ASICS GEL-Cumulus 25 Review

The running industry was shocked when ASICS drastically upgraded its iconic Gel-Nimbus running shoe for 2023.

Fans of soft yet responsive running shoes will be happy to hear ASICS made some significant upgrades to the Gel-Cumulus too.

Athletes have long praised the ASICS Gel-Cumulus as a perfectly balanced running shoe. It’s well-cushioned, flexible, and breathable, three characteristics many avid runners seek.

The Gel-Cumulus 25 is better than ever for 2023, with significant upgrades to the midsole, upper, and the shoe’s same durable high-abrasion rubber outsole. Our team thoroughly researched, tested, and reviewed the Gel-Cumulus 25 to help you determine if it’s the right running shoe for you.

Featuring ASICS Latest Technology

ASICS GEL-CUMULUS 25 Side View

The Gel-Cumulus 25 features a variety of ASICS latest running shoe technologies. The following are our favorite materials and tech ASICS included in this versatile running shoe.

FF BLAST™ PLUS

ASICS FF BLAST™ PLUS technology is throughout the length of the midsole of the Gel-Cumulus 25, which now sports an increased stack height of 2 mm. The pillow-like cushioning offers a bouncier, more energetic ride with enhanced shock absorption.

PureGEL™

ASICS has long been known for the GEL™ technology featured in its running shoe midsoles. The new-and-improved PureGEL™ technology means even more impact absorption, smooth transitions, and an energetic feel from the first mile to the last.

The combination of FF BLAST™ PLUS and PureGEL™ technologies results in a cloud-like ride that’s surprisingly responsive too.

OrthoLite™ X-30 Sockliner

ASICS’ OrthoLite™ X-30 sock liner is a staff favorite for comfort straight out of the box. You won’t have to wear your new running shoes around the house before your first run because the fit already feels like they’re customized to your feet.

The OrthoLite™ X-30 sock liner, combined with the shoe’s engineered mesh upper, results in optimal breathability and comfort from heel to toe.

AHAR PLUS™ and AHAR™ LO Rubbers

ASICS™ running shoes are known as some of the most durable in the industry, and they have been for decades. The ASICS™ Gel-Cumulus 25 lives up to the brand’s strong reputation with two ultra-durable outsole rubbers.

The Gel-Cumulus 25 features high-abrasion AHAR PLUS™ and AHAR™ LO rubbers strategically placed throughout the outsole for exceptional grip without added weight.

Gel-Cumulus 25 vs. Gel-Cumulus 24

ASICS GEL-CUMULUS 24 AND ASICS GEL-CUMULUS 25 Side by side

The Gel-Cumulus 25 features numerous upgrades over the Gel-Cumulus 24 and previous versions. The most obvious difference runners can see and feel is the new PureGEL™ technology.

PureGEL™ is ASICS’ softest and lightest GEL™ tech yet, and it’s a welcome addition to the Cumulus. Aesthetically, our reviewers were thankful ASICS™ eliminated the appearance of the gel from the outside. PureGEL™ technology is internal and sits below the heel. You can’t see it, but you can feel it.

Another significant advancement on the Cumulus from last year’s model is that ASICS committed to making more sustainable running shoes. More than 75 percent of the upper material is from recycled content. The sock liner is also made with a new, more sustainable dying process that uses roughly 33 percent less water and reduces carbon emissions by about 45 percent.

The shoe’s durability also contributes to a superior lifespan, meaning fewer shoes head to landfills because they stay on their feet longer. ASICS Gel-Cumulus 25 is a running shoe you can feel good about wearing.

How Does the Gel Cumulus 25 Fit?

Our reviewers continuously commented on the ideal fit of the Gel-Cumulus 25. The newly designed, more sustainable upper is snug, yet breathable enough to prevent hotspots, even during summer long-distance runs.

