ASICS Gel-Nimbus 26 vs. Gel-Kayano 31: neutral or supportive?

Gel-Nimbus vs. Gel-Kayano: the one difference that counts

People who lay the two models side by side are usually looking for the wrong difference. It is not about more or less cushioning, not about more or less expensive and not about beginners or advanced runners. It is about exactly one characteristic, and it is called support.

• The ASICS Gel-Nimbus 26 is a neutral maximum cushioning shoe. It cushions the impact but does not guide the foot. What your foot does when rolling is left up to you.
• The ASICS Gel-Kayano 31 is a stability shoe. It is built so that the foot tilts inwards less when rolling, and it uses a deliberately asymmetric midsole for this.

Everything else, that is foam, upper, price level and target group, is close together on both. Once you have worked out whether you need support, the buying decision is practically made. The basics are covered in Neutral shoe or stability shoe?.

The manufacturer data side by side

Both shoes sit at the top of their respective line at ASICS and share the same guide price. The following values are manufacturer figures for men's shoes in roughly size 42. They say more about the character of the two shoes than any description.

• ASICS Gel-Nimbus 26: neutral, maximum soft cushioning, FF Blast+ Eco with PureGEL, 8 mm drop, approx. 300 g, also available in 2E and 4E widths. Guide price (RRP-based) around €200.
• ASICS Gel-Kayano 31: support shoe, stable cushioning, FF Blast+ with 4D Guidance System, 10 mm drop, approx. 300 g, also available in 2E and 4E. Guide price (RRP orientation) around €200.

Two things stand out. First, the weight is practically identical, so the Kayano is not the heavier shoe, as the cliché about support shoes would suggest. Second, the two differ by 2 mm of drop: at 10 mm the Kayano sits slightly higher, which takes a little load off the calf and Achilles tendon and fits the already calmer design. What these millimetres mean in practice is explained in Drop explained simply.

PureGEL and 4D Guidance: what is behind the names

ASICS gives every line its own technology names, and they confuse more than they explain. At their core, both shoes use the same foam, FF Blast+ or its Eco variant. The difference lies in what ASICS builds in on top.

• PureGEL in the Gel-Nimbus 26 is the softer, lighter version of the classic gel insert in the heel. According to the manufacturer, it aims for a gentler landing, not for more guidance.
• The 4D Guidance System in the Gel-Kayano 31 describes a midsole that is built differently on the inside than on the outside. It replaces the hard pronation wedge of earlier generations with a softer, wider construction.
• The simpler variant of the same principle is called the 3D Guidance System and is found in the cheaper ASICS GT-1000 13.

The context matters: modern support shoes no longer actively push the foot into a position but limit movement more gently than they used to. This applies to ASICS just as much as to Brooks GuideRails or the Hoka H-Frame. A Kayano therefore does not feel like a corset but like a shoe that sits more steadily under the foot.

Do you need a support shoe at all?

This question decides the comparison, and you can narrow it down roughly at home. Only a gait analysis in a specialist shop gives a reliable verdict, but you can get two pointers without an appointment.

• Look at the soles of your old running shoes: if the outer edge of the heel is worn and the wear then runs clearly towards the inner side of the forefoot, this points to pronounced pronation.
• Look at your heel from behind while standing: if the Achilles tendon visibly tilts inwards when you stand, that is another indication.

If neither applies and you run without complaints in neutral shoes, you do not need a Kayano. In that case the Nimbus is the more suitable and more versatile shoe. This is covered in more detail in Running shoes for overpronation. And an honest caveat belongs here: a support shoe is not a cure. If you are in pain, have the cause checked by a doctor instead of trying to solve it through shoe choice. What a shoe can and cannot do here is put in context by Running shoes for knee pain.

The cheaper siblings: Cumulus and GT-1000

ASICS builds both concepts in a second, much cheaper price class. For many runners these models are the more sensible choice, because they serve the same purpose and cost almost half as much. The difference lies mainly in the amount of foam and in the upper's features.

• ASICS Gel-Cumulus 26: the neutral everyday shoe below the Nimbus. FF Blast+ Eco, 8 mm drop, approx. 270 g, also in 2E width. Guide price around €150.
• ASICS GT-1000 13: the support shoe below the Kayano. FF Blast+ with 3D Guidance System, 8 mm drop, approx. 272 g, also in 2E and 4E. Guide price around €120.

Both are around 30 g lighter than the premium models because there is less material under the foot. If you run moderate weekly distances and do not plan very long sessions, you lose little. If, on the other hand, you put a lot of weight on the shoe or are regularly out for more than an hour, you benefit more from the thicker build of the top models. Suitable candidates are collected in Best running shoes for long runs.

