The ASICS GEL-Cumulus 20 and the ASICS GEL-Kayano 25 fall in two different categories of running shoes, with the ASICS GEL-Cumulus 20 being a neutral running shoe and the ASICS GEL-Kayano 25 a stability running shoe.

ADVERTISEMENTS

Prior to the ASICS GEL-Kayano 25 The preceding link takes you to Amazon.com, the ASICS GEL-Kayano used to be suggested for neutral runners and overpronators, which made it more comparable to the ASICS GEL-Cumulus, but when the ASICS GEL-Kayano 25 was introduced, this changed.

Therefore, the ASICS GEL-Cumulus 20 The preceding link takes you to Amazon.com and the ASICS GEL-Kayano 25 are less comparable than their previous versions would have been, although the ASICS GEL-Cumulus is a more basic running shoe than the ASICS GEL-Kayano.

However, they still display some similarities, so let us take a look at them.

The uppers of the ASICS GEL-Kayano 25 and the ASICS GEL-Cumulus 20 are similar in that they have mesh and a forefoot that is quite open.

The ASICS GEL-Cumulus 20 comes with no-sew overlays around the midfoot in the form of the ASICS logo, which connects the saddle to the midsole to offer a good amount of support around the midfoot.

The ASICS GEL-Kayano 25 does not come with overlays, although the ASICS logo does keep some of the mesh together on the lateral side.

Instead, the ASICS GEL-Kayano 25 has moved its overlays to inside the running shoe, where it comes with an internal fit system of underlays.

Therefore, while not visible, the ASICS GEL-Kayano 25 might deliver an overall closer-to-foot fit than the ASICS GEL-Cumulus 20.

What is visible, however, is the fact that the back of the ASICS GEL-Kayano 25 is more closed than that of the ASICS GEL-Cumulus 20, because it comes with an external heel counter that wraps around your heel to lock it in.

Therefore, the ASICS GEL-Kayano 25 delivers much more support around the heel than the ASICS GEL-Cumulus 20 does.

All in all, both the ASICS GEL-Cumulus 20 and the ASICS GEL-Kayano 25 should feel comfortable on your feet, with the ASICS GEL-Cumulus 20 delivering an adequate amount of support as a neutral running shoe, and the ASICS GEL-Kayano 25 lots of support around the heel and comfort elsewhere.

The midsoles of the ASICS GEL-Kayano 25 and the ASICS GEL-Cumulus 20 are similar in that they come with visible GEL cushioning in the heel that is meant to soften your landings.

They both also have two layers of foam under the heel, but whereas the ASICS GEL-Cumulus 20 keeps these two layers also under the midfoot and the forefoot, the ASICS GEL-Kayano 25 has only the softer top layer of foam running all the way from heel to toe.

The more responsive and somewhat firmer layer of foam under the heel runs till the midfoot.

The ASICS GEL-Cumulus 20 also has a more responsive layer of foam as its bottom layer, so it also delivers heel-to-toe softness with its top layer while allowing your ride to feel more responsive with the bottom layer.

Lab tests have found that having a more responsive layer at the bottom, does not affect the amount of cushioning men get from the ASICS GEL-Cumulus 20 as much as it does for women.

According to lab tests, men can get an overall soft ride from the ASICS GEL-Cumulus 20, but women get a more moderate amount of heel cushioning and the forefoot of the ASICS GEL-Cumulus 20 could feel firm to some female runners.

While the bottom layer of foam under the heel of the ASICS GEL-Kayano 25 does contribute to it being a bit more supportive, it does affect the amount of heel cushioning delivered by the ASICS GEL-Kayano 25.

While the ASICS GEL-Kayano 25 has a cushy forefoot for both men and women, the amount of heel cushioning it delivers is more on the moderate to firm side.

Because women get an extra 3 mm of height under their heels to take stress of their Achilles, they also tend to get a bit more heel cushioning than men do from the ASICS GEL-Kayano 25.

When you compare the two running shoes with each other, men would get an overall softer ride in the ASICS GEL-Cumulus 20 and women in the ASICS GEL-Kayano 25, although the difference between the amount of heel cushioning women get would not be that big.

The ASICS GEL-Kayano 25 also has a higher heel-to-toe drop than the ASICS GEL-Cumulus 20 for both men and women.

While the difference in midsole thickness under the heel is not that large for men, the ASICS GEL-Cumulus 20 gives them slightly more foam under the forefoot. Women get a slightly thicker midsole under the heel and the forefoot of the ASICS GEL-Kayano 25.

The main differences between the midsoles of the ASICS GEL-Cumulus 20 and the ASICS GEL-Kayano 25 are that the ASICS GEL-Cumulus 20 provides more ground contact under the midfoot than the ASICS GEL-Kayano 25, and the ASICS GEL-Kayano 25 comes with a support system on the medial side of the midsole and a midfoot shank under the midfoot.

Therefore, while the ASICS GEL-Cumulus 20 does provide some stability with its full ground contact, the ASICS GEL-Kayano 25 is the one that would deliver more support with its support system in its midsole and its external heel counter in its upper.

The ASICS GEL-Cumulus 20 is more likely to deliver smoother heel-to-toe transitions, though.

The outsoles of both the ASICS GEL-Kayano 25 and the ASICS GEL-Cumulus 20 come with a vertical flex groove that is meant to help with gait efficiency, and they look like typical ASICS outsoles with large areas of rubber and a few flex grooves in the forefoot.

The main noticeable difference can be found in the area under the midfoot where the ASICS GEL-Kayano 25 has a midfoot shank and the ASICS GEL-Cumulus 20 does not.

Both the ASICS GEL-Kayano 25 and the ASICS GEL-Cumulus 20 have been found to be stiff running shoes for both men and women, but the ASICS GEL-Kayano 25 might feel a bit more flexible than the ASICS GEL-Cumulus 20 for men.

The ASICS GEL-Cumulus 20 is lighter than the ASICS GEL-Kayano 25 for both and women.

Making a decision between the ASICS GEL-Cumulus 20 and the ASICS GEL-Kayano 25 should not be that difficult, because they are meant to be worn by two different types of runners.

If you are a neutral runner, the ASICS GEL-Cumulus 20 was made with your needs in mind, and if you are a moderate overpronator, the ASICS GEL-Kayano 25 could give you a good amount of support.
