Saucony Freedom ISO vs. Saucony Zealot ISO 3 review

Saucony Freedom ISO provides a soft, comfortable, and flexible ride to neutral runners. Saucony Zealot ISO 3 provides a soft ride and brings runners closer to a neutral plane.

The Saucony Freedom ISO and the Saucony Zealot ISO 3 are neutral cushioning running shoes that have a low heel-to-toe drop.

ADVERTISEMENTS

The uppers of both the Saucony Freedom ISO The preceding link takes you to Amazon.com and the Saucony Zealot ISO 3 The preceding link takes you to Amazon.com are very light and consist mostly of engineered mesh that provides some structure and support without having to use overlays.

The mesh can be pulled tight through the saddle of the Saucony Freedom ISO, while the Saucony Zealot ISO 3 comes with extra straps around the midfoot that can also be pulled tight via the laces.

Both running shoes are clearly geared towards providing runners with a lot of comfort through their uppers.

The Saucony Zealot ISO 3 implements some overlays at the back for additional support but only comes with a strip around the toecap at the front.

The Saucony Freedom ISO, on the other hand, comes with a no-sew overlay at the front but does not have overlays at the back.

Instead, the Saucony Freedom ISO has a sturdy Support Frame that locks in the heel and provides lots of support in that area.

All in all, the Saucony Zealot ISO 3 and the Saucony Freedom ISO provide a similar amount of support and comfort through their uppers, with perhaps the Saucony Freedom ISO providing a bit more support around the heel.

Both the Saucony Zealot ISO 3 and the Saucony Freedom ISO come with EVERUN cushioning in their midsoles, but whereas the Saucony Zealot ISO 3 only has a top layer of this material, the Saucony Freedom ISO has its entire midsole consisting of it.

However, this does not automatically make the Saucony Freedom ISO the cushier running shoe of the two, because running shoe lab tests show that the Saucony Zealot ISO 3 provides overall more cushioning than the Saucony Freedom ISO to both men and women.

The Saucony Zealot ISO 3 provides almost a maximum amount of heel and forefoot cushioning, while the Saucony Freedom ISO lies just a couple of notches below that.

The situation is similar for both men and women, so you should be able to get a soft ride from either running shoe, with the Saucony Zealot ISO 3 delivering the softest ride between the two.

Neither the Saucony Freedom ISO nor the Saucony Zealot ISO 3 is meant to provide a lot of stability and support, because they are both meant to be worn by neutral runners.

So not surprisingly, running shoe lab tests show that they both provide a moderate amount of stability and support, probably because they provide so much ground contact, which not only increases stability but also delivers smoother heel-to-toe transitions.

The main thing to remember about these two running shoes is that they have low heel-to-toe drops.

The heel-to-toe drop is about 4.9 mm for men and 4.7 mm for women in the Saucony Freedom ISO, while the same numbers are 6.5 mm and 5.1 mm, respectively, in the Saucony Zealot ISO 3.

Therefore, one could say that the Saucony Freedom ISO brings you closer to a neutral plane than the Saucony Zealot ISO 3.

It also brings you closer to the ground, because it sits lower on the ground than the Saucony Zealot ISO 3. About 2 to 4 mm lower.

The rubber outsoles of the two running shoes look a bit different, with the Saucony Freedom ISO having an all-in-one outsole.

The flex grooves are similar in the forefoot, although the Saucony Zealot ISO 3 has larger spacings.

Running shoe lab tests have found that both the Saucony Freedom ISO and the Saucony Zealot ISO 3 are very flexible running shoes, with the Saucony Freedom ISO being just a tiny bit more flexible than the Saucony Zealot ISO 3.

The women's version of the Saucony Freedom ISO weighs approximately 7.5 oz (213 grams), and the Saucony Zealot ISO 3 weighs approximately 7.4 oz (210 grams).

The men's versions of the shoes weigh 9.3 oz (264 grams) and 8.7 oz (247 grams), respectively, with the Saucony Zealot ISO 3 being the lighter one.

The Saucony Freedom ISO and the Saucony Zealot ISO 3 are very similar in what they provide to runners, with just a few minor differences.

If you are a neutral runner who is looking for a running shoe that is relatively light and that brings you closer to the ground and a neutral plane, you could choose either the Saucony Zealot ISO 3 or the Saucony Freedom ISO, thereby keeping in mind that the Saucony Freedom ISO has a lower profile height than the Saucony Zealot ISO 3.

And if you are also after a soft ride, the Saucony Zealot ISO 3 provides a bit more of a softer ride than the Saucony Freedom ISO.
