Saucony Zealot ISO 2 vs. Saucony Zealot ISO review

Saucony Zealot ISO provides a smooth ride with a very cushy forefoot and a low heel-to-toe drop. Saucony Zealot ISO 2 provides an overall soft and smooth ride to neutral runners.

The Saucony Zealot ISO 2 is the updated version of the Saucony Zealot ISO, which is a neutral cushioning running shoe that brings runners closer to a neutral plane.

ADVERTISEMENTS

The upper of the Saucony Zealot ISO 2 The preceding link takes you to Amazon.com is very similar to that of the Saucony Zealot ISO with just a few minor tweaks.

First off, both the Saucony Zealot ISO The preceding link takes you to Amazon.com and the Saucony Zealot ISO 2 come with ISOFIT overlays that wrap the midfoot well around socklike mesh.

However, the ISOFIT overlays on the Saucony Zealot ISO 2 are less wide, meaning that they stop before reaching the bottom of the saddle, thereby opening up the forefoot a bit more for comfort.

The overlays on the Saucony Zealot ISO go further toward the forefoot so may feel a bit tighter in that area than the overlays on the Saucony Zealot ISO 2.

Another difference is that the Saucony Zealot ISO 2 has less overlays on the toe box itself. The no-sew overlays line the sides of the toe box instead of being placed directly on top like on the Saucony Zealot ISO.

One final change is that the Support Frame at the back of the Saucony Zealot ISO has been changed on the Saucony Zealot ISO 2 to be mostly overlays with stitches. However, you should still be able to get a good amount of support behind the heel.

All in all, you can expect to get a similar amount of support from the Saucony Zealot ISO 2 as you do from the Saucony Zealot ISO with the main difference being that the Saucony Zealot ISO 2 may feel a bit more comfortable in the forefoot area.

Both the Saucony Zealot ISO and the Saucony Zealot ISO 2 are meant to be plush running shoes. And according to charts from Saucony, the Saucony Zealot ISO is more plush than the Saucony Zealot ISO 2.

However, running shoe lab tests paint a different picture. According to running shoe lab tests, the Saucony Zealot ISO 2 is overall more cushy than the Saucony Zealot ISO, especially in the heel.

Both the Saucony Zealot ISO and the Saucony Zealot ISO 2 offer a lot of forefoot cushioning to both men and women, with the Saucony Zealot ISO 2 offering just a tiny bit more than the Saucony Zealot ISO.

And while the Saucony Zealot ISO offers above average heel cushioning to both men and women, the amount offered by the Saucony Zealot ISO 2 far exceeds that.

All in all, the Saucony Zealot ISO 2 displays a better balance between forefoot and heel cushioning.

This might be due to the EVERUN topsole cushioning that has been added to the Saucony Zealot ISO 2 and that is missing in the Saucony Zealot ISO.

Other than the cushioning profile, the Saucony Zealot ISO 2 brings women closer to the ground by having a somewhat thinner midsole (about 2 mm) and a 1.5 mm less heel-to-toe drop.

For men, the differences between the midsole heights and heel-to-toe drops are minimal.

Both running shoes provide a good amount of ground contact and come with a crash pad under the heel that connects well to the forefoot at the midfoot to give you a smooth transition from heel-strike to toe-off.

One last difference between the Saucony Zealot ISO 2 and the Saucony Zealot ISO can be found in the outsole, where the flex groove pattern has been changed.

Both running shoes provide a good amount of separation between their rubber compartments in the outsole, which should benefit the smoothness of your ride.

But running shoe lab tests show that the new outsole configuration of the Saucony Zealot ISO 2 really works in making it a very flexible running shoe.

So while the Saucony Zealot ISO might feel stiff to some, the Saucony Zealot ISO 2 should feel pretty flexible to both men and women.

The women's version of the Saucony Zealot ISO weighs approximately 7.2 oz (204 grams), and the Saucony Zealot ISO 2 for women weighs 8.4 oz (238 grams).

The men's versions of the shoes weigh 8.5 oz (241 grams) and 9.7 oz (275 grams), respectively, with the Saucony Zealot ISO being the lighter one.

Except for putting on a bit of weight, the Saucony Zealot ISO 2 is a very nice update of the Saucony Zealot ISO.

If you are a neutral runner who does not need stability but are rather looking for a good amount of cushioning and comfort in a running shoe, you may want to look into the Saucony Zealot ISO 2.

There is no need to stay on the Saucony Zealot ISO if you have been running in it unless you are looking for a lighter running shoe that is somewhat stiffer and does not go overboard with the amount of heel cushioning that it provides.

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.
