Asics Gel Cumulus 20 Review Facts
Watch Video Review

Asics has been manufacturing the Gel Cumulus model for many years now. It is one of the most popular options that the brand has on the market today. This newest version – the Asics Gel Cumulus 20 – just dropped in July of 2018 and already has a huge following online. The company completely overhauled this version, rebuilding it from the ground up. Instead of EVA-foam in the midsole, there are two different layers of FlyteFoam. The outsole is completely redone, as we said ‘goodbye’ to the plastic trussic shank midfoot and ‘hello’ to two different types of rubber compounds. Reviews for this version are mostly positive and we’ve almost been convinced to buy a pair for ourselves. Let’s take a deeper dive into what makes the Gel Cumulus 20 so great and see if these kicks really stand up to what consumers can throw at them.

Positive
  • These were a dream right out of the box. They look great and are super stable. They helped me improve my stride and run time.
  • I collect sneakers and these are top 5 most comfortable I own. They have some really nicely designed heel support. Fit and feel great.
  • I have had them for a couple months now and they still look great with daily use. They are comfortable and versatile from casual to gym. They have tons of support and are a great shoe.
  • These have the Gel in there and it has relieved all my heel pain from surgery. They have also really helped with my underpronation.
  • They look good, they feel good. I love Asics and these have stood up to the rest. They are about as near perfect to a shoe as you can get and the heels are a dream. They are also really light!
  • This is hands down the best Cumulus ever made. I mean, I have had them all and the last pair I had for 3 years. These are so cushioned and supportive. They upgraded every aspect of an already amazing shoe.
  • As a podiatrist, we always recommend Asics. These specifically are some of the best supportive shoes they have ever made They are the kind of shoe you can wear all day.
  • These only lasted for about 5 months. But, They were the best Asics I have ever worn. They do not pinch me in the mid section and are great for my forefoot strike pattern. They gave me a better run time. They have lots of toe room too and really support the whole foot on impact.
  • I have had surgery on my feet and sometimes I have a hard time finding a shoe. This one is a dream come true. They’re so comfortable and I am able to walk without pain. I really love these shoes.
  • I have bursitis and really high arches. THese shoes accomodate all of this without discomfort. I am able to run and walk throughout the day without any frustration. Very impressed with this being my first Asics experience.
  • I use these as my daily runners and I am so happy with them. They are so supportive and comfortable. A real dream shoe. I have had them a couple months and they seem to be holding up great! Great arch support too.
  • Have wide steep arches. I had the 15 forever! I finally had to give in and get another pair and these are so good, maybe even better. I would have to say the best shoes on the market.
  • Super light , supportive and cushy shoe. They offer a really nice support for my achilles.
  • I skipped the 19 because the toe box was smaller. They definitely widened it on these and the shoe is so perfect; I am over the moon. I bought them a half size larger but they are very comfortable and such a nice and refreshing upgrade, they never give me any pain.
  • I would compare these to running on pillows. They absorb every impact with that of grade a mattress. They fit perfect to size and have such a nice look to them. I would recommend these shoes for sure.
  • I switched over to these from Brooks. They have so much support and the comfort is perfect. They are cushioned and they were sized like a normal shoe.
  • These worked magic once I got them broken in. They were snug and a bit stiff at first. They have some great support and cushion while still being super light. They have a nice thick sole, which I found dreamy.
  • They really snug your feet without being overly cramped and aggressive. They have super comfort in the heels and the gel really molds to your foot. I am a heel striker, so this is special. They are super light and do not cause fatigue.
  • I am going to use these for my summer shoes. They breathe really well and have tons of cushioning and stability for longer runs. They were a half size too small.
  • The heel is narrow and the toes are roomy. They have a nie flexibility to the mid and toe section as well.The mesh breathes like an air conditioner for your toes. The colors are really nice and low key too.
  • These ran a bit more narrow than am used to for Asics. They did need a bit of breaking in.I am happy the toe box wasn’t more narrow though so they hug just right and leave space to wiggle. I am able to we are these shoes for longer periods of time without any problems.
  • Plenty of toe room and they don’t make my feet seat, YAY! The gel design forms to my foot every time I step in it without losing any integrity within the shoe. They have nice colors and designs as well. Super low key, comfortable shoe.
Negative
  • I am a huge Asics fan but these really fell short in my opinion. These ran so much smaller, an issue I have never had with Asics. My large toe was screaming to get out. CONSISTENCY PEOPLE!
  • This shoe was lacking so much cushion comparably. They are stiff and flatten out way too quick. They are also really slippery inside the shoe. Just such a disappointment compared to the older models of the Cumulus.
  • These have changed so much. They are so freaking narrow it isn’t even the same type of shoe. They gave me tons of blisters. I hated them.
  • I feel like they keep getting smaller and smaller. The shoe itself didn’t bend with my feet and the break in time never came. I was shocked that the toes were so cramped as well. Asics is going to the crapper with every new model. I am so disappointed.
  • These had tons of hot spots due to how stiff they were. I had blisters in all sorts of awkward spots.Too rigid and uncomfortable, I returned them.
  • These had no sole support and they seemed like planks of wood. They were lacking flexibility and cushion. They also seem to be more narrow than any other Asics I have tried.
  • These lacked the arch support I am used to with the Culumus. They had a narrow than average toe box. They were so uncomfortable and lacked tons of cushioning the others offered. Why would you downgrade your shoes ASICS?
  • These rubbed my ankles raw. THey were so stiff and rigid and really uncomfortable. I am not sure why they changed them but no go!

