Nike Alphafly 4 Features
Nike claims to have rebuilt the Alphafly 4 as a complete racing system, where each component works together to help runners maintain speed and efficiency as fatigue sets in during a marathon. Among the new additions is an Atomknit upper that is said to offer a more precise fit. It also gets zoned midfoot cables, an integrated heel unit, and a moulded sock liner for added foot security.
The biggest change, meanwhile, is the new ZoomX LT foam. Nike says the foam is up to 17 percent lighter than standard ZoomX and delivers 8 percent more energy return. It is layered with ZoomX above and below the carbon-fibre Flyplate to provide cushioning, bounce and a smoother transition through each stride.
The carbon-fibre Flyplate retains the Alphafly’s propulsive scoop and is designed to balance stability with forward propulsion. As per Nike, it works with the surrounding foam to create what it describes as a smooth rolling sensation. On the other hand, the dual forefoot Air Zoom units provide additional responsiveness.
The shoe uses a Fast Shot outsole for traction and grip. Nike says these changes make the Alphafly 4 the lightest and most responsive Alphafly yet. It is also claimed to offer 10 percent more energy return than the previous generation.
The development of the shoe is claimed to have involved feedback from athletes across multiple Alphafly generations, along with learnings from Nike’s Project Dreamweaver, women’s trials, and testing involving distance runners with different abilities and running intensities.
The Alphafly 4 is aimed at marathon runners, from elite athletes to recreational runners.
