ASICS Men's Gel-Kayano 31 Running Shoes
The Gel-Kayano 31 continues ASICS's long-running stability platform with an updated midsole and an overhauled guidance system. The 4D Guidance System replaces the prior iteration's single-plane approach with multi-directional support that adapts to your individual gait cycle rather than applying a fixed correction. The FF BLAST PLUS ECO midsole delivers lightweight cushioning with better energy return than standard EVA foam — the ride is cushioned without the soft feel that undermines ground feedback on longer runs. Rearfoot GEL technology absorbs impact at heel strike, smoothing the transition from landing into the gait cycle. The engineered mesh upper uses a thinner construction than previous Kayano versions, reducing weight without giving up structure at the midfoot. The Kayano 31 is heavier than neutral daily trainers — that's the trade-off for the stability infrastructure. For distance runners who need support across five-plus training days per week, the Kayano 31 handles the mileage.

What we like
- + 4D Guidance System applies multi-directional stability that adapts to individual gait rather than applying a fixed correction
- + FF BLAST PLUS ECO midsole provides cushioned energy return without the soft, unstable feel of memory foam alternatives
- + Rearfoot GEL technology smooths heel-strike transitions — consistent across different landing patterns
- + Lighter and less built-up than prior Kayano generations while maintaining the stability infrastructure
Watch out for
- - Heavier than neutral daily trainers — not suited for tempo runs or race day
- - Support level targets moderate overpronation; significant stability needs may require a more structured shoe
Our verdict
Best ASICS stability trainer for distance runners. The updated 4D Guidance System and FF BLAST PLUS cushioning make the Kayano 31 lighter and more responsive than prior versions without reducing the support that defines the line.
