Zapatillas Brooks Running Adrenaline GTS 21 para Mujer Negro Rosa | Brooks Glycerin 20 review

We encourage you not to pass up on the Brooks Glycerin 20 if you want a: 

• comfy and great-value option for both beginners and running veterans  
• Пальто шерстяное brooks brothers

At £160, it may not be the most affordable running shoe. However, if you want a shoe that screams comfort and durability, the Glycerin 20 is one of the best on the market that we have ever tested. 

If you're a sucker for responsiveness and speed, you can skip the Brooks Glycerin 20. For a smoother, speed-oriented ride, you can go for the  Footwear BROOKS Adrenaline Gts 21 110349 1D 418 Blue instead. 

Those who want a set of trusty laces plus the energetic ride, go for the Boots STUART WEITZMAN Brooks YL96069 Cabernet Ghent.

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!

The forefoot, on the other hand, is a normcore. Our calliper shows a moderate 24.3 mm of stack height under the toes which is nearly the same as the average.

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!

The best way to describe this Glycerin shoe is that it's the beast of comfort. We Rucksack 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 Rucksack 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. 

The shoe's foam also doesn't get much firmer in cold temperatures. After 20 minutes in the freezer, it only firmed up by 23%. Some shoes get up to 60% firmer in the same test. 

To accompany the shoe's above-average midsole, Brooks also used a thicker-than-average insole for the Glycerin 20. Our calliper shows 5.5 mm which is a millimetre thicker than the average.

It's just the right fit. We Rucksack 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.

The laces on the Brooks Glycerin 20 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.

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

The Brooks Glycerin 20 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 Rucksack that it helps to hold the ankle a little better and more securely than the average neutral shoe.

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

Based on our calliper 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.

But if you do have flat feet and/or overpronation, we recommend going for the shoe's stability version, the zapatillas de running Brooks mixta minimalistas talla 44.5. Brooks Wide Little Kid Big Kid.

Because of its high stack and pretty thick outsole, the Brooks Glycerin 20 loses a bit in the flexibility department.

However, based on our force gauge measurement, it still remains slightly more flexible than the average. It still takes less force to bend the Glycerin 20 to a 30-degree angle (12.9N) than it takes a road shoe on average.

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. 

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).

During warm days, we Rucksack that the shoe remains light and breezy. The upper doesn't restrict air and our feet didn't feel toasty at all. We can readily recommend the shoe for summer runs.

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.

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.

The Glycerin 20 also has a good amount of rubber that will help the grip last a while. Using our calliper, we measured the outsole to be 3.5 mm thick, which is the average thickness for road running shoes.

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

Upon step-in, our feet were welcomed with plush padding from the heel and ankle collar. On top of this, the tongue remained cosy 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 calliper shows that it is 7.8 mm thick, while the average for running shoes is 5.8 mm.

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: 

• Brooks Homme Chaussures de course: The new midsole compound amps up comfort even more. Even better, it sheds off a few grammes. 
• More pep: Apart from elevating comfort, the midsole also makes the Glycerin bouncy, making the ride a lot more enjoyable than before. 
• Sturdier and stickier: 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 cosier; they also better the support.

Apart from the standard Brooks Glycerin 20, there are three other versions of Glycerin 20, including: 

• Brooks Glycerin 20 StealthFit - It is a sleeker, snugger version of the standard Glycerin 20. 
• zapatillas de running Brooks hombre negras - It is the Glycerin 20's Go-To-Stability version, perfect for mild to moderate overpronators (whose feet roll inward excessively). 
• zapatillas de running Brooks hombre negras StealthFit - Like the Glycerin 20 StealthFit, it has a more foot-conforming wrap than the regular GTS version.