If neither fits: the other ASICS lines

Nimbus and Kayano cover cushioned everyday running, but not the whole range. Four further models handle tasks for which both are too heavy or too expensive.

• ASICS Gel-Kinsei Max: neutral, built even thicker than the Nimbus, 8 mm drop, approx. 300 g, only in standard width. Guide price around €220.
• ASICS Superblast 2: neutral, but responsive rather than soft, 8 mm drop, approx. 250 g. The shoe for anyone who wants plenty of cushioning without sinking into the foam.
• ASICS Magic Speed 4: FF Blast+ with carbon plate, 7 mm drop, approx. 230 g. For speed sessions and races, not for daily easy runs.
• ASICS Gel-Excite 10 and ASICS Patriot 14: neutral entry-level models at approx. 250 g with guide prices of around €80 and €65 respectively. Solid for the first few weeks, without the ambition of the major lines.

A note that regularly causes confusion: the ASICS Gel-Kayano 14 is no longer a running shoe today but a lifestyle model. It carries the same name but is a reissue of an old silhouette for everyday wear. If you are looking for a support shoe, go for the Kayano 31, not the Kayano 14.

How Nimbus and Kayano compare with other brands

Both models have a counterpart at every other major brand. The comparison helps especially when a model is not currently available in your size or when the fit is wrong.

Direct competitors to the Kayano 31 (support shoes):

• Brooks Adrenaline GTS 23: GuideRails, 12 mm drop, approx. 289 g, in 2E and 4E. The most classic rival, with the highest drop in the field.
• Hoka Arahi 8: H-Frame, 8 mm drop, approx. 277 g. The lightest of the support shoes mentioned.
• Saucony Guide 17: CenterPath, 6 mm drop, approx. 272 g. The flattest variant, noticeably different from the Kayano.
• Nike Structure 25: Cushlon with Zoom Air, 10 mm drop, approx. 300 g. Closest to the Kayano in terms of geometry.
• Mizuno Wave Inspire 20: Enerzy with Wave plate, 12 mm drop, approx. 295 g.
• Saucony Hurricane 24: PWRRUN PB, 8 mm drop, approx. 300 g. The most cushioned support shoe in the line-up.
• Brooks Beast GTS 24: 12 mm drop, approx. 340 g, in 2E and 4E. Built considerably more solidly, intended for higher body weight.

Direct competitors to the Nimbus 26 (neutral max-cushion shoes):

• Brooks Glycerin 21: DNA Loft v3 with nitrogen, 10 mm drop, approx. 289 g, also in 2E.
• Hoka Bondi 8: EVA maximum stack, 4 mm drop, approx. 312 g. The flattest and heaviest alternative.
• Brooks Ghost 16: not a max-cushion shoe, but the neutral all-rounder one step below, 12 mm drop, approx. 278 g.

How the two cushioning brands Hoka and Brooks differ from each other is covered in Hoka vs. Brooks. If you are heavier and therefore pay particular attention to durability and stability, you will find suitable models in Running shoes for heavier runners.

Fit, width and size

In terms of fit, the two models are no different according to the manufacturer. Both run true to size, and both are also available in 2E and 4E widths. That is a real advantage over many competitors, where extra widths apply only to individual models.

When choosing a size, the thumb-width rule applies to running shoes: about one centimetre of space should remain in front of the longest toe, because the foot slides forward when running and swells over the course of a session. Many runners therefore end up half a size above their everyday size. It is best to try shoes on in the evening and with the socks you will actually run in. The whole procedure is in Running shoes: finding the right size, and if you generally need more room in the forefoot, you will find models in Running shoes for wide feet.

Decision aid: which one suits you?

Finally, the short version, sorted by the situation you are in right now. It does not replace trying them on, but it narrows the choice down considerably.

• You run neutral and want maximum soft cushioning: Gel-Nimbus 26.
• Your foot clearly rolls inwards as it rolls through: Gel-Kayano 31.
• You are unsure and have run without complaints so far: stay neutral, so the Nimbus or the cheaper Gel-Cumulus 26.
• Around €200 is too much for you: Gel-Cumulus 26 instead of the Nimbus, GT-1000 13 instead of the Kayano.
• You want cushioning, but not a soft shoe: Superblast 2.
• You also need width: both top models come in 2E and 4E, as does the GT-1000 13.
• You are looking for your first running shoe: Gel-Excite 10 or Patriot 14, plus Best running shoes for beginners.

If you want to lay both models side by side, the comparison helps. The shoe finder instead sorts by use, support and cushioning, and the complete selection is under Running shoes. How long your new pair lasts and how to tell when to replace it is covered in Replacing running shoes: when?.
