Brooks Glycerin 15 vs. Brooks Transcend 4 review

Brooks Glycerin 15 is a premium cushioning shoe that offers a plush and soft running experience. Brooks Transcend 4 provides a very plush and comfortable ride with stability.

The Brooks Glycerin 15 and the Brooks Transcend 4 fall in two different categories of running shoes, with the Brooks Glycerin 15 being a neutral cushioning running shoe and the Brooks Transcend 4 a stability running shoe.

ADVERTISEMENTS

The uppers of the Brooks Glycerin 15 The preceding link takes you to Amazon.com and the Brooks Transcend 4 look very much alike because they both make use of 3D Fit Print overlays.

They also both have overlays running along the length of the upper. The difference is that the Brooks Glycerin 15 also has overlays running across the midfoot; these are absent in the Brooks Transcend 4 The preceding link takes you to Amazon.com.

Both running shoes come with a stitched-on toecap, but while the Brooks Glycerin 15 also has a stitched-on piece at the back for extra support, the Brooks Transcend 4 comes with an external heel counter that not only locks in the heel but also helps prevent your heel from rolling inward.

Basically, pronation control starts in the upper of the Brooks Transcend 4. The Brooks Glycerin 15 does not offer pronation control because it is meant to be worn by runners who do not need such support.

All in all, you should be able to get a comfortable fit from either the Brooks Transcend 4 or the Brooks Glycerin 15, but the Brooks Transcend 4 provides a bit more support at the back than the Brooks Glycerin 15 does.

The midsoles of the Brooks Glycerin 15 and the Brooks Transcend 4 consist of the same type of cushioning that is meant to deliver a very soft ride.

According to running shoe lab tests, both running shoes deliver almost a maximum amount of cushioning in the heel and in the forefoot and to both men and women, with the Brooks Transcend 4 being placed a tiny bit higher than the Brooks Glycerin 15.

The midsoles are also similar in that they provide a good amount of ground contact, especially under the midfoot.

Therefore, both the Brooks Glycerin 15 and the Brooks Transcend 4 have the potential to deliver smooth heel-to-toe transitions.

A good amount of ground contact also increases the stability of a running shoe, so it is not surprising that both running shoes offer an above average amount of stability.

Where the Brooks Transcend 4 and the Brooks Glycerin 15 differ in the midsole is in the fact that the Brooks Transcend 4 comes with Guide Rails at the upper edge of the midsole to help runners find their natural motion path.

The Brooks Transcend 4 does not implement a traditional method of pronation control by using a medial post in the midsole. This is perhaps why running shoe lab tests rate the Brooks Transcend 4 and the Brooks Glycerin 15 as being almost equally stable.

Do keep in mind, however, that the Brooks Transcend 4 was made for moderate overpronators and the Brooks Glycerin 15 for neutral runners.

The rubber outsoles of the two running shoes differ somewhat in layout, but both display a good amount of separation and have quite a bit of flex grooves in the forefoot.

In addition, the outsole seems to broaden a bit under the midfoot of the Brooks Transcend 4. This might be to increase the amount of stability in that area.

The Brooks Transcend 4 and the Brooks Glycerin 15 provide almost a similar amount of flexibility.

The Brooks Glycerin 15 is a bit more flexible than the Brooks Transcend 4 for women, with both delivering an average amount of stability.

For men, the Brooks Transcend 4 is a tiny bit more flexible than the Brooks Glycerin 15, and both deliver a slightly below average amount of flexibility.

The women's version of the Brooks Glycerin 15 weighs approximately 8.8 oz (249 grams), and the Brooks Transcend 4 for women also weighs 8.8 oz (249 grams).

The men's versions of the shoes weigh 10.7 oz (303 grams) and 10.9 oz (309 grams), respectively, with the Brooks Glycerin 15 being the lighter one.

If you are looking to get a very soft and smooth ride from a running shoe, you could choose either the Brooks Glycerin 15 or the Brooks Transcend 4 because they come very close to providing a similar running experience.

While they have been rated to provide almost a similar amount of stability, the Brooks Transcend 4 is the one that was built for overpronators and the Brooks Glycerin 15 for neutral runners, but judging from test results, either running shoe could be worn neutral runners.
