The Asics Gel Cumulus 23 is a traditional running shoe for daily training. With this new model, the Japanese brand has succeeded in making significant changes while retaining the DNA of the shoe.

The sole still displays a moderate thickness with 23 mm under the heel (22 mm for women) and a drop of 10 mm (against 9 mm previously). However, testers note that the cushioning continues to offer ideal shock absorption thanks to the FlyteFoam and the GEL unit. In addition, the 3D Space Construction design (inherited from the Lite line) makes an appearance to give a smoother ride (and, by the way, smoother for women). The result is convincing according to the testers. Thus, the Cumulus offers a pleasant race, not really dynamic but not soft either. The sole density is moderate, so it’s a good option for runners who like soles that aren’t too firm or too soft (or for beginners who aren’t quite sure what their preferences are yet).

The upper is simple and efficient with a relatively thick technical mesh that provides precise and comfortable support for the foot. Finally, the outsole is, as on most Asics models, generously provided with rubber for good durability.

In summary, the Asics Gel Nimbus 23 will continue to delight fans of the line. It is well suited for daily training at slow or moderate pace. Its main drawback is the weight with 289 g (H), which is high compared to the moderate thickness of the sole.



  • The resistant rubber ensures impeccable traction on the asphalt and protects the shoe from wear. It is harder under the heel and softer under the forefoot for optimal comfort.


  • The midsole features FlyteFoam : an energetic and lightweight foam developed by Asics that offers excellent energy return. This midsole technology is made with a unique elastomer compound that guarantees excellent responsiveness throughout the run, even when the shoe wears out. It also uses strong organic fibers which should reduce the chances of the sole collapsing as can be the case with softer foams.
  • 3D Space Construction : a structure with geometric shapes in the midsole to improve stride stability. Also, the setup is different for women, with softer cushioning.
  • Finally, GEL is a silicone-based gel cushioning piece that provides effective shock dispersion.

  • The technical mesh provides effective support for the foot and facilitates good ventilation in order to offer a pleasant feeling of freshness when you go faster.

Frequently Asked Questions (FAQs)

How big is the Asics Gel Cumulus 23?

Athletes who have tried the shoe confirm that it fits just right. So you can choose your normal size for sports shoes. However, if this is your first Asics model, a visit to the store is advisable to be sure to choose the most suitable size.

Is the Gel Cumulus 23 suitable for pronator athletes?

Yes, this model is a shoe for neutral gait (also called universal). Thus, it is designed to suit all runners regardless of their stride. It therefore does not display any particular help in stabilizing the stride and avoiding pronation or supination. There are shoes specifically designed to reduce overpronation but, without scientific evidence, we don’t recommend them, unless of course you find them comfortable.

Is this model for the road suitable for heavy athletes (85 kg or more)?

Yes, this model should be suitable whatever your morphology. Indeed, although it is often recommended to run with well cushioned shoes if one is heavy, there is in fact little or no evidence that this can reduce the risk of injury. Only one scientific research study to date has investigated the subject. According to this, minimalist shoes (thus with a sole less than 15 mm thick) could increase the risk of injury for athletes over 71 kg. The Gel Cumulus 23 has a moderately thick sole and should therefore be suitable for your weight whatever it is.

Is it possible to run a marathon or a half marathon with these shoes?

This Asics road shoe is quite suitable for different types of training and distances. You can therefore wear it during your daily workouts, of any type. As for the marathon, it mainly depends on your preferences. Best to incorporate it into your training to ensure there is no discomfort or pain on your long rides.

Comparisons – Asics Gel Cumulus 23 vs:

Nike Air Zoom Pegasus 37

The Pegasus offers a thicker sole even if the feeling is firmer according to the testers. With 20 g less, it is clearly lighter than the Nimbus. However, the outsole of the latter has more rubber, which can make it sturdier. The rest is really a matter of personal preference.
