbing foam; the Alphafly 3 also runs narrower/more containing than the wider Elite 3.
Similar weight and bouncy ride but more controlled, purposeful and stable
Nike Alphafly 3 — what reviewers say
Ride profile: high cushion , balanced feel , high energy return , neutral stability , moderate rocker.

A capable marathon race shoe with a distinctive high-arch fit that may not suit everyone.
In their words: "world's noisiest race day shoe"
-
A durable, solid half/full marathon shoe, though too much shoe for 5K/10K efforts. Tier B.
In their words: "a really solid half or full marathon shoe" · "very resilient foam and air unit combo"
-
Ben's marathon PB shoe — a top super-shoe pick with PEBA foam and carbon plate, offering exceptional protective cushioning for long race distances.
In their words: "ran my personal best in the marathon"
-
The Alphafly 3 is eliminated in the group stage, described as a former great that is aging gracefully but no longer at the top.
In their words: "a former great, aging gracefully, but still not quite getting through"
Saucony Endorphin Elite 3 — what reviewers say
Ride profile: high cushion , neutral stability .
-
Despite costing £70 more and running heavier, Parkes found the Endorphin Elite v3 softer, bouncier and noticeably faster than the SC Elite v6 in a half marathon outing, and says it's the shoe he'd pick between the two.
In their words: "really quite a lot softer" · "a lot more bouncy" · "I just run so much faster"
-
A race-shoe runner-up pick; the reviewer calls it one of the softest, bounciest race shoes around and a likely choice for an upcoming marathon.
In their words: "softer bouncier"
-
His standout favorite of the tier list — wildly soft, compressive yet reactive, superbly light with an exceptional, foot-shaped upper. Tier S.
In their words: "it just seems to handle changes of pace very, very well" · "an S tier for me"
-
On a first run, praised as by far the softest and bounciest super shoe the panel has tried, well suited to longer straight-line racing, though cornering control is a weak point.
Ride:First-time run in the shoe; tall sidewalls and dialed-in geometry make it a strong straight-line performer that responds well when the runner leans forward and engages the leg, but turning felt harder/less controlled than some other super shoes, and the soft PWRRUN foam bottoms out at top-end speed.
In their words: "the softest and bounciest super shoe" · "controlling it is another story"
