The Mizuno Wave Rider 21 and the Saucony Triumph ISO 4 are neutral cushioning running shoes for runners who do not need much stability and support.

ADVERTISEMENTS

The uppers of the Mizuno Wave Rider 21 The preceding link takes you to Amazon.com and the Saucony Triumph ISO 4 have been kept quite open with a minimum amount of overlays.

However, the Mizuno Wave Rider 21 has more stitches in its upper than the Saucony Triumph ISO 4.

The Saucony Triumph ISO 4 The preceding link takes you to Amazon.com comes with an ISOFIT upper that provides a custom fit around the midfoot.

The Mizuno Wave Rider 21 has the Mizuno logo connecting the saddle to the midsole and some underlays around the midfoot to really give you a secure fit around the midfoot.

The forefoot of the Mizuno Wave Rider 21 has been kept free from overlays, while there are some running on the medial side of the forefoot of the Saucony Triumph ISO 4 and the Saucony logo comes far forward on the lateral side.

Therefore, the Mizuno Wave Rider 21 is more likely to deliver unobstructed comfort in the toe box.

While the Mizuno Wave Rider 21 has a stitched-on overlay at the back for extra support, the Saucony Triumph ISO 4 comes with a Support Frame that wraps around the upper part of the heel.

However, mesh is still exposed at the back of the Saucony Triumph ISO 4, so in the end, it might deliver as much support behind the heel as the Mizuno Wave Rider 21 does.

All in all, both the Saucony Triumph ISO 4 and the Mizuno Wave Rider 21 deliver an adequate amount of support to neutral runners through their uppers, but the Saucony Triumph ISO 4 might be able to deliver a more custom fit, while the Mizuno Wave Rider 21 could provide a secure fit and slightly more comfort in the toe box.

The midsoles of the Mizuno Wave Rider 21 and the Saucony Triumph ISO 4 differ in that the Mizuno Wave Rider 21 comes with a Wave Plate that delivers shock absorption as well as support under the midfoot.

The Saucony Triumph ISO 4 has a more all-in-one midsole and a top layer of extra cushioning for heel-to-toe softness.

Lab tests have found that the Saucony Triumph ISO 4 has a cushier forefoot than the Mizuno Wave Rider 21 and that the Mizuno Wave Rider 21 has a cushier heel than the Saucony Triumph ISO 4 for both men and women.

This means that the Mizuno Wave Rider 21 might feel more responsive than the Saucony Triumph ISO 4 and is slightly better for heel-strikers.

However, because both running shoes deliver an above average amount of heel and forefoot cushioning, they can both deliver a soft ride to runners.

The Mizuno Wave Rider 21 also has a higher heel-to-toe drop than the Saucony Triumph ISO 4 so might feel more like a performance running shoe.

The outsoles of the two running shoes look quite different, with the Mizuno Wave Rider 21 having a traditional forefoot and heel separation.

The Mizuno Wave Rider 21 has two horizontal flex grooves in the forefoot, and the Saucony Triumph ISO 4 has horizontal cuts in the rubber but not deep horizontal flex grooves. This does not benefit flexibility.
