Saucony Guide 8 vs. Saucony Triumph ISO review

Saucony Guide 8 strikes a good balance between cushioning, guidance, and support. Saucony Triumph ISO provides a plush and comfortable ride for the long runs of neutral runners.

NEW! Saucony Guide 9 vs. Saucony Triumph ISO 2 and Saucony Guide 10 vs. Saucony Triumph ISO 3

The Saucony Guide 8 and the Saucony Triumph ISO fall in two different categories of running shoes with the Saucony Guide 8 being a stability running shoe and the Saucony Triumph ISO a neutral cushioning running shoe.

Both the Saucony Guide 8 and the Saucony Triumph ISO provide a good amount of support around the midfoot in the upper.

However, because the overlays used in the Saucony Triumph ISO cover a larger area and really hug the foot, the Saucony Triumph ISO can be see as the one providing more support around the midfoot.

This does not mean, though, that the Saucony Guide 8 is not supportive, since it has a good amount of sturdy stitched-on overlays on the medial side where support is generally needed most.

The overlays of the Saucony Triumph ISO tend to come far forward, while those on the Saucony Guide 8 open up the forefoot a bit more, so might also feel more comfortable in the forefoot area compared to the Saucony Triumph ISO.

Both running shoes provide an adequate amount of support behind the heel.

The Saucony Triumph ISO implements a midsole that is supposed to provide 20% more cushioning than the midsole of the Saucony Guide 8.

The midsole of the Saucony Triumph ISO is also more thicker in both the heel and the forefoot than the Saucony Guide 8 for both men and women, which should deliver a protective ride.

With all this, one would assume that the Saucony Triumph ISO is more cushy than the Saucony Guide 8, but running shoe lab tests show some results that might surprise you.

For women, the Saucony Guide 8 turns out to have a slightly more cushy heel than the Saucony Triumph ISO, but it does not win in the forefoot department. However, the forefoot of the Saucony Guide 8 is still way above average.

For men, the Saucony Triumph ISO turns out to be an overall super cushy running shoe, so beats the Saucony Guide 8, especially in the amount of heel cushioning, which is on the average side.

Both running shoes have a crash pad under the heel that runs till the midfoot to join the forefoot, so should be able to provide you with a soft landing and a smooth transition to toe-off thereafter.

The big difference in the midsole can be found on the medial side where the Saucony Guide 8 has a medial post to control overpronation and stop your foot from rolling too far inward.

The Saucony Triumph ISO does not have such a post, since it is meant to be worn by neutral runners who do not need such kind of support.

The Saucony Guide 8 also has a piece of plastic hooking into the medial post for reinforcement. This makes the running shoe not completely touch the ground on the medial side under the arch.

This is in contrast to the Saucony Triumph ISO, which provides full ground contact under the arch. This adds a little bit of stability to the running shoe and increases its potential for delivering a smoother ride.

The rubber outsoles of the two Saucony running shoes look very similar, especially in the forefoot where they both have a fan-shaped pattern.

However, the Saucony Guide 8 has more segmentation and flex grooves than the Saucony Triumph ISO, which tends to have slightly larger rubber compartments.

Larger rubber compartments are good for the durability of the running shoe, but a lack of flex grooves can cause a shoe to be stiff.

Running shoe lab tests confirm that the Saucony Triumph ISO is quite stiff. However, the Saucony Guide 8 is also stiff for men. It is the women's version of the Saucony Guide 8 that is a little bit more flexible than the Saucony Triumph ISO for women.

The women's version of the Saucony Guide 8 weighs approximately 8.4 oz (238 grams) and the Saucony Triumph ISO for women weighs 8.4 oz (238 grams).

The men's versions of the running shoes weigh 10.1 oz (286 grams) and 10.1 oz (286 grams), respectively.

So the two running shoes weigh about the same amount for both men and women.

If you are a moderate overpronator looking for a running shoe that offers a moderately soft ride and provides a lot of stability and support in addition to a secure fit, then the Saucony Guide 8 might be worth looking into.

And if you are a neutral runner looking for a very plush ride in a running shoe with a very supportive upper, then the Saucony Triumph ISO might 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.
