89 / 100 based on 6 expert reviews

  • 93 / 100 | Runner's World | Level 5 expert

    At just $120, the Cumulus remains a bargain-priced, high-mileage shoe.

  • 83 / 100 | Solereview | Level 5 expert

    It’s got a sorted, well cushioned ride which behaves better than the Nimbus. The upper fit and feel doesn’t have much to complain about, but the material package is far from impressive.

  • 92 / 100 | Running Shoes Guru | | Level 4 expert

    The Cumulus returns with a version that is not only lighter, but has a few improvements that have enhanced the shoes already well cushioned and smooth ride. A great neutral shoe for the high mileage runner.

  • 93 / 100 | The Running Shoe Review | | Level 3 expert

    The shoe offers stability where you need it, and comfort in any position.

  • 86 / 100 | VBM Best Reviews | | Level 2 expert

    Whether you are on a treadmill or on a road or in a jungle, you can comfortably wear this shoe without getting tired or fatigued quickly. 

  • 82 / 100 | Active Gear Review | | Level 1 expert

    Even though it’s a slightly heavier stability shoe, I was able to test its versatility on a wide range of sufaces and in extreme conditions.

  • A fluid ride is part of what the Asics Gel Cumulus 16 is capable of providing. The materials and components that are at work here are all of high quality and they ensure the optimum comfort of the runner. Structure-wise, this shoe is reliable. It wraps around the foot in a snug manner, but it doesn’t make it feel too tight. The underfoot platform is soft and responsive. Even the outsole is crafted to act like a shield against abrasion and wear.
  • The upper unit of this Asics shoe makes use of a mesh material that employs an open construction. It allows air to easily enter the foot-chamber, circulating within it and keeping the foot cool. The design is appealing because it utilizes modern-day color schemes and designs. It is sure to capture attention through its use of bright hues and unique color spectrums. Reflective materials are added to the overlay system, making it visible under low-light conditions.
  • The mid-sole unit uses the FluidRide™ technology, a foam unit that features enhanced cushioning, durability and bounce-back mechanics. Runners are going to be able to spring back up easily and with energy because of this unit. Shock absorption is also provided via gel-like add-ons in the front and back of the platform. The mid-foot is also provided with support, so those with problems with foot pronation are going to get the support they need when running.
  • Durable rubber is placed to protect the sole unit from any abrasion or wear that might affect its efficacy or functionality. Liberally used as the external sole unit, it surely shields the shoe from surface friction and other unsavory effects of continued use. Traction is also provided, thus making it easier for runners to traverse the asphalt.

The 16th version of the Asics Cumulus runs a bit small. It is recommended for runners to purchase ½ size in order to get a more relaxed fit. The width of this shoe is medium, so it accommodates those with medium-sized feet. It is worth noting that the toe box is slightly wider to allow natural splaying of the toes. This shoe’s semi-curved shape follows the natural curvature of the human foot.


The outsole unit of the Asics Gel Cumulus 16 utilizes the AHAR or the Asics High Abrasion Resistant Rubber. It is the same material as the outsole of the Cumulus 20 and it is one of the most robust rubber technologies on the market. It is able to protect the rest of the sole unit from wear and tear. As a reliable road shoe, it provides reliable traction on a variety of paved surfaces.


The mid-sole unit has the FluidRide™, which is a technology that combines bounce-back mechanics with responsive cushioning, essentially making the platform as comfortable and as tuned to the performance needs of the wearer. It doesn’t have a heavy weight, but it is durable at the same time.

The Gel® Cushioning System is a silicon-based unit that’s placed in the forefoot and rear areas of the Asics Gel Cumulus 16. It is able to attenuate shock while also adding more cushioning to the platform. This cushioning is also used in the notable Kayano 25 running shoe

Midfoot structural integrity is maintained by the Guidance Trusstic System. Combined with the Guidance Line, the gait becomes more efficient and more balanced.

The ComforDry Sock Liner adds a bit more cushioning as it’s the unit on which the foot is going to stand. It has anti-microbial and anti-moisture properties, thus allowing it to maintain a clean and a healthy interior environment.


The upper unit features a breathable mesh material that has an open construction. This lightweight fabric wraps around the foot securely, but it doesn’t make it feel restricted. It’s soft and smooth.

Synthetic overlays are stitched onto the upper fabric. They provide structural integrity to the upper, and their glossy parts make the shoe more visible. But they help in hugging the foot by working with the shoelaces as they are being adjusted.
