With their cloud names, the Asics Gel Nimbus and Gel Cumulus are easy to mix up. The rule is simple though: the Nimbus 28 remains the most cushioned and most protective model in the lineup, while the Cumulus 28 plays the daily training card, lighter and more affordable.
The gap has narrowed though. Asics has pumped up the cushioning of both series with each version: you now get 43.5 mm under the Nimbus’ heel versus 38.5 mm for the Cumulus, a taller midsole, though not in a different league.
The drop is 8 mm on both models (Asics lowered it a few years ago to match the trends).
The real difference comes down to the foam and the cushioning height. The Nimbus 28 uses FF Blast+, while the Cumulus 28 moves to the new FF Blast Max. On the road, the Nimbus offers a nicely balanced feel between plush and firm, with impressive comfort from the moment you slip it on. The Cumulus is balanced too, but leans a bit more firm, with a more direct ground contact.
On energy return, the result is moderate. These are training shoes that stay fairly conventional and leave the responsiveness to the Blast lineup (like the Novablast 6).
On the upper side, the Nimbus 28 goes for an engineered mesh with the precise fit and comfort that built its reputation. The Cumulus adopts a simpler construction, breathable and comfortable, true to the series.
In use, both cover the same ground: daily training, from easy runs to long runs, up to a moderate-pace marathon. The Nimbus 28 does more on recovery thanks to its maximal cushioning and its wide, stable base. The Cumulus 28 remains the reliable, versatile training partner, a step below on protection but a bit lighter when you pick up the pace.
Nimbus 28 or Cumulus 28: Which Should You Choose?
If you want maximum comfort for all your training and even a marathon, the Nimbus 28 is the brand’s comfort benchmark. But that premium feel comes at a price: expect to pay about $25 more.
For most runners, the Cumulus 28 is plenty: simpler, lighter and less expensive, it also does a great job in training. If you are just starting out, start with the Cumulus, reliable and more affordable. You can move up to the Nimbus later if you need more cushioning.
