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.
