69 / 100 based on 3 expert reviews

  • 71 / 100 | Solereview | Level 5 expert

    Asics’s mid-priced neutral trainer is adequately cushioned for the long and easy runs, featuring the same sole unit as the 18. The upper toe-box still fits shallow.

  • 60 / 100 | Running Shoes Guru | | Level 3 expert

    The Asics Cumulus 19 is an ever-reliable daily trainer and long-run shoe that will last mile after mile. However, the shoe’s weight and stiffness are not ideal for faster workouts such as intervals or quick tempo runs.

    All and all this is a great update and I have weartested a pair for the last 2 months and must say the fit improved from the 18 and ride underneath the foot is great!

  • The Asics Gel Cumulus 19 is a road running shoe that’s created for people who have neutral foot pronation. Not much has changed when compared to the previous iteration, but this one has a more stylish design to appeal to the evolving preferences of consumers.
  • A mix of stitched and printed overlays graces the upper unit of the Cumulus 19. They don’t encompass the main mesh material as much as the 18th version, therefore allowing more air to seamlessly enter the foot-chamber.
  • A robust set of technologies makes up the midsole unit. As a cohesive whole, they essentially aim to keep the foot as comfortable and as secure as possible. Impact protection is also a highlight of the underfoot platform.
  • Durable rubber covers the mid-sole foam and protects it from the potentially abrasive nature of the asphalt. Wear and tear threaten efficacy and longevity, so it’s this layer’s job to shield the shoe from such consequences. Flex grooves are also present and they allow the foot to move more naturally through the gait cycle.

The Asics Gel Cumulus 19 fits small, so it is advised to get ½ size larger than the regular preference to accommodate a more relaxed fit. The widths for the men’s version are D – Medium, 2E – Wide and 4E – Extra Wide. For the women’s version, it’s 2A – Narrow, B – Medium and D – Wide. Its semi-curved shape follows the natural curve of the human foot.

The outsole unit of the Asics Gel Cumulus 19 makes use of the AHAR® or the Asics High Abrasion Rubber, which is a durable material that’s meant to protect the mid-sole from the abrasive nature of the roads. This is also the outsole material of the Cumulus 20 and this material aims to give added traction.

In the forefoot section is DuraSponge. Made from blown rubber, it delivers additional springy cushioning on top of its protective purpose.

Flex grooves are also added into the outsole. They essentially accommodate the natural motion and flexibility of the wearer’s foot as it goes through the process of stepping onto the ground and lifting off of it.

The FluidRide is a full-length foam unit that aims to deliver a responsive ride in a durable and lightweight unit. It carries the foot well and keeps it cushioned throughout the running session.

The Gel® Cushioning System is a silicon-based material that’s placed separately in the heel and forefoot sections of the platform. Shock absorption and additional cushioning is the name of the game for this material.

The Guidance Line is a vertical flex groove that enables the foot to move more naturally and efficiently through the gait cycle.

The Guidance Trusstic System is a support system in the mid-foot section that prevents underfoot bucking and breakdown during the run. It essentially acts as a foundation that steadies the structure and form of both the foot and the mid-sole unit.

The IGS or Impact Guidance System is a design that allows the runner to land efficiently on the ground and transition towards the toe-off more effortlessly.

Additional underfoot cushioning is provided by the ComforDry Sockliner. It also offers anti-microbial protection and a moisture-wicking capacity.

The upper of this Asics running shoe uses an open mesh, which is a breathable fabric. It accommodates environmental air into the foot-chamber, thus giving a cool and dry interior for the wearer.

The Seamless Construction of the upper gives the runner the option to use the shoe without wearing socks first. The soft interior construction prevents the influx of skin irritation.

The Personal Heel Fit or PHF makes use of memory foam to fill the collar of the Asics Gel Cumulus 19. The foam adapts to the upper portion of the foot, giving it enough cushioning and security while also preventing the feeling of tightness.

A mix of stitched and printed overlays graces the main fabrics. While providing structure to the upper, they also help in changing the fit to accommodate the preferences of the wearer. They are connected directly to the traditional lacing system, so they tighten or loosen in accordance with the adjustments made to the shoelaces.
