Nike Alphafly 3 vs Adidas Adizero Adios Pro 4:
Which to Choose

October 17, 2026

Verdict

These are two of the best marathon super shoes made, and both will race brilliantly in the hands of a fast runner — so the choice comes down to ride feel, fit, and range rather than quality. Go Alphafly 3 for a soft, explosive, bouncy ride, a roomier fit, and a pure half/marathon focus; go Adios Pro 4 for a firmer, rocker-rolling feel, a narrower snug fit, a lower drop, and the versatility to race everything from 10K to the marathon. Try both on if you can: your foot shape and whether you prefer bounce or roll will settle it faster than any spec sheet.

Who Should Choose Each Shoe

Choose

Nike Alphafly 3

Choose the Alphafly 3 if your focus is the half and full marathon and you want the maximum, cushioned, trampoline-like bounce to carry you through the late miles. It suits a powerful runner who lands and drives off the forefoot, wants a slightly roomier upper and wider base underfoot, and can reliably hold the fast, committed pace the Air Zoom pods demand. If you've raced in previous Alphaflys or Vaporflys and like a soft, springy, propulsive feel over a firm one, this is the natural pick.

Choose

Adidas Adizero Adios Pro 4

Choose the Adios Pro 4 if you want one racer that spans 10K through the marathon and prefer a firmer, rocker-driven ride that rolls you forward rather than bouncing you up. Its lower drop and snug, narrow fit favor a runner with a quick, efficient forefoot turnover and a lower-volume foot who wants an agile, direct connection to the road. It's the better fit for someone whose racing calendar mixes shorter road events with the marathon rather than targeting the longer distances exclusively.

Head-to-Head

On paper these two are strikingly close: both are neutral, low-stability platforms rated 6/6 for pace and responsiveness and 5/6 for cushioning, both ride near the ~39–40mm max stack, and both want you running at roughly 3:00–3:20 min/km before their geometry truly clicks. The core difference is how they generate their propulsion. The Alphafly 3 uses ZoomX foam with twin Air Zoom pods under the forefoot and a full-length carbon plate, producing a soft, almost trampoline-like pop off the toe — a bouncy, explosive ride that rewards power. The Adios Pro 4 instead pairs dual-layer Lightstrike Pro PEBA with carbon-infused EnergyRods and a pronounced rocker, giving a firmer, rolling, tipping-forward feel that insists on quick turnover rather than spring. Drop separates them too: the Alphafly sits at 8mm, while the Adios Pro 4 is lower at around 6mm, putting you a touch more onto the forefoot. The Adios Pro 4 is also the more versatile of the two, rated from 10K up through the marathon, where the Alphafly is really a half-and-full specialist whose bulkier pod construction feels unwieldy if you're not holding race pace. Fit is a genuine deciding factor: the Alphafly's AtomKnit upper sits on a wider, more accommodating base, while the Adios Pro 4 runs narrow and snug on a tighter racing platform. Both share the same compromises — low stability that feels tippy at jog speeds, and soft foams with thin race outsoles that wear quickly, so neither is a shoe for daily mileage.
