Asics Cumulus vs Nimbus – Why one may not be right for you

Asics Gel Cumulus and Asics Gel Nimbus are both popular running shoes. Both offer neutral support and are designed for road running. The versions that I tested were the 24th version and the latest 25th versions are now available. So, head to head Asics Cumulus vs Nimbus which should you buy?

I’ve run in both shoes and been a long term runner using various Asics models. From many years of using Asics road running shoes there are some real differences I found between the shoes. After running in both find out which I now use day to day. And why I stopped using one.

The diagram shows both pairs of my running shoes side by side. The black/white shoe (left) is the Asics Gel Nimbus 24. The black/blue shoe (right) is the Asics Gel Cumulus 24. As you can see both are very similar aside from colouring. Read on for more details on the differences.

Asics Gel Cumulus 24 Review

The Asics Gel Cumulus 24 is a neutral running shoe that offers good cushioning and support. It is designed for runners who have a normal arch or slightly flat feet. This means you don’t get any support for pro-nation in your run. The Cumulus features Asics’ flytefoam GEL cushioning technology. This helps absorb shock and reduce impact during the landing phase of the footstrike. It also has a comfortable and breathable upper and a durable outsole that provides good traction.

The Asics Cumulus targets road runners looking for a comfortable shoe. Relatively heavy these are shoes for mid to long distance road runners.

Asics Gel Nimbus 24 Review

The Asics Gel Nimbus 24, has been Asics premium neutral running shoe. Priced higher than the Asics Cumulus this has been their flagship for a number of years. Now superseded by the Asics MetaSpeed range. A direct response to Nike and their Air Zoom Alphafly Next%. The Nimbus is designed for runners who want maximum cushioning and support.

It features a knitted upper that is made of high-quality materials, such as jacquard mesh that cocoons the foot. The Nimbus also has a full-length FlyteFoam midsole that provides excellent shock absorption and energy return. The outsole of the Nimbus is made of durable rubber that offers good traction on a variety of surfaces.

The Asics Nimbus also targets road runners looking for a comfortable shoe. Weighing similar to the Cumulus being relatively heavy these are shoes for mid to long distance road runners.

Asics Cumulus vs Asics Nimbus Key Differences

Asics Gel Cumulus and Asics Nimbus Gel are both popular running shoes from Asics. A reliable supplier to millions of runners worldwide. There are some key differences between the two shoes. The key differences are:

1. Cushioning: Asics Nimbus is designed to provide maximum cushioning, while Asics Cumulus provides a good level of cushioning. The Nimbus features a full-length FlyteFoam Blast midsole, which is Asics’ most advanced cushioning material. The Cumulus, on the other hand, features a combination of Flytefoam and Flytefoam Blast. The Nimbus is positioned as a maximalist cushioning shoe.
2. Weight: Asics Nimbus is slightly heavier than Asics Cumulus. This is very marginal at only 4 grams. So in real terms makes no difference for anyone considering both shoes.
3. Upper: Asics Nimbus has a plush and luxurious upper that is made of high-quality materials, such as jacquard mesh and 3D printed overlays. The Asics Cumulus has a more conventional and breathable upper that is made of engineered mesh. The Nimbus’ upper provides a more snug and supportive fit, while the Cumulus’ upper is more lightweight and breathable.
4. Price: Asics Nimbus is more expensive than Asics Cumulus. The Nimbus is a premium running shoe model that provides maximum cushioning and support, and therefore, it has a higher price point. The Cumulus is a more affordable option for runners who want a comfortable and supportive shoe that offers good cushioning.
5. Fit: Now this is key. The Asics Nimbus was redesigned for the Nimbus 24. This change in design reshaped the front of the shoe. This is coupled with the knitted upper that fits closely around the foot. The result of this is the Asics Nimbus can feel cramped if you have a wide foot. They come in a wide foot fitting and I recommend you consider buying a half size larger than normal sizing. The Asics Cumulus has retained the front foot shape. This means no need to go any larger sizing or consider wide foot fitting for most.

