Features Comparison


The Nimbus 26 features a breathable mesh upper with synthetic overlays, while the Cumulus 25 uses a seamless engineered mesh upper. Both have padded tongues and collars for comfort.

The Nimbus 26’s AHAR+ rubber outsole provides excellent grip and durability. The Cumulus 25 also utilizes AHAR rubber in high-wear areas for traction and longevity.

Both shoes contain ASICS’ FF BLASTTM PLUS ECO cushioning in the midsole, made from plant-based ECO materials to reduce weight while still providing responsive cushioning.

The Nimbus 26 has a slightly thicker midsole stack height for more cushioning. The insoles are removable in both models for the option to use custom orthotics.


The outsoles on both the Nimbus 26 and Cumulus 25 are constructed with durable ASICS High Abrasion Rubber (AHAR), providing exceptional longevity even after many miles.

The Nimbus 26 also incorporates ASICS proprietary rubber compound AHAR+ for improved durability in critical high-wear areas. Testers found the outsoles showed minimal wear even after well over 500 miles.

The engineered mesh uppers are also constructed to last over repeated wears without tearing or excessive breakdown.

Overall, the Nimbus 26 may have a slight edge in longevity thanks to the enhanced AHAR+ rubber and thicker midsole foam. However, both models are built to last for serious mileage by runners of all levels.

For runners seeking a durable daily trainer that can stand up to the rigors of training, the Nimbus 26 and Cumulus 25 represent two excellent and resilient options.


The Nimbus 26 runs true to size for most runners, with a wider fit through the midfoot and toebox that accommodates wider feet. The mesh upper and padded collar provide a secure and comfortable fit.

Meanwhile, the Cumulus 25 has a seamless upper that conforms closely to your foot for a sock-like fit. The roomy toebox also allows toes to splay naturally. Sizing is consistent overall in both models.

One key difference is the Cumulus 25 has a softer engineered mesh that molds more closely to foot shape compared to the Nimbus 26’s sturdier mesh. However, the Nimbus 26 may work better for runners needing a little more structure around the midfoot.

Both shoes are great options for runners with medium to wide foot types looking for an accommodating daily trainer.


The Nimbus 26 and Cumulus 25 are neutral cushioned shoes not designed for severe overpronators. However, the Nimbus 26 incorporates guidance line technology – a vertical flex groove along the midsole – to provide gentle stability and support for mild overpronators. Reviewers noted it keeps the foot aligned properly through the gait cycle.

The Cumulus 25 does not have quite as much built-in stability technology, though testers said the dual-layer midsole still provides good shock absorption without too much compression. Whether you need light support for low arches or prefer a flexible neutral ride, the Nimbus 26 and Cumulus 25 have just enough cushioning without excessive motion control.

For those with completely neutral gaits, the Cumulus 25 may allow for more natural foot movement. The Nimbus 26 gives light guidance without impeding a neutral runner’s stride.


Cushioning is a strength of both the Nimbus and Cumulus lines. The Nimbus 26 features a full-length FF BLASTTM PLUS ECO midsole made from organic biomass foam to deliver responsive cushioning and bounce. Reviewers found it provides a soft underfoot feel without being overly plush.

Meanwhile, the Cumulus 25 incorporates the same FF BLASTTM PLUS ECO foam but in a slightly lower profile midsole. Testers reported it has a firmer feel than the Nimbus 26 with more road feedback. While the Cumulus 25 is by no means harsh, the Nimbus 26 has more overall softness for high mileage days.

However, some runners appreciated the springier, more energetic ride of the Cumulus 25 for quicker paces. For runners seeking maximum softness, the Nimbus 26 is the winner, while the Cumulus 25 balances cushioning with ground feel. Both provide excellent shock absorption from heel strike to toe-off.

Value for Money

At a $160 retail price, the Nimbus 26 doesn’t come cheap but delivers features commensurate with the price. The ample cushioning, support, durability, and well-constructed upper make it a worthwhile investment for serious runners.

The Cumulus 25 costs $20 less with a $140 price tag. For that lower price, you still get a durable outsole, breathable upper, and responsive midsole. The value comes down to your needs – the Nimbus 26 makes sense for runners who prioritize plush cushioning and mild support features. However, the Cumulus 25 is arguably a better bargain for runners satisfied with moderate cushioning from a versatile yet affordable daily trainer.

For newer runners or those on tighter budgets, the $140 Cumulus 25 provides great value. But those needing extra comfort for high mileage can justify spending more for the acclaimed Nimbus cushioning system.

Performance Comparison:


The Nimbus 26 and Cumulus 25 both make supportive walking shoes, but the Nimbus 26’s extra midsole cushioning gives it an advantage for all-day wear. Testers found the soft FF BLASTTM PLUS foam absorbs shock to reduce foot fatigue over long distances.

The Cumulus 25 is also comfortable for walking with its responsive midsole, though some felt it didn’t dampen impacts quite as much as the Nimbus. Both provide good traction for varied walking surfaces. For the most step-in comfort while racking up fitness tracker stats or taking a stroll, the well-cushioned Nimbus 26 is the top choice.


Experienced runners found both models provide a smooth and consistent ride for easy mileage. The additional midsole foam of the Nimbus makes it better suited to long, slow runs when you want plenty of cushion for the miles. And the stability features prevent excess movement so you can focus on your pace.

For tempo runs or speedwork, the Cumulus 25 gets the nod with its snappier responsiveness when you turn up the pace. The flexible ride lets you corner and transition quickly during fast training sessions. While versatile enough for a wide range of runs, the Cumulus 25 favors faster days while the Nimbus 26 prioritizes comfort over speed.

Plantar Fasciitis

The ample cushioning and stability features of the Nimbus 26 make it the better choice of the two for runners with plantar fasciitis. The soft midsole foam absorbs shock and reduces pressure on the heels and arches with each step.

The arch support and guidance line technology also enhance gait mechanics to prevent the foot from rolling inward excessively to irritate the plantar fascia. While also a cushioned neutral trainer, testers found the Cumulus 25 did not relieve plantar fasciitis discomfort quite as well.

For runners needing extra midsole softness and stability to manage heel and arch pain, the Nimbus 26 stands out.

Standing All Day

For those whose jobs require being on their feet for prolonged periods, both models cushion and support feet but the Nimbus 26 provides superior comfort. The plush foam conforms to the contours of the foot without compacting over time.

Testers raved about the Nimbus 26’s ability to reduce fatigue and pain even after all-day shifts in service industry jobs. While also appropriate for standing, the Cumulus 25 lacks the same level of plushness to prevent discomfort when stationary for hours. Healthcare professionals, retail employees, and service staff praise the Nimbus 26 for keeping feet content regardless of how long they’re standing.

Final Verdict:

In summary, the Nimbus 26 and Cumulus 25 are both well-made neutral trainers suitable as daily runners for a wide range of runners. The main differences come down to cushioning and flexibility.

The Nimbus 26 provides a softer, more supportive ride with mild stability features ideal for comfort over long miles, making it the better choice for walking, plantar fasciitis, and standing all day.

Meanwhile, the Cumulus 25 has firmer but livelier cushioning and greater flexibility in the forefoot, favoring faster-paced runs over high mileage. It offers an agile, smooth, and consistent performance for neutral runners.

At $20 less, the Cumulus 25 also provides great value without compromising on quality materials and construction. For runners seeking plush comfort no matter where the miles take them, the Nimbus 26 is the winner. But if you prioritize ground feedback for faster days, the Cumulus 25 gets the nod as an affordable go-to trainer.
