ADVERTISEMENTS

The uppers of the Saucony Zealot ISO 2 The preceding link takes you to Amazon.com and the Saucony Kinvara 8 differ quite a bit due to the use of ISOFIT overlays in the upper of the Saucony Zealot ISO 2.

These overlays contain stitches and wrap the midfoot to give you a good amount of support around the midfoot.

The Saucony Kinvara 8 The preceding link takes you to Amazon.com implements lighter and much thinner no-sew overlays to keep the running shoe light and comfortable.

In addition, it has sturdier pieces on the medial side of the heel and the lateral side of the midfoot to box your foot and keep it in place.

The Saucony Zealot ISO 2 continues with stitched-on overlays around the heel to provide extra support behind the heel.

The Saucony Zealot ISO 2 has light no-sew overlays around the toe box and provides overall less room to bunions than the Saucony Kinvara 8 does.

Overall, you should be able to get a more secure fit from the Saucony Zealot ISO 2, but the Saucony Kinvara 8 keeps things lighter and more comfortable while still providing enough support to keep you on the running platform.

Both the Saucony Zealot ISO 2 and the Saucony Kinvara 8 come with EVERUN cushioning at the top of the midsole and have a landing zone or crash pad under the heel to soften your landings.

In terms of cushioning, Saucony places the Saucony Zealot ISO 2 in the plush category, while the Saucony Kinvara 8 falls in the firm and responsive category.

However, when you look at the results from running shoe lab tests, the cushioning profiles of the two running shoes do not differ that much.

Both the Saucony Kinvara 8 and the Saucony Zealot ISO 2 provide a large amount of forefoot cushioning, and the amount of heel cushioning lies far above average.

However, the Saucony Kinvara 8 seems to provide a tiny bit more heel and forefoot cushioning than the Saucony Zealot ISO 2. The differences are barely noticeable, though.

So whether you run in the Saucony Kinvara 8 or the Saucony Zealot ISO 2, you should be able to get a soft ride.

Both the Saucony Kinvara 8 and the Saucony Zealot ISO 2 have a relatively low heel-to-toe drop.

For men, this heel-to-toe drop is 6.7 mm in the Saucony Zealot ISO 2 and 5.6 mm in the Saucony Kinvara 8. For women, these numbers are 5.0 mm and 5.5 mm, respectively.

Men tend to get a slightly thicker midsole in both the heel and the forefoot from the Saucony Zealot ISO 2, while the differences in midsole thickness are very small for women, but the Saucony Zealot ISO 2 sits a tiny bit higher off the ground than the Saucony Kinvara 8.

So overall, the Saucony Kinvara 8 brings you a bit closer to the ground than the Saucony Zealot ISO 2.

One big difference between the Saucony Zealot ISO 2 and the Saucony Kinvara 8 can be found in the outsole, where the Saucony Zealot ISO 2 has more rubber than the Saucony Kinvara 8 so can be considered to be a bit more durable.

The Saucony Kinvara 8 has rubber only in high-wear areas to keep the weight of the running shoe down so that you can go faster.

The flex groove pattern is pretty similar in the forefoot, and running shoe lab tests show minimal differences between the flexibility of the running shoes for both men and women.

Both the Saucony Zealot ISO 2 and the Saucony Kinvara 8 are very flexible running shoes, according to running shoe lab tests.

The women's version of the Saucony Kinvara 8 weighs approximately 6.8 oz (193 grams) and the Saucony Zealot ISO 2 for women weighs 8.4 oz (238 grams).

The men's versions of the shoes weigh 8.0 oz (227 grams) and 9.7 oz (275 grams), respectively, with the Saucony Kinvara 8 being the lighter one.

The Saucony Kinvara 8 and the Saucony Zealot ISO 2 have a lot in common, but two main differences are that the Saucony Zealot ISO 2 provides a more secure fit, while the Saucony Kinvara 8 is lighter.

So if you are a neutral runner who is looking for a very soft ride, you can choose either the Saucony Zealot ISO 2 or the Saucony Kinvara 8.

However, if you are also looking to go faster, you may want to consider the Saucony Kinvara 8 before looking into the Saucony Zealot ISO 2.