Asics Gel Cumulus 23 vs 24

What is the difference between the Asics Gel Cumulus 23 and 24. The key differences between the two shoes are:

1. Upper: The upper of the Asics Gel Cumulus 24 has been updated with a more breathable mesh material compared to the 23 version. The new upper also has fewer overlays, which results in a more seamless and comfortable fit.
2. Midsole: The midsole of the Asics Gel Cumulus 24 has been updated with Asics’ latest cushioning technology called FlyteFoam Propel. This material is lighter and more responsive compared to the previous version’s midsole. The new midsole also has deeper grooves that allow for a smoother transition from heel to toe.
3. Outsole: The outsole of the Asics Gel Cumulus 24 has a slightly modified pattern compared to the 23 version, which provides better traction and durability. The new outsole also has a more flexible forefoot area, which enhances the shoe’s flexibility and agility.
4. Weight: The Asics Gel Cumulus 24 is slightly lighter than the 23 version, which makes it more suitable for runners who value speed and agility.

Overall, as you would expect the Asics Gel Cumulus 24 has several upgrades compared to its predecessor. The most important for anyone considering both is the improved cushioning with much of the Asics Nimbus cushioning now featuring in the Asics Cumulus. The shoes have been designed for comfort. I switched to the latest Asics Gel Cumulus 24 from having been an Asics Nimbus owner for the past 6 years.

Asics Nimbus 23 vs 24

The Asics Gel Nimbus 23 and 24 are very different shoes to run in as you will feel if you try both pairs on. Here are the key differences between the two:

1. Upper: The upper of the Asics Gel Nimbus 24 has been updated with a new engineered mesh that means they fit tightly around the foot. This uses a lightweight mesh.
2. Midsole: The midsole of the Asics Gel Nimbus 24 has been updated with Asics’ latest cushioning technology called FlyteFoam Blast. This material is lighter, softer, and more responsive compared to the previous version’s midsole. The new midsole also has deeper grooves that allow for a smoother transition from heel to toe.
3. Outsole: The outsole of the Asics Gel Nimbus 24 has been updated with a new rubber compound that provides better traction and durability compared to the 23 version. The new outsole also has a more flexible forefoot area, which enhances the shoe’s flexibility and agility.
4. Weight: The Asics Gel Nimbus 24 is slightly lighter than the 23 version. This is very marginal though so nothing to have any material impact on your performance.
5. Fit: The Asics Gel Nimbus 24 has fundamentally changed the design of the shoe in terms of the footprint. The front of the foot shape has been narrowed which has made a dramatic impact on the fitting. Anyone with a wider foot will struggle to wear the shoes in their normal shoe size.

Overall, the Asics Gel Nimbus 24 has several upgrades compared to its predecessor. This has focused on a new style more breathable and flexible upper. This makes for a snug sock light fit. The cushioning has a more responsive midsole with deeper grooves, and a more durable and flexible outsole. As outlined above, make sure you try the shoes on and run in them. Allow your feet to swell from running and ensure the fit is right.

Which Should you buy?

Ultimately, the choice between Asics Cumulus and Asics Nimbus comes down to personal preference and needs. If you’re looking for a more cushioned and supportive shoe and don’t mind the higher price point, then the Nimbus might be the better choice. However, if you have a wider foot you may find the Nimbus uncomfortable and need to look at bigger sizing. .

The Asics Cumulus is a great option for most runners who want a comfortable and supportive shoe that offers good cushioning. The best shoe for you will depend on your individual needs and shape of your foot. So, it’s important to try on both models and see which one feels better for your feet. Where possible try them in a proper running shop with a treadmill and run in them. Allow your feet to swell from the run and see how they feel.

My choice has been to buy the Asics Gel Cumulus 24. Very comfortable and better fit with plenty of cushioning.
