Brooks Glycerin 15 vs. Saucony Triumph ISO 3 review

Brooks Glycerin 15 is a premium cushioning shoe that offers a plush and soft running experience. Saucony Triumph ISO 3 delivers plushness, a secure fit, comfort, and flexibility.

The Brooks Glycerin 15 and the Saucony Triumph ISO 3 fall in the same category of neutral cushioning running shoes for runners who do not need much stability and support.

ADVERTISEMENTS

The uppers of the Brooks Glycerin 15 The preceding link takes you to Amazon.com and the Saucony Triumph ISO 3 differ quite a bit due to the fact that the Saucony Triumph ISO 3 has stitched-on overlays around the midfoot while the Brooks Glycerin 15 does not.

The overlays on the Saucony Triumph ISO 3 The preceding link takes you to Amazon.com have been moved back far enough to open up the forefoot for comfort.

The Brooks Glycerin 15 has no-sew overlays running across the midfoot but also along the length of the entire upper.

Because the Saucony Triumph ISO 3 uses engineered mesh instead of overlays on the toe box, it might provide more room to big bunions than the Brooks Glycerin 15 would.

The Brooks Glycerin 15 comes with stitches at the front and the back of the running shoe to increase durability and support.

The Saucony Triumph ISO 3 does not have stitches at the front, but at the back, it has a Support Frame that wraps around the heel to increase the amount of support there.

All in all, the Saucony Triumph ISO 3 might provide a more secure fit around the midfoot, and the Brooks Glycerin 15 might provide a more custom fit throughout its entire upper.

The midsoles of the Brooks Glycerin 15 and the Saucony Triumph ISO 3 are similar in that they provide full ground contact under the midfoot.

Therefore, both have the potential to deliver smooth heel-to-toe transitions.

Another thing that the Saucony Triumph ISO 3 and the Brooks Glycerin 15 have in common is that they are both geared toward providing runners with a very soft ride.

This is also evident from running shoe lab tests, which show that both the Saucony Triumph ISO 3 and the Brooks Glycerin 15 deliver an almost maximum amount of cushioning to both men and women.

There are minor differences to be noted, with the Saucony Triumph ISO 3 providing slightly more forefoot cushioning than the Brooks Glycerin 15, and the Brooks Glycerin 15 providing slightly more heel cushioning than the Saucony Triumph ISO 3.

But the differences are too small to be noticeable; both running shoes should feel very plush on your feet.

Neither the Saucony Triumph ISO 3 nor the Brooks Glycerin 15 come with a device to control overpronation, because they are running shoes for neutral runners, not overpronators.

However, they still score high in the stability department. According to running shoe lab tests, both running shoes deliver an above average amount of stability, with the Brooks Glycerin 15 being a bit more stable than the Saucony Triumph ISO 3.

The rubber outsoles of the two running shoes differ quite a bit in their patterns, but both have a good amount of flex grooves in the forefoot and separation elsewhere. Both of these things should benefit the flexibility of the running shoes.

Running shoe lab tests rate the Saucony Triumph ISO 3 for men to be very flexible and much more flexible than the Brooks Glycerin 15 for men.

On the other hand, women should be able to get a bit more flexibility from the Brooks Glycerin 15 than they would from the Saucony Triumph ISO 3.

The women's version of the Brooks Glycerin 15 weighs approximately 8.8 oz (249 grams), and the Saucony Triumph ISO 3 for women weighs 8.7 oz (247 grams).

The men's versions of the shoes weigh 10.7 oz (303 grams) and 10.8 oz (306 grams), respectively, with the Brooks Glycerin 15 being the slightly lighter one.

If you are a neutral runner who is looking for a very soft and smooth ride from a running shoe, you could choose either the Brooks Glycerin 15 or the Saucony Triumph ISO 3, because they do not differ much in that respect.

However, the Saucony Triumph ISO 3 might provide a slightly more secure fit around the midfoot and comfort in the toe box, while the Brooks Glycerin 15 might provide a bit more stability.
