Asics Gel Kayano 31

Asics Gel Kayano 31 review: what runners say

Fit

True to size per most sources; the toe box runs slightly narrow on some foot shapes, but not enough to size up. Runners wanting more room can go half a size up.

Feel

High cushioning and a stable platform thanks to FF Blast+ Eco and the 4D Guidance system; the response isn't that of a reactive daily trainer, but the transition is smooth and the ride is consistent at easy paces.

Durability

Hybrid AsicsGrip outsole shows minimal wear after 150 km of testing; the 600 km mark is considered achievable without structural issues, with further mileage depending on individual runner characteristics.

Best for

Built for runners with mild to moderate overpronation seeking adaptive stability over long distances and easy-pace daily training. Not suited for runners prioritizing speed or lightweight feel.

Weak points

The overall volume of the shoe feels bulky at faster paces. Upper breathability, while improved over the version 30, remains insufficient in hot and humid conditions.
