The Asics Gel Cumulus model is one of the pillars of the Asics running shoe range. This new version, the twentieth, takes up the recipe which made the success of the previous models with a few additional improvements. First of all, the shoe has lost weight and now drops below 300 grams to be in line with its direct competitors like the Nike Pegasus. FlyteFoam technology has also been added to make the cushioning even more comfortable. Thus, despite a relatively thin sole (23 mm and 22 mm, respectively for the men’s and women’s models), the Cumulus offers responsive cushioning that absorbs shocks well. In comparison, the Cumulus 20 are thus lighter and more dynamic than the Nimbus while offering fairly similar cushioning. For the rest, as is customary with Asics, the shoes are robust and have a very pleasant light and flexible upper. In summary, the Asics Gel Cumulus 20 are good, very comfortable road shoes that will delight runners looking for an efficient standard model.



  • The Gel Cumulus 20 use two types of rubber in the outsole.
  • First of all, the ultra-resistant rubber developed by the Japanese brand, Asics High Abrasion Rubber (AHAR) , equips the parts likely to be damaged quickly due to abrasion. So the heel is equipped with it, for example.
  • Next, DuraSponge technology equips the rest of the outsole. It is a more flexible material made from blown rubber for more lightness and flexibility during the stride, especially at the level of the front of the foot.


  • The FluidRide technology , which consists of Solyte and SpEVA , is the main cushioning technology of the Asics Gel Cumulus 20. It allows a comfortable and light cushioning by absorbing shocks well.
  • In addition, the main improvement compared to the previous model, the FlyteFoam technology now equips the midsole of the Asics Gel Cumulus in addition to FluidRide.
  • This foam developed by Asics uses organic fibers to provide comfortable and responsive cushioning. According to the brand, FlyteFoam foam is 55% lighter than traditional foams.
  • On the other hand, Gel technology , which translates into silicone-based parts, equips the heel and front of the shoes for more effective shock absorption.
  • Like many other Asics models, the Cumulus feature Impact Guidance System (IGS) . With its Guidance Line , IGS aims to adjust the shoe’s center of pressure to help the athlete achieve a more efficient stride.
  • Finally, an OrthoLite sockliner provides a light layer of support and additional cushioning to the shoe. It is also antimicrobial to help maintain a healthy interior.

Upper part (upper)

  • The upper uses a stretchable Jacquard mesh able to expand in all directions for complete freedom of movement.
  • The structure is seamless and light while being reinforced in certain strategic places.
  • In addition, the Discrete Eyelet technology allows you to tighten the laces thanks to a main eyelet.
  • Finally, a reflective strip is present at the heel to be more visible at night.
