Since its launch, the Alphafly has established itself as an iconic Nike shoe for marathon competition. The brand is built around a combination of foam, a carbon plate and Air Zoom units. With the fourth generation, the company keeps this architecture while seeking to make the platform more accessible and easier to exploit by a wider range of runners.
The Alphafly 4 also fits into a history of marathon benchmarks. The text recalls that in 2019, Eliud Kipchoge had carried out a non-sanctioned attempt with a prototype, becoming the first man to run under the two-hour barrier for the marathon. More recently, it refers to April, when two men ran an official marathon in under two hours.
Nike presents the Alphafly 4 as a shoe designed to manage fatigue more effectively as the effort goes on. The brand stresses efficiency and maintaining pace when fatigue sets in, with a stated focus on the second half of the marathon. To achieve this, several components are said to have been revised.
Among the new features, the brand announces 10% additional energy return and reduced weight. The evolution of the ZoomX LT foam is also detailed: up to 17% lighter than the standard ZoomX, with 8% additional energy return. The text also mentions a Fast Shot outsole for grip while limiting weight, as well as two Air Zoom units in the forefoot.
For sales, the Alphafly 4 arrives in two stages. The text indicates a limited-quantity offer from 17 September on nike.com, followed by broader availability on 29 October on Nike’s website and in certain retail locations. The stated price is €279.99, with a stack height of 39 mm at the heel and 31 mm in the forefoot, for an 8 mm drop (M10).
