    The Asics [Gel] Cumulus 20 is definitely the best Cumulus we've tried so far. I wasn't really a fan of the 17, 18, or 19, but these are solid. Not my favorite shoe, but it's a respectable shoe.

  • 95 / 100 by Road Runner Sports • Matt • Level 3 expert

    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.

  • 92 / 100 by Road Trail Run • Sam Winebaum • Level 5 expert

    As a runner who prefers stable, comfortably yet firmly cushioned and also responsive daily trainers, the Cumulus 20 is my kind of shoe. This is one fine modern design decently lively, stable, and flexible daily trainer which puts ASICS back in the hunt.

  • 90 / 100 by Running Shoes Guru • Frank May • Level 4 expert

    I really liked the changes Asics made from the Cumulus 19s to make these Cumulus 20 shoes, and felt that Asics is true to their word when they claim this shoe is comfortable for all levels of runners while including premium technology with nice styling.

  • 90 / 100 by Phidippides • Brennan • Level 2 expert

    While slightly firmer than the GEL-Cumulus 19, the GEL-Cumulus 20 still maintains the traditional standard-weight neutral feel that runners have come to expect in a Cumulus. It’s less flexible than some of its competitors, but the new FlyteFoam midsole gives it a little more responsive feel than the 19.

  • 84 / 100 by RationallyRunning • RationallyRunning • Level 2 expert

    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.

  • 95 / 100 by Road Runner Sports • Serena • Level 1 expert

    ...lots of good traction underfoot; really, really durable shoe, and just an amazing update.

  • 90 / 100 by The Wired Runner • Ben Drew • Level 1 expert

    If you’re looking for an ultra-supportive shoe that won’t weigh you down, this is a good option.

  • 90 / 100 by DirtyOldSneakers • Eric Rayvid • Level 1 expert

    Overall, nice shoe, comfortable, it gives you a nice return on all the energy you're putting into the ground.

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.

Outsole

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.

Midsole

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.

Upper

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.
