Our Verdict

ASICS GEL-KAYANO 31

ASICS GEL-NIMBUS 28

The ASICS GEL-KAYANO 31 and the ASICS GEL-NIMBUS 28 sit in two clearly different categories despite sharing a premium feel. The KAYANO 31 is heavier and built as a dedicated stability shoe, with a lower drop, a more structured platform, and guidance elements that make it noticeably more stable and controlled, especially for runners who need support over long mileage. The NIMBUS 28, on the other hand, is a max-cushioned neutral trainer that prioritizes comfort and impact absorption, offering a softer and more forgiving ride but with less inherent stability. In short, the KAYANO is about control and support, while the NIMBUS is about cushioning and relaxed comfort.
