NEW! ASICS GEL-Kayano 24 vs. Saucony Hurricane ISO 3 and ASICS GEL-Kayano 25 vs. Saucony Hurricane ISO 4

The ASICS GEL-Kayano 23 and the Saucony Hurricane ISO 2 are stability running shoes that can be worn by runners who moderately overpronate.


However, just by looking at the running shoes, one can already see the difference in amount of support provided; the Saucony Hurricane ISO 2 looks more sturdy and supportive.

Nonetheless, let's take a look at how they compare against each other.

The uppers of the ASICS GEL-Kayano 23 The preceding link takes you to and the Saucony Hurricane ISO 2 The preceding link takes you to are similar in that they both come with an external heel counter at the back for additional support, but they differ in the type of overlays used.

The ASICS GEL-Kayano 23 comes with a minimum amount of stitches in its upper, it uses very light no-sew overlays around the midfoot, and the rest of the upper has mesh with structure to provide a bit of support.

The Saucony Hurricane ISO 2, on the other hand, comes with quite a bit of sturdy stitched-on overlays around the midfoot in the form of ISOFIT. These provide a wrap around the midfoot and the heel, and give a large amount of support in that area.

And then it has lighter no-sew overlays running over the toe box to reduce the amount of possible irritation.

So overall, the Saucony Hurricane ISO 2 is expected to provide a more secure fit than the ASICS GEL-Kayano 23, but the ASICS GEL-Kayano 23 might feel more comfortable and loose, especially around the bunion window.

Both the ASICS GEL-Kayano 23 and the Saucony Hurricane ISO 2 are meant to provide lots of cushioning to overpronators.

While the materials and the composition of their midsoles differ quite a bit, they tend to achieve what they are after.

However, according to running shoe lab tests, the Saucony Hurricane ISO 2 turns out to be the more cushy running shoe of the two in both the heel and the forefoot.

The difference in heel cushioning is not that large in the two running shoes. Women should experience a very cushy heel in either running shoe, while men will get a bit less cushioning but still enough that their ride should still feel on average soft.

But it is in the forefoot cushioning department where the Saucony Hurricane ISO 2 excels and provides way more than the ASICS GEL-Kayano 23 for both men and women.

Note that forefoot cushioning can get in the way of going faster, so it is not always a good thing. It all depends on what you prefer and what your running style is.


Both the Saucony Hurricane ISO 2 and the ASICS GEL-Kayano 23 are meant to provide support to overpronators, but because the ASICS GEL-Kayano 23 can also be worn by neutral runners (according to ASICS), it provides a moderate amount of support and stability.

This is also evident from running shoe lab tests, which place the Saucony Hurricane ISO 2 high up in the range of stability provided.

The latter is probably due to the fact that the Saucony Hurricane ISO 2 has a very long medial post to control overpronation and provides more ground contact than the ASICS GEL-Kayano 23.

The ground contact does not only increase the stability of the running shoe a bit but also the smoothness of your heel-to-toe transitions.

However, where the ASICS GEL-Kayano 23 excels is in the amount of flexibility it provides to both men and women. According to running shoe lab tests, the Saucony Hurricane ISO 2 is quite stiff for both genders.

This stiffness may be appreciated by heavier runners who can handle it and generally find that it increases their stability.

The outsoles of the two running shoes look quite different due to the fact that the Saucony Hurricane ISO 2 does not have a midfoot shank like the ASICS GEL-Kayano 23.

The layout of the rubber compartments is also quite different, but both running shoes display a good amount of separation, which should help dissipate and absorb shock.

The women's version of the ASICS GEL-Kayano 23 weighs approximately 9.4 oz (266 grams), and the Saucony Hurricane ISO 2 for women weighs 9.0 oz (255 grams).

The men's versions of the shoes weigh 11.5 oz (326 grams) and 10.9 oz (309 grams), respectively, with the Saucony Hurricane ISO 2 being the lighter one.

If you are a moderate overpronator who is looking for a soft and comfortable ride, you could go with either the ASICS GEL-Kayano 23 or the Saucony Hurricane ISO 2.

However, if you want an increased amount of stability and support in addition to a softer and smoother ride at a lighter weight, you may want to look into the Saucony Hurricane ISO 2 more than the ASICS GEL-Kayano 23.
