Asics Cumulus 21 Shoe Review
Asics Cumulus 21 Shoe Review
Asics has been around the running world for years. The Asics Cumulus, the Asics Nimbus, and the Asics Kayano are all over 20 models old. A few years ago, Asics changed factories and their shoe quality went down. The shoes were narrow and tight and many people went wider and even a full size larger. Shoe size is just shoe size but when you order the same shoe year after year and suddenly you’re a size bigger, it doesn’t do the brand any favors.
My point with that is from about 2015-2019, Asics was not great. In late 2019, they came out with the Asics Nimbus 22 and it was the first shoe in years I was impressed with from Asics.
Asics does win the award of most consistent with their technology. The same Asics Gel from the 1990s is the same Asics gel now.
Now that we have that long introduction about Asics let’s get to the Asics Cumulus 21, also known as the Asics Gel Cumulus 21. Although there is no non-Asics Gel Cumulus 21 and there is no shoe called the “Asics Gel.”
The Gel Cumulus 21 is a lighter, less cushioned version of the Asics Nimbus 22.
Asics Cumulus 21 Quick Facts:
Weight: 9.9 ounces
Heel to Toe Drop: 10 mm
Asics Cumulus 21 Fit:
The fit of the Asics Cumulus 21 is what so many people are curious about! Now, the Asics Cumulus 21 uses a dual-layer mesh. The toe box is wider and the Asics Cumulus 21 fits more true to size than it has in years.
First, Asics Cumulus 21 now uses a dual-layer mesh. While more durable, the engineered jacquard mesh upper doesn’t breathe as well as I hoped.
One thing I wish Asics would remove (from all of their shoes) is the heavy Asics logo. It takes up a lot of space and just seems like unnecessary weight. Many brands have already gone towards screen printing their logos on shoes, so Asics should go that route too. Although the Asics logo doesn’t hinder anything with the fit of the Asics Cumulus 21, it just adds unnecessary weight.
I do appreciate is the higher heel collar in all Asics shoe. The higher internal heel counter and holds the foot in position. My foot feels secure when running in the Asics Cumulus 21.
In running shoes, I typically wear between a 10-11 wide and I find the Asics Cumulus 11 wide to be the best fit. For a while, I couldn’t comfortably fit into the Asics Cumulus, but I can once again.
Asics Cumulus 21 Ride:
Asics, in general, is one of the heavier brands out there. That’s because Asics uses gel in (most) of their shoes and gel is a heavier substance. While the Asics Cumulus 21 is one of their lighter offerings, it’s still heavier compared to the Saucony Ride, Brooks Ghost, or Hoka Clifton. The Cumulus 21 is no different. The following is some of the features for the midsole and outsole of the Cumulus 21.
The staple in most Asics shoes is the silicone-based gel, which absorbs shock. Gel is no better than other cushioning systems, but there is more cushion in the heel. The rear and forefoot gel technology is designed for shock absorption with a Flytefoam, low-density foam, in the midsole.
The midsole is made up of both Flytefoam and Flytefoam propel midsole technology. What is Flytefoam? It’s softer, low-density foams that provide bounciness and responsiveness. Asics introduced Flytefoam into many of their staples shoes to reduce weight but also provide a more responsive ride. With the mixture of foams, I’ve found the Asics Cumulus 21 to provide responsiveness no matter the type of run.
Finally, like many shoes, the Asics Cumulus 21 uses “AHAR,” also known as ASICS High Abrasion Rubber. The rubber makes it great on rainy, wet, or icy days. If it’s icy or snowy, I’m more likely to grab the Asics Cumulus 21.
The Flytefoam Propel Technology, together with the rearfoot and forefoot gel technology, makes the Asics Cumulus 21 the softest and most responsive ride in a long time.
I’ve run a few different types of runs in the Asics Cumulus 21 and I find the best use is as a daily trainer or a shoe I’m standing around or at the gym in. I prefer the durable gel for long days at work or to reduce shock on easy runs. Lately, I’ve used the Asics Gel Cumulus 21 a lot for warmups and cooldowns for workouts and races.
Asics Cumulus 21 Conclusion:
The updated Asics Cumulus 21 is better than it has been in years. It’s exciting to see Asics getting back in the game. The Asics Cumulus 21 fits more comfortably and is a great trainer for someone looking for an everyday shoe for easy runs. It’s one of my favorite shoes to stand around, go to the gym, or even work in (yes, a running shoe that I use a lot for nonrunning). If you’ve run in the Asics Cumulus before, the major changes are the upper and a better fit than previous versions.
