Saucony Triumph ISO vs. Saucony Kinvara 5 review

Saucony Triumph ISO provides a super soft and comfortable ride for long runs. Saucony Kinvara 5 is good for uptempo runs by runners who want a light shoe on their feet.

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 5 are both neutral cushioning running shoes with the main difference that the Saucony Kinvara 5 is for performance runs and the Saucony Triumph ISO for longer runs.

ADVERTISEMENTS

The upper of the Saucony Kinvara 5 has been kept light with no-sew overlays and thin Flexfilm welded-on overlays, while that of the Saucony Triumph ISO has thicker no-sew overlays and also some stitches.

A stitch-free environment is a more comfortable environment, but generally also a less supportive environment.

However, the Saucony Kinvara 5 locks down the foot on the platform by having a band that runs under the overlays and that can be adjusted in the saddle, thereby making it almost as secure as the Saucony Triumph ISO where midfoot wrapping is concerned.

At the back of the Saucony Triumph ISO there is a support frame that really cups the heel well to lock down the heel on the platform. The Saucony Kinvara 5 does not have such a support frame.

The overlays that hug the midfoot in the Saucony Triumph ISO run far forward towards the toes, while the more supportive no-sew overlays have been pulled back on the Saucony Kinvara 5.

So you can expect a pretty comfortable feeling in the forefoot area of the Saucony Kinvara 5 compared to the Saucony Triumph ISO, despite the Saucony Triumph ISO being the one that offers a slightly more secure fit.

The Saucony Triumph ISO and the Saucony Kinvara 5 offer heel-to-toe cushioning through their midsoles, but of a different kind.

The Saucony Kinvara 5 tends to provide cushioning that is firmish and responsive, while still being soft enough for runners to get a comfortable ride.

The Saucony Triumph ISO on the other hand throws a lot of plush cushioning at you. It also has the updated version of the midsole of the Saucony Kinvara 5, which provides 20% more cushioning.

However, when you compare lab test results, the Saucony Kinvara 5 does not lack a lot behind the Saucony Triumph ISO. In fact, it comes surprisingly close the amount of cushioning provided by the Saucony Triumph ISO, especially for women.

But when you look at the overall cushioning profile, the Saucony Triumph ISO turns out to be a super cushy running shoe, especially for men where the amount of cushioning is to the max.

Both running shoes are not meant to provide any kind of stability and support, since they are meant to be worn by neutral runners. However, both running shoes provide a good amount of ground contact, which should add to their stability and their potential of providing you with smooth transitions from heel-strike to toe-off.

They both also come with a crash pad under the heel, although the crash pad of the Saucony Triumph ISO is more heavy-duty than that of the Saucony Kinvara 5.

The biggest difference between the Saucony Triumph ISO and the Saucony Kinvara 5 can be found in the outsole where the Saucony Kinvara 5 has a minimal amount of durable rubber and the Saucony Triumph ISO comes with tons of it.

The Saucony Kinvara 5 is all about performance, so the running shoe has been kept as light as possible. The durable rubber pods under the Saucony Kinvara 5 have only been added to high-wear areas and under the forefoot.

The flex grooves under the Saucony Kinvara 5 also differ a lot from those under the Saucony Triumph ISO and tend to encourage flexibility in the shoe, since they are more linear and run from side to side.

And indeed, running shoe lab tests confirm that the Saucony Kinvara 5 is a super flexible running shoe (for both men and women) compared to the Saucony Triumph ISO, which is quite stiff.

The women's version of the Saucony Kinvara 5 weighs approximately 6.3 oz (178 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.

If you are a neutral runner looking to feel fast in a running shoe that can also go the distance by providing you with enough comfort and cushioning, then the Saucony Kinvara is definitely worth looking into.

And if you are looking for a super cushy and smooth ride from a running shoe that offers lots of protection from the road and comfort for long runs, then the Saucony Triumph ISO could be the one for you.

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.
