ADVERTISEMENTS

However, while they are similar in that respect, they were still created with different goals in mind. The Saucony Kinvara 9 The preceding link takes you to Amazon.com is more a race day running shoe, while the Saucony Zealot ISO 3 can be used for long-haul training.

The uppers of the Saucony Kinvara 9 and the Saucony Zealot ISO 3 The preceding link takes you to Amazon.com differ in that the Saucony Zealot ISO 3 comes with an ISOFIT upper, while the Saucony Kinvara 9 does not.

The Saucony Kinvara 9 has thin no-sew overlays running across its midfoot to provide support in that area.

The Saucony Zealot ISO 3 comes with straps that can be pulled tight through the laces, so the Saucony Zealot ISO 3 is a bit more adjustable than the Saucony Kinvara 9.

Both running shoes have a toe box that is quite open, but the Saucony Zealot ISO 3 is probably the one that provides more freedom at the front due to its lack of overlays on the toe box.

The Saucony Kinvara 9 and the Saucony Zealot ISO 3 also differ at the back, where the Saucony Kinvara 9 has a woven heel area and the Saucony Zealot ISO 3 has a molded heel that provides a more lockdown fit.

Therefore, the Saucony Zealot ISO 3 delivers more support at the back, although the woven area around the heel of the Saucony Kinvara 9 comes far forward to connect well to the midfoot and the saddle, so it does offer a good amount of lightweight support.

All in all, you should be able to get enough support as a neutral runner from the upper of either running shoe, but the Saucony Zealot ISO 3 is the one that delivers a more personalized fit with a good amount of support behind the heel and a good amount of comfort in the toe box.

The upper of the Saucony Kinvara 9 has been kept light with enough support to keep your foot on the running platform.

The midsoles of the Saucony Zealot ISO 3 and the Saucony Kinvara 9 are similar in that they both have an EVERUN topsole construction for heel-to-toe softness.

Both running shoes also provide a good amount of ground contact, which should benefit the smoothness of your ride as well as add some stability to your runs.

The midsoles of the Saucony Kinvara 9 and the Saucony Zealot ISO 3 are also similar in that they both have a relatively low heel-to-toe drop.

Saucony lists both running shoes as having a heel-to-toe drop of 4 mm, but lab tests have found the heel-to-toe drop of the Saucony Zealot ISO 3 to lie between 5 and 6.5 mm, while that of the Saucony Kinvara 9 is about 6 mm.

However, the Saucony Zealot ISO 3 sits a bit higher off the ground under the heel and under the forefoot (about 2 to 3 mm), so while both running shoes will bring you closer to a neutral plane, the Saucony Kinvara 9 is the one that also brings you overall closer to the ground.

Because the Saucony Kinvara 9 and the Saucony Zealot ISO 3 are meant to be worn by neutral runners, they do not come with any devices to control pronation.

However, they do deliver a moderate amount of stability with the Saucony Kinvara 9 being rated slightly higher than the Saucony Zealot ISO 3 probably because it sits a bit lower on the ground.

This is in contrast with how Saucony places the Saucony Kinvara 9 and the Saucony Zealot ISO 3. Saucony considers the Saucony Zealot ISO 3 to be a bit more stable than the Saucony Kinvara 9 probably because the Saucony Zealot ISO 3 has a somewhat more supportive upper.

The Saucony Zealot ISO 3 has wide flex grooves in the forefoot that benefit the flexibility of the running shoe, because it has been found to deliver a moderate amount of flexibility to both men and women, while the Saucony Kinvara 9 has been found to be stiff for both genders.

The women's version of the Saucony Zealot ISO 3 weighs approximately 7.4 oz (210 grams), and the Saucony Kinvara 9 for women weighs about 6.5 oz (184 grams).