Outsole
Outsole

Outsole

The outsole of the Gel Cumulus 20 features two different types of materials - Asics High Abrasion Rubber (AHAR) in the heel portion of the shoe and DuraSponge material, making up the rest of the outsole. The AHAR compound is found in high-wear areas and is present to help not only the durability of the shoe but the traction it provides as well. It is abrasion-resistant and runners will find that it can really take a beating. The DuraSponge material is made of blown rubber and is present to provide a comfortable underfoot ride as well as flexibility. By removing the stiff trussic plastic that was present in the 19, this newer iteration seems to provide a smoother ride. There are a ton of flex grooves with a segmented crash pad in the heel. Similar to its predecessor, the 20 has a single rubber lug over the midsole that runners will find takes the brunt of rearfoot landings.
Midsole
Midsole

Midsole

Instead of using a plastic support truss in the midsole area as previous iterations of the Gel Cumulus have been known for, the 20 features a softer and more bouncy FlyteFoam Propel layer. This is one of Asics newer technologies that utilizes a lightweight foam to help decrease drag during runs. The Propel provides runners with a high-energy return and an unrivaled toe-off which should ultimately help to maximize performance. This shoe also features Asics traditional FlyteFoam material for resiliency. This technology uses organic fibers to provide a cushioning in the shoe that is 55% more lightweight than other midsoles available on the market. The main component of the midsole is Asics FluidRide tech. This helps to give runners a responsive ride that is well-cushioned as well as a lower shoe weight and added durability - a home run for running shoe enthusiasts to be sure. Both the heel and forefoot of the 20 features gel inserts to help absorb shock and to aid with smoother transitions. An OrthoLight sock liner is present in the Cumulus 20 which helps to provide even further cushioning as well as help to protect the underfoot. The antimicrobial properties found in the sock liner ensure that the environment inside of the shoe will remain healthy and free from bacteria.
Upper
Upper

Upper

Asics really upped their game with the 20th iteration of the Gel Cumulus by totally overhauling the upper. This new version features a stretchy jacquard mesh material that not only breathes better than older versions of the shoe, but it helps to provide a lighter feel as well. Gone are the heavy plastic overlays that we saw in the Cumulus 19. This new mesh material features multidirectional elasticity that provides a flexible and customized feeling fit. It’s reinforced in certain zones on the upper to help give a more supportive framework for your foot. The lacing system features Asics Discrete Eyelet system that has independent holes to help provide an even more custom fit as well as up the level of comfort.
Weight
Weight

Weight

The men’s version weighs in at 10 ounces, while the women’s comes in at 8.3 ounces. In the predecessor, the shoes weighed a full ounce more in the men’s version and about half an ounce more for the women’s. A lot of reviewers found that this shedding of weight really made a difference during their runs. This lower weight is due in part to Asics using their Flytefoam material in the midsole, which is known to be 55% lighter than traditional midsoles.
Breathability
Breathability

Breathability

The upgraded upper in the Gel Cumulus 20 provides a new jacquard mesh material that helps to provide breathability for the wearer. It features a number of perforations in the material to allow for airflow to occur. This material will definitely keep your feet well-ventilated throughout any distance run.
Comfort
Comfort

Comfort

The Gel Cumulus 20 is a comfortable shoe. The upper features mesh that is both stretchy and conforming to the shape of each individual foot for a customized feeling fit. It features a soft heel padding as well as a roomy forefoot and toe box region, which would definitely appeal to runners who have issues finding shoes that have enough space in that section for their feet. Nearly all of the reviews that we perused praised how comfortable these shoes were to run, walk and live in. That said, however, one reviewer mentioned that while the shoe was comfortable enough, it didn’t have the entirely plush and cloud-like feeling that one would come to expect from a shoe with a cloud type in its title. Other negative comments regarding the comfort level of the Cumulus 20 were that it was an entirely different feeling than its predecessor. Some reviewers commented that the ride was firmer in this version, though that isn’t necessarily a bad thing.
Style
Style

Style

The Gel Cumulus 20 doesn’t stand out much, in terms of style. It is a typical running shoe, perhaps a little bland if anything. The men’s version is available in eight different color combinations from neutral colors like white, grey and black to brighter options like red and blue. The women’s version is also available in eight different options, though a little brighter and livelier choices are available here. Colorways range from black/coral to orange/fuschia and blue/pink.
Durability
Durability

Durability

It seems as if the Gel Cumulus 20 is more durable than its most recent predecessor. The structural integrity of the updated upper is stronger and more resilient than in the 19. The introduction of the FlyteFoam midsole in this 20th iteration really gives the shoe a longer lifespan than what was found in the Cumulus 19. The Asics High Abrasion Rubber found on the outsole of the shoe really helps the 20 level up in terms of durability as well.
Protection
Protection