The heel collar has a luxurious feel that cradles the heel without irritating it. The consensus was that the upper is plush yet stretchy, and the new pull tab on the heel makes slipping in and out a breeze. Our reviewers with wide feet felt the Cumulus 25 was as comfortable as did those with lower volume, narrower feet.

Finding a running shoe that fits just right is essential to achieving your fitness and running goals. At Marathon Sports, we’re dedicated to helping you find the best fit.

Stop by one of our brick-and-mortar stores to take part in our Right Fit™ process. We’ll assess your pronation, gait, foot shape, health goals, fitness, and more to help determine if the Gel-Cumulus 25 is the right fit for you. If not, we’ll help you find an alternative that better suits your running style and preferences.

A Fresh New Look

Our reviewers liked the new look of the ASICS Gel-Cumulus 25 so much that it needs its own section. They felt the visible GEL™ technology in the heel of the Cumulus 24 was outdated and reminded them of running shoes from the early 2000s.

The Cumulus 25 offers the improved comfort of PureGEL™ technology without the old-school appearance. The higher midsole is visible without appearing bulky, and the upper is more balanced.

The shoe is more streamlined and sleek, especially in the white/white and black/gunmetal colorways. It’s also available in various brighter colorways for those who want superior visibility on the road or simply a touch more character. Whichever colorway you choose, you’ll feel confident wearing the Cumulus 25 long after your workout and wherever the day takes you.

Pros and Cons

Our team welcomed the improvements ASICS made to previous versions of the Gel Cumulus. Although, they understand that this won’t be the running shoe for everyone. We have outlined the shoe’s pros and cons to help you decide if the Cumulus 25 is the best running shoe for you.

Pros

  • Improved cushioning with PureGEL™ and FF BLAST™ PLUS technologies
  • Superior sustainability in terms of production and materials
  • Discreet gel for a more attractive appearance
  • Lightweight construction
  • Comfortable straight out of the box
  • Cushioned enough for long runs, yet excellent for all running workouts
  • Ideal for neutral pronation and under pronation

Cons

  • Not ideal for runners who overpronate
  • Not made for speedwork (but plenty lightweight)
  • May not offer enough cushioning for runners who prefer maximum cushion

Who Should Wear the Gel Cumulus 25?

The ASICS Gel-Cumulus 25 is for runners with neutral or under pronation. It is not an ideal running shoe for those who overpronate.

Neutral runners tend to have average-sized arches and push off with even distribution among the toes and forefoot. The foot strikes the ground with the outside of the heel and rolls slightly inward. Neutral pronation absorbs shock and is the most balanced pronation. It is also the least likely to cause injury.

Underpronators generally have high arches and push off with more pressure on their smaller toes. The outside of the heel strikes the ground at a greater angle than with neutral pronation. Underpronators experience shock absorption through the lower leg and are more susceptible to ankle strain, plantar fasciitis, and shin splints.

The ASICS Gel-Cumulus 25 offers a great fit for neutral pronation and under pronation. The shoe’s innovative materials provide cushioning for energetic take-offs and shock absorption on landings.

Our team recommends the Cumulus 25 for distance running and everyday training. They see it as an ideal alternative for runners who find the Nimbus 25 too soft or too heavy.

Shop the Asics Gel Cumulus 25 at Marathon Sports

The verdict is in, and our Marathon Sports experts think the Gel-Cumulus 25 will be a favorite among runners seeking a well-balanced running shoe in 2023. It’s lighter and more sustainable, cushioned, and comfortable than all previous versions.

We found the Gel-Cumulus 25 an excellent shoe for everyday training, whether in the gym, on the track, or on the road. Extreme long-distance runners may prefer the Nimbus 25 for its extra cushioning, but those who like a lighter, well-balanced shoe will likely find the Cumulus 25 more suitable.

The new ASICS Gel-Cumulus 25 is now available at Marathon Sports online and in stores. Stop in to learn more about our Right Fit™ or log online to shop the new Cumulus and other top running shoes today.
