Introduction
The Brooks Glycerin 21 represents a significant stride in the evolution of Brooks’ acclaimed Glycerin series, well-known for its plush cushioning and exceptional comfort it has forged a long line of avid supporters, and rightly so. With its latest iteration, Brooks continues to innovate while maintaining the core attributes that loyalists have come to expect from this line. This review delves into the various aspects of the Brooks Glycerin 21, evaluating its performance, comfort, durability, and overall value.
First Impressions
Upon unboxing, the Brooks Glycerin 21 exudes a sense of premium quality. The shoe’s design, with its sleek aesthetic and contemporary colour palette, immediately catches the eye. The initial step-in comfort is notable, with the shoe wrapping snugly around the foot, offering a reassuring and supportive fit.
Upper
The upper of the Glycerin 21 features a luxurious, padded construction with a smooth lining, offering a seamless experience that eliminates the possibility of irritation or hot spots. The new knitted upper, softer to the touch than its predecessor, provides enhanced stretchability and foot conformity, albeit at the cost of slightly reduced breathability.
The padded, non-gusseted tongue stays in place thanks to a lace loop, reducing tongue slide. However, the new oval laces feel less premium than the flat laces found in the previous version. The toe box, wider than in the Glycerin 20, adds to the comfort, especially for runners with wider feet.
We find the Brooks Glycerin 21 although still true to fit, is slightly narrower than its predecessor but can also be found in a wide fitting for those that notice it.
Sole Unit
The sole unit of the Glycerin 21 sees significant updates, including lateral side rails in the forefoot and midfoot areas similar to the GTS Glycerin 21. These additions aim to improve stability, though their impact might be subtle for some runners.
The Glycerin 21’s DNA Loft v3 midsole, while cushioned, offers a firmer ride compared to some of its max-cushioned counterparts such as the Brooks Ghost Max. This characteristic makes it ideal for runners who prefer a more stable, less squishy platform.
The outsole design has been revamped, with less rubber on the midfoot for weight reduction and more segmentation in the forefoot for increased flexibility. The rubber lugs are durable and provide reliable traction, though they perform average on wet surfaces.
We have noticed that the exposed midsole seems to be made of a highly durable material, although not noted directly by Brooks as a feature, it looks to be long-lasting and after some aggressive test runs, is free from scuffs and scratches.
Performance and Comfort
In action, following true form, the Brooks Glycerin 21 shines as a daily trainer suitable for a variety of runs, especially long distances. Its cushioning, though not overly soft, provides a balanced ride, making it comfortable for extended periods. The shoe’s construction offers a stable and protective experience, which is particularly beneficial for heavier runners or those who prefer a firmer underfoot feel.
Despite its cushioning, the Glycerin 21 lacks the bouncy, energetic feel some runners might seek in a max-cushioned shoe, however, that is not to the shoe’s disadvantage. This aspect confines its best use to slower, relaxed runs rather than fast-paced workouts. The lack of a pronounced forefoot rocker also contributes to a flatter ride, though the increased flexibility in this version enhances the overall feel.
Durability and Quality
Brooks’ reputation for quality is upheld in the Glycerin 21. The robust construction of the upper and the durable outsole rubber ensures that the shoe can withstand significant mileage without showing signs of early wear. The midsole foam retains its form and function over time, providing consistent performance run after run.
Value and Price Point
Priced at £165, the Brooks Glycerin 21 sits at the higher end of the running shoe market. However, its durability, quality construction, and the level of comfort it offers justify the price, especially for runners who prioritize these aspects in their footwear.
How does it compare?
The max-cushioning neutral road market is seeing some tough competition lately and we are loving it. The most notable comparisons would be the new Brooks Ghost Max and the Saucony Triumph 21.

Final Thoughts
Long-standing advocates of the Glycerin range won’t be disappointed. The Brooks Glycerin 21 is a solid choice for runners seeking a reliable, well-cushioned, and stable daily trainer.
Its improvements over the previous version, particularly in terms of upper comfort and sole unit updates, make it a worthy investment for both Glycerin enthusiasts and new users alike whether you are a beginner to running or marathon veteran.
While it may not be the softest or most energetic max-cushioned shoe on the market, its balanced ride, durability, and comfort make it a standout option for a variety of runners.
For those looking for a tad more stability, the Glycerin GTS may be the way forward. Or if you want a bouncier ride, the Ghost Max may be more suited. But overall, the Glycerin 21 is another iteration that stands out from the rest and will please even the most critical of running fanatics.
