80 / 100 based on 7 expert reviews

  • 85 / 100 | Sportskeeda | | Level 5 expert

    We see an open mesh and a highly breathable upper. The ventilation of this shoe is supreme.

  • 85 / 100 | Sportskeeda | | Level 5 expert

    The ride is very comfortable and from the stability point of view, the shoe is top-class. 

  • 80 / 100 | Canadian Running Magazine | Level 5 expert

    A solid option for neutral or mild supinators.

    So while it is true that the Cumulus 17 ends up being a softer riding version of the previous version, there are three parts which feel markedly different from the 2014 Cumulus. The first part concerns the forefoot. Since the foam gets softer and the transition groove wider, there’s decreased insulation between the foot and the outsole rubber.

    The ride gets softer at the cost of transition. Forefoot gets narrower, yet the upper is an overall improvement.

    The traction on the unit is superb. While running on different surfaces and under different conditions — including in heavy rain — there was no point in time where the shoe slipped.

  • The most noticeable update of the Asics Gel Cumulus 17 is the cushioning in the rear and forefoot areas. The entire sole is updated by adding the FluidRide system into the Gel system to increase and enhance the cushioning, making this shoe softer for longer rides. The cushioning throughout the sole also provides a soft sensation and a ton of support for the gait.
  • The upper of this neutral running shoe is also improved with seamless construction. There are overlays used for added support and protection. Breathability is also given importance while the space in the toe box area is ample for a free and enjoyable movement.

The 17th version of the Gel Cumulus has a standard running shoe width and length. It delivers a comfortable fit from the heel area to the forefoot. It also has a roomy toe box area with a snug fit feel even for a narrower foot or smaller size foot.

The outsole of the Cumulus 17 has the AHAR or the Asics High Abrasion Rubber. It provides the responsiveness, flexibility, and cushioning while keeping the foot protected from shock and abrasion. This rubber material ensures that the traction is superb for all types of weather and surface, even on wet grounds during heavy rains.

In the outsole is placed the Guidance Line, which is a line-structured for more flexibility, support, and stability.

The midsole of this shoe features an improved construction. The Gel cushioning technology, which is also used in the Gel Cumulus 20, is combined with the FluidRide cushioning system, which is an evolution in the midsole technology. It provides not just the adaptability but also the bounce and the softness while keeping the midsole durable for longer and high mileage runs.

The Fluidride is a combination of the SpEVA and the Super Solyte material. These are both integrated to the IGS system of the midsole, giving runners a new style of running in a more cushioned way. This system enhances the Asics Rearfoot and Forefoot Gel Cushioning system.

The upper of this Asics running shoe has the seamless construction that comprises the Sandwich Mesh and HotMelt overlays. This improvement provides added breathability as well as snug fit, support, and protection. The rearfoot upper is also designed with softer materials for added comfort.
