NEW! Brooks Glycerin 13 vs. Brooks Glycerin 14

The Brooks Glycerin 13 is the updated version of the Brooks Glycerin 12, which is a top-of-the-line neutral cushioning running shoe from Brooks.

ADVERTISEMENTS

The Brooks Glycerin 13 The preceding link takes you to Amazon.com looks very much like the Brooks Glycerin 12 thanks to the overlays that Brooks has maintained pretty much the same.

The overlays in the upper of the Brooks Glycerin 13 are still no-sew and have been printed on the shoe.

While the overlays in the Brooks Glycerin 12 run similarly to those in the Brooks Glycerin 13, Brooks has added a couple of extra 3-D Print overlays on top of the toe box.

The overlays running at the sides of the toe box of the Brooks Glycerin 13 are also somewhat broader than those on the Brooks Glycerin 12.

What's important, however, is that the sturdy overlays with some stitches around the midfoot where you typically need the most support, have remained largely intact except for the fact that they have a slightly different design.

The backs of the shoes are also similar, but again look slightly different due to the new design of the Brooks Glycerin 13.

All in all, you should expect a similar amount of support and comfort from the upper of the Brooks Glycerin 13 as you got from the Brooks Glycerin 12, since the changes in the upper have been mostly cosmetic.

The Brooks Glycerin 13 still has a Super DNA midsole just like the Brooks Glycerin 12 that provides 25% more cushioning than the Brooks BioMoGo DNA midsole as found in the Brooks Ghost.

There are some minor differences in the thickness of the midsoles of the Brooks Glycerin 12 and the Brooks Glycerin 13, and the heel-to-toe drop is about 1.3 mm less in the women's Brooks Glycerin 13 and 1.1 mm less in the men's Brooks Glycerin 13.

This means that the Brooks Glycerin 13 brings you closer to a neutral plane than the Brooks Glycerin 12. A 1 mm difference is pretty insignificant, though, so the running experience in the Brooks Glycerin 13 should be about the same as in the Brooks Glycerin 12.

Running shoe lab tests have shown that the Brooks Glycerin 12 is more cushy than the Brooks Glycerin 13 in both the heel and the forefoot. For women, the Brooks Glycerin 12 is on average about 20% more cushy than the Brooks Glycerin 13.

For men, the Brooks Glycerin 12 turns out to be about 16% more cushy than the Brooks Glycerin 13.

The rest of the features that were present in the Brooks Glycerin 12 are still present in the Brooks Glycerin 13, such as a rounded heel to provide better joint alignment and stress reduction, a segmented crash pad and good ground contact for a smooth heel-to-toe transition, and ideal pressure zones to disperse shock.

While the outsole of the Brooks Glycerin 13 has not changed much compared to that of the Brooks Glycerin 12, Brooks has filled in a small piece in the center of the midfoot to provide full ground contact there as well as added a bit more segmentation to the rubber pieces at the sides under the midfoot.

This should help with a much smoother transition than in the Brooks Glycerin 12 as well as make the Brooks Glycerin 13 a bit more stable compared to the Brooks Glycerin 12.

The minor cuts in the rubber lugs in the forefoot are also slightly different than in the Brooks Glycerin 12. The Brooks Glycerin 13 has more squarish cuts in the small rubber lugs and round cuts in the lugs at the sides.

These changes should not have a huge effect on your stride. However, running shoe lab tests have shown that the Brooks Glycerin 13 is a little bit stiffer than the Brooks Glycerin 12 for women, but that it is much more flexible than the Brooks Glycerin 12 for men.

The women's version of the Brooks Glycerin 13 weighs approximately 8.9 oz (252 grams), while the Brooks Glycerin 12 for women weighs approximately 8.7 oz (247 grams).

The men's version of the Brooks Glycerin 13 weighs about 11.0 oz (312 grams), and the Brooks Glycerin 12 for men also weighs about 11.0 oz (312 grams).

The Brooks Glycerin 12 was already a good running shoe for heavier runners who do not need much stability or support but are rather looking for lots of cushioning in a running shoe.

This has not changed in the Brooks Glycerin 13. The main difference is that the Brooks Glycerin 13 may feel just a bit firmer than the Brooks Glycerin 12 under your foot, but with that you also gain a bit more stability.

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.
