ASICS GEL-Kayano 25 Review

The new ASICS GEL-Kayano 25! With some significant midsole, outsole, and upper changes, the Kayano 25 is all-new and has a slightly updated ride to go with a little more generous fit.

ASICS has significantly re-designed the Kayano for the 25th version, updating the midsole, outsole, and upper – and has firmed up the ride a little bit as compared to the pervious Kayanos. Here are the main changes:

ASICS Kayano 25 vs 24

  • ASICS has changed the midsole to use a couple new variations of their FlyteFoam technology – creating a little lower, firmer ride
  • The outsole looks to be a little more chunky, adding some traction (although it’s unlikely anyone found the Kayano 24 lacking in traction)
  • The upper has been redesigned to be a more flexible, forgiving mesh and the overall fit of the shoe is a little roomier
  • Stability remains unchanged, with the Kayano providing a nice stable platform and upper that works well for runners who need some amount of guidance
  • The new versions of FlyteFoam that ASICS has used in the Kayano 25 has caused the weight to increase a bit, but because that same foam creates a more performance-feeling ride, you’re probably not going to feel a difference on-foot


The new Kayano 25 remains a pretty standard fit, with the more flexible mesh upper possibly providing a little more room for wider feet. It seems a little wider than the previous Kayano and significantly more generous than the Kayano 23, but not enough that it would change sizing or appropriateness for anyone. The toe box is a little roomier than the 24.


ASICS continues the trend that many shoe manufacturers have been on recently, making the new GEL-Kayano 25 a little more performance-feeling. It’s still on the softer side of the guidance realm, but no longer does it provide such a consistent level of perceived cushion as it might have in the past. It does continue to be a well-cushioned trainer that has a significant amount of guidance to prevent pronation.


Even with the complete midsole change, the GEL-Kayano 25 remains a good candidate for runners needing & wanting a mild to medium level of guidance to offset any pronation.


ASICS GEL Kayano vs GT 2000

ASICS has designed the Kayano to be both more cushioned and supportive than the 2000. In their current versions, each shoe feels and functions consistent to those design specifications. The 2000 is a little firmer and provides a little less support, but there is an increasing amount of similarity between the shoes as the Kayano has become more firm. The 2000 is lighter, and it feels lighter thanks to the more performance-feel and the lower weight.

ASICS GEL Kayano vs Nimbus

Each is designed to be ASICS’ maximum amount of perceived cushion, and in previous generations they have both been consistent in providing that cushion. Both have recently become a little firmer, however, and we’ve seen that consistency drop a little with their recent updates. They have very different levels of support, so the Nimbus would be appropriate for neutral runners while the Kayano functions well for runners who pronate.

ASICS GEL Kayano vs Brooks Adrenaline

Both the Brooks Adrenaline and the Kayano have been updated to provide a flexible, forgiving mesh upper. While traditionally the Kayano has felt softer than the Adrenaline, in their current versions (Kayano 25 vs Adrenaline 18), they feel pretty similar – so each runner might feel like one is softer, but it doesn’t seem to be consistent as to which feels softer. The Kayano has a little more room in the toebox. The Kayano has more guidance than the Adrenaline, but both provide a moderate of guidance which make them appropriate for runners and walkers who have a moderate amount of pronation and feel more stable with some guidance for that pronation. The Adrenaline is considerably lighter than the Kayano, and feels it on-foot.

ASICS GEL Kayano vs Saucony Guide ISO

In their current versions, the shoes have a pretty different feel. The Kayano has an overall softer feel, both in the upper and in terms of midsole/ride . The Guide feels lower and there’s more of a cradling feel of the midsole whereas the Kayano is much higher and there’s more of a platform feel. The Guide has more room in the toebox and is a little wider overall – to the extent that it feels a little sloppy on narrower feet compared to the Kayano.¬† The Guide is lighter, and thanks to being both lower and a little firmer actually feels lighter on your foot.

ASICS GEL Kayano vs Mizuno Wave Inspire:

In their newest versions (Kayano 25 vs Inspire 14), the Kayano still feels softer than the Inspire. The Inspire is a little lower and has a more performance-based feel. The Kayano is narrower and has a slightly smaller toebox. The upper of the Kayano is much more flexible, with fewer overlays and and a much more comfortable mesh upper. In terms of guidance/stability, the Kayano is still going to provide more stability than the Inspire (with the new Inspire 14 increasing the amount of support over the Inspire 13), but both are appropriate for runners and walkers who need some guidance. The weights are about the same, and each feels about the same on-foot.
