ASICS Gel-Kayano 31 Review (2026): The Stability Benchmark
The Gel-Kayano has been the reference stability shoe for three decades, and the 31 is the modern version of that promise: no hard medial post, but a 4D Guidance System that steers overpronation with geometry — a wider base, guidance-line outsole, and adaptive foam — instead of fighting it with a block of firm plastic.

How the stability works
If your ankles roll inward as you land — overpronation — the Kayano 31 is built for you. The 4D Guidance System controls that motion through structure rather than stiffness: testers consistently describe it as stability you feel only when you need it. The 4/5 stiffness heel counter anchors the rearfoot, and the wide platform under a 38mm stack resists tipping. Runners unsure whether they overpronate can start with our overpronation shoe guide, which explains the wet-foot test and wear-pattern check.
Cushioning
Stability shoes used to be punishingly firm. The Kayano 31 is not: FF Blast+ with a rearfoot Gel unit measures 28 HC — a balanced medium — and comfort scores 91/100. Energy return of 61% is respectable for a shoe whose job is control. The ride is smooth and structured, best at easy to steady paces.
Fit and sizing
Runs true to size. Like the Nimbus, the Kayano comes in B, D, and 2E widths with a 94mm toebox and an orthotic-friendly removable OrthoLite X-55 insole — relevant, because many overpronators run with custom orthotics. Fit scores 90/100.
Weight and durability
At 298g the Kayano 31 is the heaviest shoe in this review cycle, which is the honest cost of a full stability chassis. Durability is a strength — 87/100, with the AHAR+ outsole among the hardest-wearing in running. For a $160 shoe (value 79/100), it earns its keep in lifespan.
Who should buy the ASICS Gel-Kayano 31?
Best for: Overpronators, heavier runners, long easy miles, and runners managing plantar fasciitis who also need pronation control.
Not ideal for: Neutral runners — if your gait doesn't need correcting, the Gel-Nimbus 26 gives you the same comfort formula without the guidance structure, and the Brooks Ghost 16 is the lighter neutral all-rounder. It is also not a speed-work shoe.
Verdict
The ASICS Gel-Kayano 31 scores 88/100 in SoleHunt's data-driven evaluation — the top-scoring stability shoe in our database. If a physio, a wear pattern, or painful shins have pointed you toward a stability trainer, this is the one to measure the rest against.
