Our Verdict
Nike Alphafly 3
ASICS METASPEED SKY PARIS
The Nike Alphafly 3 and the ASICS METASPEED SKY PARIS are both top-tier super shoes, but they deliver very different sensations underfoot. The Alphafly 3 is heavier, but it offers a bit more overall cushioning, making it a better option for runners who value long-distance protection and impact absorption. That said, it still features some firmness in the forefoot, thanks to its distinctive Air Pods. In contrast, the ASICS is lighter, with a more direct and snappy ride that favors runners who prefer ground contact and sharp transitions, making it more specialized for shorter races.
