    Asics Gel Cumulus 20 (Women): Impressively Awesome Neutral Shoe

    The version, and it continues to impress me.

    It features several updates to enhance breathability, cushioning and overall performance. The updates include the following:



    • The upper is different from the old Gel Cumulus 19 uses a new jacquard mesh material for breathable coverage. It has enough perforations to allow air to pass through efficiently, keeping the foot well-ventilated throughout the run. It also offers glove-like fit for comfort.
    • The FlyteFoam Propel technology is also placed in the midsole. It offers runners a comfortable, responsive underfoot cushioning. It is lightweight and durable for long-lasting performance.
    • The outsole has a new tread pattern for enhanced traction, and the Guidance Trusstic System has been removed for a smoother transition.

    Technologies and design




    • Jacquard mesh – This material offers a breathable coverage and customized fit. It is durable, lightweight and comes in a seamless upper design.
    • Personal Heel Fit – For a more personalized fit, the shoe has two-layer memory foam in the heel collar.
    • Discrete Eyelets – The eyelets were designed to reduce tension when the shoelaces are tightened. The independent holes enhance the overall fit and comfort of the shoe.
    • Reflective details – Reflective details on the heel area offer added visibility during low-light condition.




    • FlyteFoam – A notable midsole technology, which offers lightweight and durable cushioning throughout the run. The midsole foam delivers a responsive and springy ride.
    • Flytefoam Propel – Another layer of midsole cushioning which offers added responsiveness and underfoot comfort.
    • Impact Guidance System (I.G.S) Technology – It aims to deliver adaptive and dynamic stability. It aids the foot for a more balanced, smoother heel-to-toe transition.
    • Gel cushioning – Offers better shock absorption for enhanced running performance. It is specifically placed in the forefoot and rearfoot for better a smoother transition.




    • Asics High Abrasion Rubber (AHAR) – A durable rubber material that gives protection to high-wear areas. It gives added traction without affecting responsiveness and flexibility.
    • DuraSponge Rubber – A blown rubber compound placed in the forefoot which gives added flexibility and cushioning.

    Performance of the Asics Gel Cumulus 20

    The performance of the Asics Gel Cumulus 20 on the road is truly impressive. I have been an Asics fan for a few years, and this neutral running shoe did not disappoint. I like the lightweight construction as well as the responsive cushioning. It feels so light and fast on my feet.

    I always admire the FlyteFoam midsole and Gel cushioning. These materials made my running experience more responsive and well-protected. The shoe is strikingly responsive and flexible.

    The outer sole of the shoe is very durable as well, thanks to the AHAR and DuraSponge rubber. They provide reliable traction on the road. The grooves in the outsole also offer added flexibility, making every stride even more satisfying.

    Overall, I am truly happy with this road running shoe.

    Fit and durability

    Just like my other Asics running shoes, the Cumulus 20 is true to size. I love the roomy toe-box. It gives my toes more freedom to move freely. The forefoot is not tight as well. I am a medium-footer runner, and the shoe fits like a glove on my fit.



    I had one issue though. At first, the heel area felt too tight; maybe because of the memory foam added in the heel collar. It was a small issue, and it did not stop me from wearing this shoe.

    Thankfully, after wearing the shoe more than ten times, the tight heel fit started to loosen, and now, it fits perfectly – no heel pressure, no discomfort.

    Comfort and breathability

    The shoe is breathable and comfortable enough for long-distance runs and long-hour wear. I love the seamless design and the jacquard mesh upper that wraps my foot like a glove.

    The mesh is stretchable, and it notably conforms to the shape of my foot. Also, the cushioning offers comfortable underfoot protection without affecting ground contact.

    • Responsive and flexible

    Asics Gel Cumulus 20 (Men’s): Premium Technology, Redefined Design

    The Gel Cumulus model has been the favorite of many for 20 years now. It is one of the Asics well-received road running shoes, and it continues to wow several Asics fans.

    Now on its 20th iteration, the shoe features an updated design and premium technologies for better performance. Aside from its impressive ride quality, the shoe also has a good-looking design, making it suitable for casual days.


    The design of the Asics Gel Cumulus 20

    version of the Gel Cumulus offers a redefined design to enhance the running experience of every runner further. It aims to provide a comfortable, smooth, flexible, and responsive performance on the road.

    The major update of this model can be seen in its midsole. Asics uses its new midsole foam – the FlyteFoam Propel. This technology further enhances the performance of the FluidRide and FlyteFoam cushioning. It gives an additional layer of foam for enhanced comfort and responsiveness.



    Designed for long-distance road running and quick-paced training, the men’s version of the Cumulus 20 weighs 285 grams while the women’s version weighs 236 grams. It has a heel drop of 10mm and is available in both medium and wide widths.

    Comfort and breathability

    The upper of the Asics Gel Cumulus 20 is made of a jacquard mesh material which offers maximum breathability and comfort. Strikingly, it keeps my foot cool and dry even after a long run.

    Since it has a seamless design, the upper mesh wraps the foot comfortably while also reducing the possibilities of hot spots and blisters.



    The overall comfort and breathability of the shoe is remarkable. It is comparable to the New Balance Fresh Foam Zante v4 which also employs a jacquard mesh with no-sew design in its upper.

    Performance of the Cumulus 20

    I have read some reviews about the old Asics Gel Cumulus 19. Several users mentioned that the midsole of the 19th version was not responsive as expected. It feels lightweight but not bouncy.

    Thankfully, I did not experience it with the Gel Cumulus 20. The cushioning of the shoe offers a good amount of bounce, and it is very comfortable. I think the improvement in the shoe’s performance is due to the FlyteFoam Propel, a lightweight cushioning that gives added bounce and softer feel.



