ASICS GEL-Kayano 21 vs. Saucony Hurricane ISO 2 review

ASICS GEL-Kayano 21 offers a very plush and comfortable ride to moderate overpronators. Saucony Hurricane ISO 2 offers lots of stability, support, and cushioning to overpronators.

NEW! ASICS GEL-Kayano 23 vs. Saucony Hurricane ISO 2 and ASICS GEL-Kayano 22 vs. Saucony Hurricane ISO 2

The ASICS GEL-Kayano 21 and the Saucony Hurricane ISO 2 are stability running shoes that can be worn by runners who moderately overpronate.

ADVERTISEMENTS

Both the ASICS GEL-Kayano 21 and the Saucony Hurricane ISO 2 come with very supportive uppers.

The Saucony Hurricane ISO 2 The preceding link takes you to Amazon.com has ISOFIT overlays wrapping the midfoot around socklike mesh. These overlays extend toward the back of the shoe to really give you a good hold.

The ASICS GEL-Kayano 21 has sturdy stiched-on overlays wrapping the midfoot. These overlays also extend toward the back of the shoe but provide slightly less coverage than those on the Saucony Hurricane ISO 2.

And then at the back of the shoes, both the Saucony Hurricane ISO 2 and the ASICS GEL-kayano 21 come with an external heel counter to add more support in that area.

The main difference between the upper of the Saucony Hurricane ISO 2 and that of the ASICS GEL-Kayano 21 can be found in the forefoot area, where the Saucony Hurricane ISO 2 has less overlays than the ASICS GEL-Kayano 21.

The ASICS GEL-Kayano 21 comes with smaller and thinner FluidFit overlays that run between the sturdier overlays to really give you a close-to-foot fit.

The toe box of the Saucony Hurricane ISO 2 is more open and free in that respect and has very light welded-on overlays at its sides.

Overall, you should be able to get a good amount of support from the upper of either running shoe.

Both the ASICS GEL-Kayano 21 and the Saucony Hurricane ISO 2 are meant to be very cushy running shoes.

The ASICS GEL-Kayano 21 achieves this through two layers of midsole foam with GEL cushioning between those layers.

The Saucony Hurricane ISO 2 has one main layer with a layer of softer foam just under the sockliner and as an insert in the heel on the lateral side of the midsole.

Running shoe lab tests have shown that both running shoes are almost equally cushy and very cushy in both the heel and the forefoot for women. The Saucony Hurricane ISO 2 has just a tiny edge on the ASICS GEL-Kayano 21.

For men, the ASICS GEL-Kayano 21 is the overall more cushy one and the Saucony Hurricane ISO 2 lags a bit behind in the amount of heel cushioning it provides; it has a very cushy forefoot, though, and above average cushioning in the heel.

Both the ASICS GEL-Kayano 21 and the Saucony Hurricane ISO 2 are meant to provide support to overpronators but they do so in different degrees.

The Saucony Hurricane ISO 2 has a long piece of firmer foam on the medial side of the midsole that helps stop your foot from rolling too far inward. This post runs pretty high and is filled out at the bottom under the arch with rubber.

The ASICS GEL-Kayano 21 also has a support system in place on the medial side that consists of firmer foam and a midfoot shank that connects the lateral to the medial side.

It is unclear how high the support system goes, although it is clear that it does not go all the way to the top due to the softer layer of foam closest to the foot.

Running shoe lab tests indicate that the Saucony Hurricane ISO 2 is the more stable running shoe of the two. This is also partly due to the fact that the Saucony Hurricane ISO 2 provides more ground contact than the ASICS GEL-Kayano 21, especially under the midfoot.

The latter also increases the potential of the Saucony Hurricane ISO 2 of delivering a much smoother ride from heel-strike to toe-off.

The rubber outsoles of the two running look quite different with the ASICS GEL-Kayano 21 having larger slabs of rubber under it than the Saucony Hurricane ISO 2.

The Saucony Hurricane ISO 2 is more segmented and also has a different pattern for its flex grooves in the forefoot.

According the running shoe lab tests, the ASICS GEL-Kayano 21 is the more flexible running shoe of the two with the Saucony Hurricane ISO 2 falling on the stiffer end of the spectrum for both genders.

The women's version of the Saucony Hurricane ISO 2 weighs approximately 9.0 oz (255 grams) and the ASICS GEL-Kayano 21 for women weighs 9.5 oz (269 grams).

The men's versions of shoes weigh 10.9 oz (309 grams) and 11.3 oz (320 grams), respectively, with the Saucony Hurricane ISO 2 being the lighter one.

If you are a moderate overpronator who is looking for a running shoe that provides a very soft ride and a secure fit with a durable outsole, then the ASICS GEL-Kayano 21 is worth looking into.

But if you need more stability of support and are looking for a somewhat lighter running shoe that can deliver a smooth ride and a secure fit, then the Saucony Hurricane ISO 2 might be the one for you.

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.
