Saucony Triumph ISO 3 vs. 4 review

Saucony Triumph ISO 3 adds plushness, a secure fit, comfort, and flexibility to your long runs. Saucony Triumph ISO 4 increases comfort and the fit with a new midsole and outsole.

The Saucony Triumph ISO 4 is the updated version of the Saucony Triumph ISO 3, which is a neutral cushioning running shoe for runners who want a soft ride and who do not need a whole lot of stability and support.

ADVERTISEMENTS

The uppers of the Saucony Triumph ISO 4 The preceding link takes you to Amazon.com and the Saucony Triumph ISO 3 are similar in that they both come with engineered mesh that reduces the need for overlays, especially on the toe box.

The biggest change, however, has been to the ISOFIT overlays.

The Saucony Triumph ISO 3 The preceding link takes you to Amazon.com comes with semi-stitched-on overlays around the midfoot, while these overlays have been removed from the Saucony Triumph ISO 4 and replaced by no-sew overlays and mesh.

This means that there will be more of a stretch around the midfoot of the Saucony Triumph ISO 4 so that you can dial in the fit as you wish.

However, the removal of the stitched-on overlays reduces the amount of support you get around the midfoot of the Saucony Triumph ISO 4 compared to the Saucony Triumph ISO 3.

Both running shoes have a no-sew overlay on the toecap and a Support Frame at the back.

However, there has also been a change to the Support Frame, which has become a bit less sturdier on the Saucony Triumph ISO 4.

All in all, the changes that have been made to the upper of the Saucony Triumph ISO 4 should make it feel more comfortable than the Saucony Triumph ISO 3, but the upper of the Saucony Triumph ISO 3 is more supportive than that of the Saucony Triumph ISO 4.

Both the Saucony Triumph ISO 3 and the Saucony Triumph ISO 4 come with EVERUN cushioning in their midsoles.

But whereas the Saucony Triumph ISO 3 only has a topsole of this material, the Saucony Triumph ISO 4 implements it throughout its entire midsole.

This does not necessarily make the Saucony Triumph ISO 4 cushier than the Saucony Triumph ISO 3, though, because according to running shoe lab tests, the Saucony Triumph ISO 3 already delivered almost a maximum amount of cushioning in both the heel and the forefoot and to both men and women.

The amount of heel cushioning is just a tad less than the amount of forefoot cushioning.

Both the Saucony Triumph ISO 4 and the Saucony Triumph ISO 3 provide a good amount of ground contact under the midfoot, and this adds to the stability of the running shoes.

However, because they are neutral running shoes, you should not expect to get a whole lot of stabilty from them. They are generally on the average side.

The rubber outsoles of the Saucony Triumph ISO 3 and the Saucony Triumph ISO 4 differ somewhat from each other.

The Saucony Triumph ISO 3 provides an average amount of flexibility to women and is quite flexible for men.

This is mainly thanks to the wide and plentiful flex grooves in the forefoot of the Saucony Triumph ISO 3.

These flex grooves have more or less been removed from the outsole of the Saucony Triumph ISO 4 and replaced by vertical flex grooves instead.

The horizontal flex grooves in the forefoot of the Saucony Triumph ISO 4 are plentiful, but do not expose midsole material like in the outsole of the Saucony Triumph ISO 3.

This might impact the flexibility of the Saucony Triumph ISO 4 and reduce it a bit compared to the Saucony Triumph ISO 3.

Another change has been to the rubber pad just on the back and outside under the heel. This rubber under the Saucony Triumph ISO 4 is much less separated than the one under the Saucony Triumph ISO 3, and this could have a minor impact on the softness of your landing.

However, because both running shoes provide a good amount of ground contact and there is a good amount of separation between the rubber pods in the entire outsole, you should still be able to get smooth heel-to-toe transitions from either.

The women's version of the Saucony Triumph ISO 4 weighs approximately 9.4 oz (266 grams), and the Saucony Triumph ISO 3 for women weighs 8.7 oz (247 grams).

The men's versions of the shoes weigh 10.8 oz (306 grams) and 10.8 oz (306 grams), respectively, so they weigh about the same amount.

If you are a neutral runner who is looking for a soft and smooth ride from a running shoe, you could choose either the Saucony Triumph ISO 3 or the Saucony Triumph ISO 4.

The Saucony Triumph ISO 4 has a somewhat less supportive upper than the Saucony Triumph ISO 3 but might offer a bit more comfort and a more precise fit to runners.

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.
