The Nike Alphafly 4 is almost here, and Nike has changed more than the colorway. Nike announced the Alphafly 4 in September as part of its new race-day lineup with the upcoming Nike Apex and Swooshfly. Nike says the Alphafly 4 will launch during October 2026…anticipated October 29th, 2026. Nike already has the Alphafly 4 listed as “Coming Soon” for $280, which is also $15 less than the Alphafly 3’s original $295 price. When do we ever get a shoe cheaper than the last version? For a carbon-plated marathon shoe in 2026, seeing the price move down rather than up almost feels unusual.

Nike Alphafly 4 FAQ
When does the Nike Alphafly 4 come out?
Nike says October 2026. Running Warehouse currently lists October 29, 2026, as its U.S. order date.
How much does the Nike Alphafly 4 cost?
Nike currently lists the Alphafly 4 at $280.
What foam does the Nike Alphafly 4 use?
The Alphafly 4 introduces Nike ZoomX LT foam, which is lighter than standard ZoomX.
Does the Nike Alphafly 4 have a carbon plate?
Yes. It uses a wider carbon-fiber Flyplate along with two forefoot Air Zoom units.
Is the Nike Alphafly 4 cheaper than the Alphafly 3?
Yes. The Alphafly 4 is currently listed at $280, compared with the Alphafly 3’s $295 original retail price.
What Changed in the Nike Alphafly 4?
The biggest update is ZoomX LT, a new version of Nike’s ZoomX foam. Nike developed the lighter foam for the Alphafly 4 and paired it with more foam above the carbon plate. The goal appears to be keeping the Alphafly highly cushioned while cutting weight and smoothing out the ride.
The carbon Flyplate is also wider than the previous version. The Alphafly has never been the lightest racing shoe, and Nike is clearly keeping the huge foam, carbon plate, and Air Zoom formula while refining how those pieces fit together. The two forefoot Air Zoom units return, although Nike reduced the amount of plastic used around them. Each Air unit also has separate chambers.
Runners who have liked the very distinct Alphafly ride are still getting an Alphafly. Nike has not suddenly turned it into the Vaporfly 4, which is considerably lower and lighter.
The Alphafly 4 Upper Is New Too
Nike replaced the previous upper with a new Atomknit construction. According to current product information, the toe box has increased breathability, while zoned midfoot cables and an integrated heel unit are designed to keep the foot secure.
I am curious about the fit because Nike racing shoes can vary wildly. I found the Nike Streakfly 2 extremely narrow, while the Vaporfly 4 was much easier for me to wear.
Where Does the Alphafly 4 Fit in a Running Shoe Rotation?
The company recently introduced its new “Race-Day System of Speed” with the Apex, Alphafly 4, and Swooshfly. I already wrote about what the Nike Apex could mean for the Vaporfly, because the Vaporfly is noticeably absent from that three-shoe collection.
Nike describes the Alphafly 4 as its option for runners wanting marathon speed, while the Apex arrives in January 2027 for runners chasing the fastest option Nike can build. In other words, the Alphafly is no longer automatically the fanciest or fastest Nike marathon shoe.
That may actually help the Alphafly. At $280, it sits only $10 above the Vaporfly 4, while the Apex will occupy the far more expensive end of Nike racing shoes.
Should You Buy the Nike Alphafly 4?
Carbon-plated running shoes do not perform identically for every runner, something I have written about in my post about being a carbon-plated shoe non-responder. The Alphafly geometry is also far more aggressive than a traditional racing flat. For many, it will feel too bulky.
Still, the $280 price, lighter ZoomX LT foam, wider plate, revised Air Zoom setup, and new upper make the Alphafly 4 a substantial update rather than a color change with a new number attached. With the $350-plus Apex arriving in January, Nike is about to make that decision even more complicated.
