The Brooks Glycerin 15 and the Saucony Triumph ISO 4 are neutral cushioning running shoes that can be worn by runners who do not need much stability and support and who are a bit on the heavy side.

ADVERTISEMENTS

The uppers of the Brooks Glycerin 15 The preceding link takes you to Amazon.com and the Saucony Triumph ISO 4 differ quite a bit in construction.

The Saucony Triumph ISO 4 The preceding link takes you to Amazon.com comes with a couple of no-sew overlays around the midfoot and at the front of the running shoe but consists mostly of mesh that can be pulled tight through the laces.

The Brooks Glycerin 15, on the other hand, has many more overlays than the Saucony Triumph ISO 4. They run across the midfoot as well as along the length of the entire running shoe.

These overlays are no-sew 3D-printed overlays, but the Brooks Glycerin 15 also comes with a stitched-on piece at the front and at the back for durability and additional support.

All in all, you should be able to get a comfortable yet secure fit from both running shoes, but the fit might be a bit more streamlined from heel-to-toe in the Brooks Glycerin 15 than in the Saucony Triumph ISO 4.

The midsoles of the Saucony Triumph ISO 4 and the Brooks Glycerin 15 also differ quite a bit.

The Saucony Triumph ISO 4 comes with an additional layer of cushioning on top of its midsole, while the midsole of the Brooks Glycerin 15 consists mostly of one main layer of Brooks' best-cushioned midsole material.

The midsole of the Brooks Glycerin 15 is well segmented, which adds to the stability of the running shoe, and both running shoes provide a good amount of ground contact for stability and smoother heel-to-toe transitions.

Running shoe lab tests have found that both the Brooks Glycerin 15 and the Saucony Triumph ISO 4 have a cushy forefoot.

However, men will get a bit more forefoot cushioning from the Brooks Glycerin 15, while the Saucony Triumph ISO 4 provides more forefoot cushioning to women.

The Brooks Glycerin 15 wins in the heel cushioning department, although both running shoes have a cushy heel, and the difference in heel cushioning is very small for women.

The conclusion is that you should be able to get a soft ride from either running shoe, but men will get a much softer ride in the Brooks Glycerin 15 than in the Saucony Triumph ISO 4.

The differences between the women's running shoes are minor, with the Saucony Triumph ISO 4 having a slight advantage over the Brooks Glycerin 15 where forefoot cushioning is concerned.

Neither the Saucony Triumph ISO 4 nor the Brooks Glycerin 15 is meant to provide stability and support, but the Brooks Glycerin 15 is still rated by running shoe lab tests as being more stable than the Saucony Triumph ISO 4, probably due to the segmentation in the midsole.

The rubber outsoles of the two running shoes differ quite a bit, with the Saucony Triumph ISO 4 having vertical flex grooves in its forefoot and the Brooks Glycerin 15 quite a few horizontal flex grooves.

Both running shoes display a good amount of separation and segmentation for shock absorption and dissipation.

The Brooks Glycerin 15 has been found to be flexible for women, but somewhat stiff for men.

However, this is nothing compared to the Saucony Triumph ISO 4, which has been found by running shoe lab tests to be quite stiff for both men and women.

The women's version of the Brooks Glycerin 15 weighs approximately 8.8 oz (249 grams), and the Saucony Triumph ISO 4 for women weighs 9.5 oz (270 grams).

The men's versions of the shoes weigh 10.7 oz (303 grams) and 11.3 oz (320 grams), respectively, with the Brooks Glycerin 15 being the 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 Saucony Triumph ISO 4 or the Brooks Glycerin 15.

While the Brooks Glycerin 15 and the Saucony Triumph ISO 4 look different and are from two different manufacturers, they tend to provide very similar things to runners, so making a choice between them will not be easy.

The Brooks Glycerin 15 is lighter and seems to be more favorable for men who are looking for a very soft ride.

The Saucony Triumph ISO 4 is good for women who are looking for an overall very soft ride but has the disadvantage of being stiffer and heavier than the Brooks Glycerin 15.
