ADVERTISEMENTS

The Brooks Glycerin 15 The preceding link takes you to Amazon.com is more for the heavier runner who is also looking for some stability, while the Brooks Launch 4 The preceding link takes you to Amazon.com is for the lighter runner who wants to feel light and fast.

The uppers of both running shoes have been kept light with mesh and no-sew overlays.

However, the Brooks Glycerin 15 has more overlays covering the forefoot than the Brooks Launch 4 does.

This allows the Brooks Glycerin 15 to deliver a somewhat tighter and more custom fit in the forefoot.

Both the Brooks Launch 4 and the Brooks Glycerin 15 have a good amount of overlays around the midfoot, so your feet should remain firmly on the running platform.

They also both come with a stitched-on toecap at the front for durability.

The Brooks Glycerin 15 also comes with a stitched-on piece at the back, while the Brooks Launch 4 continues to wrap the no-sew overlays around the heel.

Therefore, the back of the Brooks Glycerin 15 might be a bit more durable, but the amount of support delivered might be similar to that of the Brooks Launch 4.

All in all, the Brooks Glycerin 15 delivers an overall more secure and custom fit, while the Brooks Launch 4 increases the amount of comfort you get in the forefoot area.

The Brooks Launch 4 and the Brooks Glycerin 15 use two different types of cushioning in their midsoles.

The Brooks Launch 4 implements Brooks' standard midsole material, while the Brooks Glycerin 15 implements a midsole material that is supposed to deliver 20% more cushioning than the standard one.

The difference in cushioning is clearly visible in running shoe lab test results, which show that the Brooks Glycerin 15 delivers almost a maximum amount of cushioning in both the heel and the forefoot, while the Brooks Launch 4 lags behind.

Women should be able to get a moderate amount of forefoot cushioning from the Brooks Launch 4, but the heel might feel firm.

The amount of forefoot cushioning and heel cushioning increases a bit for men, but the heel might still feel a bit firm to men also.

Therefore, if you are looking for a very soft ride, the Brooks Glycerin 15 would be the one to deliver that. The Brooks Glycerin 15 would also be more suitable for heel-strikers.

Both running shoes provide a good amount of ground contact, which adds a bit to the stability of the running shoes and also helps them provide smoother heel-to-toe transitions.

The Brooks Launch 4 has rubber under the midfoot in the form of an X for faster heel-to-transitions.

The midsole of the Brooks Glycerin 15 seems more segmented, though, and together with the fact that its base does not narrow as much under the midfoot as the one of the Brooks Launch 4 does, helps it to be a more stable running shoe, according to running shoe lab test results.

The Brooks Launch 4 provides a below average amount of stability, while the Brooks Glycerin 15 shoots up above average.

Both the Brooks Launch 4 and the Brooks Glycerin 15 have a good amount of flex grooves in the forefoot, with the Brooks Glycerin 15 having slightly more.

The outsole of the Brooks Glycerin 15 is also a bit more separated, but the Brooks Launch 4 is still the more flexible one for both men and women, according to running shoe lab tests.

The Brooks Glycerin 15 is moderately flexible for women and somewhat stiff for men, but the Brooks Launch 4 is very flexible for both men and women.

The women's version of the Brooks Glycerin 15 weighs approximately 8.8 oz (249 grams), and the Brooks Launch 4 for women weighs approximately 7.7 oz (218 grams).

The men's versions of the shoes weigh 10.7 oz (303 grams) and 9.2 oz (261 grams), respectively, with the Brooks Launch 4 being the lighter one.

If you neutral runner who is looking for a very soft and stable ride from a running shoe, the Brooks Glycerin 15 is definitely worth considering.

And if you are a neutral runner who is looking for a running shoe that could make you feel light and fast, you may want to look into the Brooks Launch 4.