    When it comes to the overall grip, the outsole offers an impressive level of traction for road running and even in light and even trail surfaces. It is made possible by the AHAR and DuraSponge rubber materials which also deliver added durability and flexibility.


    The Asics Gel Cumulus 20 runs half-a-size small, and they have a very tight fitting. It is not manageable even with thin socks.

    There’s a lot of pressure on the forefoot and heel. The toe box is not roomy at all. To get the right fit, one must pick a larger size. Users should try the shoe first before purchasing a pair.



    The Cumulus 20 is impressively durable – from the upper to the outer sole. Most of my Asics running shoes are durable, and I’m happy that this pair did not disappoint me. I have worn the pair for several miles already, and it still looks like new – no significant wear even after using them on light trails.


    Good points

    • Lightweight
    • Durable
    • Good-looking design
    • Responsive and comfortable cushioning
    • Flexible
    • Good amount of traction on paved surfaces
    • Breathable and comfortable in-shoe feel

    Bad Point

    • Tight fit




    I love the overall design and enhancements made to the Cumulus 20. They look fashionable, and they are responsive and lightweight at the same time.

    The shoe is ideal for long-distance runs and daily training. Though they feel tight, I would still recommend this shoe for runners who are looking for an affordable yet well-performing road shoe.

  • 95 / 100 | Road Runner Sports

    It's been a fan favorite for over [sic] 20 years and there's lots of reasons why, and even more reasons now: It's super responsive, super cushioned, and its lighter weight -- you will love this shoe.

  • 84 / 100 | RationallyRunning

    If you're just looking for a new shoe to try, [this is a] great moderate-cushioned shoe. The only thing is if you're a smaller human being, this may be a little bit too much of a shoe for you.

Updates to Asics Gel Cumulus 20

  • Asics has released the 20th-anniversary version of the Gel Cumulus, and in this iteration, updates are presented through new materials that deliver an equally new fit-and-feel. While the shoe maintains a standard-weight structure and the familiar silhouette of the Gel Cumulus, this edition claims a more robust platform and a softer cushioning compared to previous releases.
  • The upper displays a broader and higher toe box than the one in Gel Cumulus 19. The overall fit aims to be more snug and secure, as the heel cup and the ankle collar are now firmer. While the Gel Cumulus 20 retains the Discrete Eyelet™ in its lacing system, a new structure present is the reflective strip in the heel area.
  • The midsole of the Gel Cumulus 20 has kept most of the technologies of the previous version. The only noticeable changes are the addition of a new cushioning compound and an updated sock liner. Meanwhile, the outsole brings back the DuraSponge® component which was included in the 18th iteration but not in the 19th.

Asics Gel Cumulus 20 size and fit

The Asics Gel Cumulus 20 features standard running shoe length, sizing, and weight. The shoe runs true-to-size, and accommodates wearers of all foot volumes, thanks to the width options of medium and wide for both the men’s and women’s versions.


The Gel Cumulus 20 combines two distinct types of resources for its outsole – the Asics High Abrasion Rubber (AHAR®) and the DuraSponge®. Both materials work together to give the foot full ground contact and a stable ride.

First, the AHAR® compound is found on the shoe’s critical, high-wear areas. With its abrasion-resistant quality, the shoe levels up on durability while maintaining the capacity for traction. It uses the same rubber that forms car tires; thus, runners are sure of its toughness.

Next, the DuraSponge® rubber makes up the rest of the outsole. While it is also resistant to damage, this compound is made of blown rubber, making it a little bit softer than AHAR®. This permits the underfoot a comfortable ride and qualifies a flexible stride.


The most notable update in the Gel Cumulus 20 is the utilization of FlyteFoam® technology in the midsole. This system aims to provide a consistent level of reaction, even for long distances. The Flytefoam® method uses unique organic fibers to form a cushioning that is 55% more lightweight than traditional midsoles. Aside from responsiveness, Flytefoam® also guarantees a flexible and resilient fit all throughout the run. These qualities help in making the Gel Cumulus 20 a durable shoe.

The main midsole component of the shoe is the FluidRide®, which is the combination of Solyte™ and SpEVA™, both cushioning compounds exclusive to the brand. FluidRide® is lightweight yet sturdy, and it helps improve running performance through its shock-absorbing and high-rebound properties.

Like all other Gel shoes, the Gel® cushioning system makes its way into the forefoot and rearfoot areas of this shoe. The Gel® zones act as shock absorbers through the gait cycle. As smooth transitions are achieved, the foot is enabled movement in different planes.

The Gel Cumulus 20 also employs the IGS®, short for the Impact Guidance System. IGS® is the term for the design of the shoe that aims for dynamic and adaptive stability. IGS® uses the Guidance Line® as a tool to help achieve the goal. With Guidance Line®, the center of pressure is adjusted, thus improving balance and gait efficiency.

An OrthoLite® sock liner supplies additional cushioning and underfoot protection. It has an antimicrobial property that promotes a healthy foot environment.


The stretchable Jacquard mesh upper gives the Gel Cumulus 20 a flexible, customized fit. Its elasticity is multidirectional, which brings freedom of movement. The mesh is reinforced in strategic areas to lend the shoe a supportive framework. With seamless construction, the shoe has fewer chances of causing skin irritation.

A Discrete Eyelet™ feature is present in the lacing system of the shoe. These are independent holes that target a custom-fit and enhanced comfort, as they reduce the tension that is caused by tightened shoelaces going through a single eyelet.

The upper also possesses a reflective strip in the heel area to allow prominence in low-light conditions.
