NEW! Saucony Triumph ISO 2 vs. Saucony Kinvara 7 and Saucony Triumph ISO 3 vs. Saucony Kinvara 7 and Saucony Triumph ISO 3 vs. Saucony Kinvara 8

The Saucony Triumph ISO and the Saucony Kinvara 6 are both neutral cushioning running shoes with the main difference that the Saucony Kinvara 6 is for performance runs and the Saucony Triumph ISO for longer runs.


Differences start in the upper where the Saucony Triumph ISO has broad overlays hugging the midfoot around a softer bed of socklike mesh. These overlays have some stitches in them at the front and back.

The Saucony Kinvara 6 The preceding link takes you to, on the other hand, has a seamless upper with very light welded-on overlays.

Because the no-sew overlays on the Saucony Kinvara 6 have been kept very light, the Saucony Kinvara 6 comes with bands on the medial and lateral side that allow you to really strap your foot in.

Therefore, you can expect to get a good amount of support around the midfoot from both running shoes, but more so from the Saucony Triumph ISO than from the Saucony Kinvara 6.

The midsoles of the Saucony Triumph ISO and the Saucony Kinvara 6 provide heel-to-toe cushioning.

However, the Saucony Triumph ISO uses midsole material that is supposed to deliver more cushioning than that of the Saucony Kinvara 6.

In addition, the Saucony Triumph ISO has an overall thicker midsole, so it sits higher off the ground than the Saucony Kinvara 6.

This does not automatically make the Saucony Triumph ISO outcushion the Saucony Kinvara, though.

Running shoe lab tests have shown that Saucony Triumph ISO provides more cushioning than the Saucony Kinvara 6 in both the heel and the forefoot for men. The difference is not huge, though.

However, for women, both the Saucony Kinvara 6 and the Saucony Triumph ISO have an equal amount of heel cushioning, and the forefoot cushioning of the Saucony Triumph ISO is just a notch more than that of the Saucony Kinvara 6.

Saucony also says that the type of cushioning of the Saucony Kinvara 6 is firm and responsive, while that of the Saucony Triumph ISO is plush.

Both the Saucony Triumph ISO and the Saucony Kinvara 6 provide full ground contact under the midfoot, which adds a touch of stability to the running shoes.

This, together with good segmentation in the outsole, allows both running shoes to deliver a smooth ride from heel-strike to toe-off.

The Saucony Kinvara 6 has less rubber in its outsole than the Saucony Triumph ISO, therefore making the Saucony Triumph ISO a more durable running shoe.

The layout of the rubber in the outsole of the Saucony Triumph ISO is not favorable for flexibility, though, and due to the large amount of forefoot cushioning provided by the Saucony Triumph ISO, it turns out to be a pretty stiff running shoe for both men and women.

The Saucony Kinvara 6, on the other hand, is measured through running shoe lab tests to be somewhat flexible for men and very flexible for women.

The women's version of the Saucony Kinvara 6 weighs approximately 6.5 oz (184 grams) and the Saucony Triumph ISO for women weighs 8.4 oz (238 grams).

The men's versions of the shoes weigh 7.8 oz (221 grams) and 10.1 oz (286 grams), respectively, with the Saucony Kinvara 6 being the lightest one.

If you are a neutral runner who is looking for a very soft ride, the Saucony Triumph ISO may suit you better than the Saucony Kinvara 6.

And if you are looking for a more responsive ride, the Saucony Kinvara 6 would be the one to look further into.