Protection

As previously mentioned in our review, the Gel Cumulus 20’s outsole features Asics High Abrasion Rubber. This material will provide protection to the high-wear areas of the shoe as well as help to provide traction as well. The FlyteFoam and gel cushioning found in the midsole of the shoe not only give the runner a more responsive ride but these technologies help to keep the runner protected, too. When your shoe fits right, is breathable, and adequately comfortable, runners will be less likely to develop painful blisters and sores that can be caused by too much moisture being present in the shoe for extended periods of time. The new jacquard mesh is seamless as well, which is less likely to cause skin irritation on sensitive areas of the feet. Speaking of healthy feet, the OrthoLite sock liner not only provides additional cushioning for the runner but also boasts antimicrobial properties that ensure a healthy environment inside of the shoe. Also found on the upper is a reflective strip so that runners will be seen better in low-light conditions.
Responsiveness
Responsiveness

Responsiveness

Thanks to Asics FlyteFoam tech found in the midsole of the Gel Cumulus 20, these shoes give runners a consistent level of reaction, no matter the distance. The heel ride is particularly responsive as well, without feeling like you’re strapped into a set of bricks. In the 20th iteration of the Cumulus shoe, there is an introduction of a new layer of foam – FlyteFoam Propel - that helps to give the runner a feeling of a soft and bouncy ride. The Propel foam works alongside the regular FlyteFoam technology to provide the wearer with stability and cushioning as well as an all-around responsive ride. Also found in these shoes is Asics’ FluidRide technology in the midsole. This feature helps to provide runners with a bounce back and exceptional cushioning without adding to the weight or taking away from the durability of the product.
Support
Support

Support

One reviewer mentioned that it felt that the guidance system found in the Gel Cumulus 20 tries to control the landing mechanics of their gait. They felt these shoes would work well for folks who under pronate as they typically need a little extra support there.
Terrain
Terrain

Terrain

Though these shoes are far from a typical trail running shoe, the outsole actually provides an impressive amount of traction. Considering that the Gel Cumulus 20 is marketed as a road running shoe, most reviewers were impressed with how well the shoe stood up on trail surfaces. This is because the AHAR and DuraSponge materials that make up the outsole really provide a durable shoe that can take a beating. Though we wouldn’t necessarily suggest you wear these for all of your trail runs, especially long distance ones, you can rest assured knowing that they can stand up against some of the terrain Mother Nature throws your way on the trails.
Price
Price

Price

The MSRP of the Gel Cumulus 20 is $120. Consumers should be able to find some color and size options available on Amazon for less than the MSRP, though we noticed some of the size/color combinations skyrocketed to nearly twice the price.
Traction
Traction

Traction

The traction in the Cumulus 20 has been greatly improved over the previous version of the shoe. The Guided Trusstic System we saw in the 19th iteration has been taken out and replaced with an entirely new tread pattern to help increase the traction capacity of the shoe. The AHAR material on the outsole is abrasion-resistant which not only helps up the level of durability in the shoe, but it increases the traction it can provide a runner as well. Reviewers mentioned that they wore these shoes in dry and slightly wet conditions and that the 20 held up just fine.
Flexibility
Flexibility

Flexibility

The outsole of the Cumulus 20 features a number of flex grooves for added flexibility. The forefoot offers some flexibility while the outsole’s AHAR and DuraSponge rubber materials delivered some degree as well. Many reviewers commented that the 20 felt less flexible than some of its predecessors, but that didn’t seem to deter them too much from purchasing the shoe anyway.
Stability
Stability

Stability

The Gel Cumulus 20 uses Asics Impact Guidance System (IGS). The goal of this technology is to provide dynamic and adaptive stability for every runner that encourages the foot to move in a natural way. The shoe achieves this by working with each runner’s foot, rather than trying to overtake it. The heel of this shoe is cushioned and shock-free. This is definitely a great running shoe option for folks who prefer something that gives them a little more stability.
Drop
Drop

Drop

The Gel Cumulus 20 shares the same heel-to-toe drop as its predecessor – a standard 10mm. The heel height for the men’s version is 23mm while the women’s comes in at 22mm. The forefoot height for the men’s shoe is 13mm and the women’s is 12mm.

Key Features

-Asics Rear Foot & Forefoot Gel technology to help absorb some shock during impact and toe off phases of your stride
-Jacquard mesh upper comprised of multi-directional stretchy mesh material for a close fit
-Flytefoam Propel tech in the midsole for added responsiveness and cushioning
-Flytfoam Lyte tech in the midsole, made of fibers that are 55% lighter than industries standards
Bottom Line
Bottom Line

Bottom Line

The general consensus is that Asics really upped the bar with the Gel Cumulus 20. It seems to be better than its predecessor in nearly every way. The shoe is lighter, the upper fits better, and the outsole is more durable than ever. One of the negative comments we kept seeing during our research was the 20 felt to be a bit firmer of a ride than the previous iteration. This isn’t necessarily a bad thing, however. It depends entirely on the runner and their preference. A shoe that provides a firm and more supportive ride could be an attractive quality for runners who need that kind of support.
