Cushioning

Heel stack

The Glycerin 20 has a mighty heel stack height of 37.1 mm which is about 4 mm thicker than the average. Actually, only 16% of our lab-tested road shoes went past 37 mm in their stack heights.

That's an immense amount of cushioning and impact protection on the road!

Drop

The heel-to-toe drop turned out to be even bigger than claimed by the brand. We measured it at 12.8 mm, while the officially stated drop is 10 mm.

This heel elevation is perfect for beginners and heel-striking runners. However, for those who expect 10 mm precisely, a higher drop could be an unpleasant surprise!

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

The best way to describe this Glycerin shoe is that it's the beast of comfort. We found the shoe's cushioning to be a major step up from the past versions. 

It's soft with a touch of bounce; it's definitely more fun to run in. Not to mention, it's not the type of plush that bottoms out.

Using our durometer, we found that the foam on the Glycerin 20 is on the softer end of the spectrum. At 20.0 HA, it is 20% softer than the average.

It's just the right fit. We found the Brooks GLycerin 20 to be comfortably snug and our medium-width feet never felt constricted in the shoe.

The fact the Glycerin 20 is 2 mm narrower than average didn't make it less comfortable. Our caliper shows 95.9 mm in the widest part of the forefoot.

Lacing

The laces on the zapatillas de running Brooks pronador talla 35.5 azules are a bit of a letdown. They tend to come undone mid-run which was never an issue with the past iterations.

Double-knotting is a must if you don't want to keep re-lacing them.

Stability

Lateral stability test

The Brooks Beast 20 delivers maximum support and generous cushioning at its lightest weight yet.

We believe that this is due to the shoe's moderately stiff build, semi-rigid heel counter, and wider-than-average platform.

Torsional rigidity

The zapatillas de running Brooks pronador talla 35.5 azules is not so easy to twist torsionally. In our manual assessment, we rated its torsional stiffness at 3. That is on a 1-5 scale where 5 is the stiffest.

We find it a very welcome touch of support for mildly pronating and tired feet.

The shoe also has an amply padded heel collar which has a medium level of stiffness. In our manual test, we rated it as 3 out of 5 (5 being the stiffest).

We found that it helps to hold the ankle a little better and more securely than the average neutral shoe.

Midsole width - forefoot

Last but not least, the Glycerin 20 has an extra-wide landing area!

Based on our caliper measurements, it is 4 mm wider than the average in the forefoot (117.4 mm).

The shoe's heel also flaunts a wider-than-average platform. At 94.2 mm, it is wider than the usual by 4 mm, just like the forefoot.

Because of its high stack and pretty thick outsole, the zapatillas de running Brooks pronador talla 35.5 azules loses a bit in the flexibility department.

However, based on our force gauge measurement, it still remains slightly more flexible than the average. It takes 8% less force to bend the Glycerin 20 to a 90-degree angle than it takes a road shoe on average.

Weight

The Glycerin 20 looks bulky with all the cushion it gets. However, on foot, it's the total opposite. It feels light and IS lighter than ever. 

Brooks-Glycerin-20-lightweight

Tipping the scale at 10.5 oz (297g) in a men's US size 9, the Glycerin is about half an ounce heavier than the shoes of its kind. For reference, the average weight of daily trainers with a heel stack of 37+ mm is 9.9 oz (281g).

See how easily the smoke passes through the fabric in our breathability test below. On a 1-5 scale, where 5 is the most breathable, this Brooks shoe gets a 4.

Durability

blue brooks shoes | Outsole hardness

Looking at our durometer measurement, we give a nod of approval to the shoe's outsole hardness. At 79.5 HC, it is just as hard as the other road shoe outsoles on average.

Harder rubbers typically take longer to wear out, so we anticipate at least 400 miles from this Brooks shoe.

Misc

Grip / Traction

Our test runs showed that the Glycerin 20 sticks well on pavement, gravel, and slick surfaces pretty well!

Tongue padding

Upon step-in, our feet were welcomed with plush padding from the heel and ankle collar. On top of this, the tongue remained cozy with its amply padded design. Even better, we felt like it stepped up the shoe's lockdown and security.

The tongue is indeed generously padded on the Glycerin 20. Our caliper shows that it is 7.8 mm thick, while the average for running shoes is 5.8 mm.

zapatillas de running Brooks pronador talla 35.5 azules vs. 19

To cut a long story short, the Glycerin 20 from Brooks is definitely a better version than the 19. The following changes helped to make it happen: 

  • blue brooks shoes: The new midsole compound amps up comfort even more. Even better, it sheds off a few grams. 
  • More pep: Apart from elevating comfort, the midsole also makes the Glycerin bouncy, making the ride a lot more enjoyable than before. 
  • zapatillas de running Brooks pie cavo minimalistas talla 37.5: In the outsole, there's plenty of rubber coverage. And for better grip, the flex grooves have also been revamped. 
  • Added comfort: Midsole aside, the upper is also more padded in the heel and the tongue. These do not only make the shoe cozier; they also better the support.
