The ASICS GEL-Kayano 25 and the Brooks Ariel 18 / Brooks Beast 18 are stability running shoes for overpronators, but whereas the ASICS GEL-Kayano 25 is more for moderate overpronators, the Brooks Ariel 18 / Brooks Beast 18 can be worn by severe overpronators.

ADVERTISEMENTS

Therefore, there is not much competition going on between the ASICS GEL-Kayano 25 and the Brooks Ariel 18 The preceding link takes you to Amazon.com / Brooks Beast 18, but let us take a look at them anyway and compare them.

The uppers of the ASICS GEL-Kayano 25 The preceding link takes you to Amazon.com and the Brooks Ariel 18 / Brooks Beast 18 have the same goal in mind of providing lots of comfort.

The Brooks Ariel 18 / Brooks Beast 18 The preceding link takes you to Amazon.com does so by implementing no-sew overlays around the midfoot and around the toe box, while the ASICS GEL-Kayano 25 leaves most of its upper free from overlays and moves them into the running shoe where there is a network of underlays to provide support.

Therefore, the Brooks Ariel 18 / Brooks Beast 18 offers a more secure fit around the midfoot where overpronators tend to need the most support.

While the Brooks Ariel 18 / Brooks Beast 18 does not have any overlays on top of its toe box, it does have a stitched-on toecap and no-sew overlays running along the upper edge of the midsole around the toe box.

Because the ASICS GEL-Kayano 25 does not have any overlays at the sides of its toe box, it is less constricted than the Brooks Ariel 18 / Brooks Beast 18, although both running shoes tend to keep the bunion area clear so are good for runners who have big bunions.

Note that some underlays in the ASICS GEL-Kayano 25 might cross the bunion window, but they should not be that noticeable.

Both the Brooks Ariel 18 / Brooks Beast 18 and the ASICS GEL-Kayano 25 come with an external heel counter around the heel to lock it in and minimize heel rotation.

However, because the external heel counter of the ASICS GEL-Kayano 25 wraps the lower and upper part of the heel, it might be more suitable for prevention of heel rotation and for starting the process of pronation control right from within the upper.

The external heel counter of the Brooks Ariel 18 / Brooks Beast 18 is more suitable for providing a more secure heel fit.

However, when you take everything into consideration, the Brooks Ariel 18 / Brooks Beast 18 delivers much more support through its upper than the ASICS GEL-Kayano 25, which delivers a good amount of support around the heel and lightweight support elsewhere in its upper.

ADVERTISEMENTS

Both the ASICS GEL-Kayano 25 and the Brooks Ariel 18 / Brooks Beast 18 are meant to give overpronators a soft ride, but their midsoles are constructed differently.

The Brooks Ariel 18 / Brooks Beast 18 has one main layer of foam that is supposed to deliver lots of cushioning, and then on top of that, it comes with a full-length crash pad on the lateral side that is meant to deliver soft landings and smoother heel-to-toe transitions.

The ASICS GEL-Kayano 25 comes with one main layer of foam in its forefoot that gets thinner while it extends towards the heel. Then the ASICS GEL-Kayano 25 has a second, more responsive layer that runs from heel to midfoot with GEL cushioning between the two layers.

The ASICS GEL-Kayano 25 has been found to deliver a good amount of forefoot cushioning, but its heel could feel moderately cushioned to firm to some runners.

Because the midsole of the Brooks Ariel 18 / Brooks Beast 18 provides more ground contact than that of the ASICS GEL-Kayano 25, the former is more likely to provide smoother heel-to-toe transitions along with its full-length crash pad that also adds a bit more stability to the Brooks Ariel 18 / Brooks Beast 18.

Because the ASICS GEL-Kayano 25 and the Brooks Ariel 18 / Brooks Beast 18 are meant to provide support to overpronators, they come with a support system on the medial side of their midsoles.

The area of support is long in both running shoes, but the Brooks Ariel 18 / Brooks Beast 18 is the one that has its support go all the way up to the foot.

Both running shoes also come with a midfoot shank that differ slightly in what they provide.

The midfoot shank of the ASICS GEL-Kayano 25 connects the two sides of the midsole to deliver midfoot integrity and support, while the midfoot shank of the Brooks Ariel 18 / Brooks Beast 18 is located only on the medial side and hooks up into the medial post under the heel to reinforce it.

Therefore, you can expect to get a much stronger degree of pronation control from the Brooks Ariel 18 / Brooks Beast 18 than you would get from the ASICS GEL-Kayano 25.

When you look at the outsoles, the outsole of the Brooks Ariel 18 / Brooks Beast 18 appears to be much broader than that of the ASICS GEL-Kayano 25, because the Brooks Ariel 18 / Brooks Beast 18 uses a straighter platform.

It also has more separation and segmentation, which are good for absorbing and dissipating shock, and therefore giving you a smoother ride.

The outsole of the ASICS GEL-Kayano 25 comes with a vertical flex groove that is meant to help with gait efficiency. Such a feature is missing in the outsole of the Brooks Ariel 18 / Brooks Beast 18.

Both the Brooks Ariel 18 / Brooks Beast 18 and the ASICS GEL-Kayano 25 have a minimum amount of flex grooves in the forefoot, so it is not surprising that the ASICS GEL-Kayano 25 has been found to be a stiff running shoe with the good amount of forefoot cushioning that it delivers, and the same can be expected of the Brooks Ariel 18 / Brooks Beast 18.

The Brooks Ariel 18 / Brooks Beast 18 is a much heavier running shoe than the ASICS GEL-Kayano 25 and therefore suitable for heavier runners or runners that have a larger build.

If you are a moderate overpronator who is looking for a good amount of stability and support that is not over the top, you could look into the ASICS GEL-Kayano 25. The ASICS GEL-Kayano 25 is a running shoe that was created to give runners a luxurious ride.

If you are a severe overpronator or a big runner who has flat or large feet, you should look into the Brooks Ariel 18 / Brooks Beast 18 before you look into the ASICS GEL-Kayano 25, because the latter might not offer enough pronation control and support for your needs.

Note: The weight of a running shoe depends on the size of the running shoe, so any weights mentioned in this review may differ from the weight of the running shoe you choose to wear. Running shoes of the same size were compared for this review.
