Performance Comparison

When examining the responsiveness of both Glycerin models, it's crucial to consider the advancements in midsole technology.

The Glycerin 20's nitrogen-infused DNA Loft v3 not only enhances the shoe's responsiveness but also contributes to a lighter and bouncier feel.

In contrast, while the Glycerin 19 offers commendable performance, it doesn't match the refined responsiveness found in its successor.


In comparing the responsiveness of Brooks Glycerin 19 vs 20, it's clear that the latter's nitrogen-infused DNA Loft v3 midsole delivers a more lively and energetic ride. When evaluating these running shoes, I'm particularly discerning about the performance aspects that affect my runs.

  1. 1. Midsole Technology: The DNA LOFT v3 technology in the Brooks Glycerin 20 offers a significant advancement in cushion and responsiveness compared to the older model.
  2. 2. Energy Return: The Glycerin 20 feels more responsive underfoot, providing that extra spring with each stride.
  3. 3. Comfort and Performance: Despite its plush comfort, the responsiveness doesn't compromise the smooth transition from heel to toe.
  4. 4. Efficiency: The updated design of the Glycerin 20 translates to a more efficient run, allowing me to maintain my pace with less effort.

Delving into the design aspects of the Brooks Glycerin 20 vs 19, it's clear that both iterations showcase Brooks' commitment to combining aesthetics with functionality, yet they exhibit distinctive features that appeal to different runner preferences.

The Glycerin 19's upper construction prioritizes a plush interior, creating a snug and comfortable fit, while the 20 introduces a more streamlined, lightweight design that doesn't compromise comfort. Both models maintain an engineered mesh upper, but the Glycerin 20 refines this with a sleeker profile.

In terms of the heel, the Glycerin 19 offers a cozy, secure feeling, whereas the Glycerin 20 enhances the heel counter for better support without adding bulk. Each model balances the need for a comfortable ride with the structural integrity runners expect from a premium shoe.

The design evolution of the Glycerin series is a testament to Brooks' innovation. To get a broader perspective on how the Glycerin's design compares with other Brooks favorites, take a look at our comprehensive comparison of Brooks Ghost vs Glycerin.


Assessing the Brooks Glycerin models, it's evident that both models are engineered with materials and technologies designed to enhance their longevity and withstand the rigors of regular use. When I compare the two, here's what I find in terms of durability:

  1. 1. Outsole Robustness: Both shoes have high-abrasion rubber outsoles, yet the Brooks Glycerin 20 introduces subtle tweaks for improved wear resistance.
  2. 2. Midsole Durability: The recent DNA LOFT cushioning in the Glycerin 20 is designed to maintain responsiveness and comfort longer than the previous model.
  3. 3. Upper Wear: The engineered mesh in both running shoes is durable, but the Glycerin 20's upper might offer a slight difference in longevity due to updated materials.

Support and Stability

While evaluating the robustness and longevity, I've also scrutinized their performance in providing runners with the necessary support and stability. Both models offer commendable arch support, which is vital for a runner's foot health.

The foam technologies employed in these shoes, DNA LOFT for the 19 and the advanced nitrogen-infused version for the 20, contribute significantly to their stability. This is particularly important when considering the interaction between the runner's foot and the ground.

The Glycerin 20, with its updated foam, offers a more stable platform and improved energy return. Meanwhile, the collar design in both shoes ensures the foot is securely locked in place, reducing the likelihood of in-shoe slipping and enhancing overall stability.


When comparing comfort, breathability and cushioning are pivotal points of focus.

I've found that while the Glycerin 19 offers a well-cushioned ride, the 20 introduces an advanced DNA LOFT v3 cushioning that provides a softer and more responsive feel.

Moreover, the Glycerin 20's engineered air mesh upper significantly enhances breathability, potentially offering a more comfortable experience in warmer conditions.


Regarding breathability, the Brooks Glycerin 20 outshines its predecessor, offering a cooler and more ventilated running experience that doesn't compromise on comfort, even during the warmer months. Here's how:

  1. 1. Enhanced Upper Material: The Glycerin 20's engineered mesh is lighter and employs a more open weave pattern, allowing for greater airflow to keep feet cool.
  2. 2. Strategic Ventilation Zones: This running shoe features targeted ventilation areas that improve air circulation around high-sweat regions.
  3. 3. Moisture Management: The materials used in the Glycerin 20 are designed to wick away moisture more effectively, helping you stay dry and comfortably on the road.
  4. 4. Soft Interior Lining: Despite the focus on breathability, the shoe maintains a soft and plush interior, ensuring that comfort isn't sacrificed for the sake of staying cool.


The cushioning of Brooks Glycerin 20's nitrogen-infused DNA Loft v3 midsole offers a noticeably softer and more responsive ride compared to the traditional DNA Loft cushioning found in the Glycerin 19.

As a runner, I look for a shoe that can provide both comfort and performance, and the Glycerin 20 seems to hit the mark. The introduction of nitrogen has fine-tuned the softness without compromising on the bounce-back you'd expect from a high-caliber running shoe.

Moreover, the Glycerin 20 incorporates strategically placed flex grooves that work harmoniously with the updated midsole to enhance the overall feel underfoot. This results in a fluid transition from heel to toe, making my runs smoother and more enjoyable.

Final Verdict

Choosing between the Brooks Glycerin 19 and 20 depends on individual preferences. The Glycerin 19 offers reliable cushioning and a snug fit, ideal for those who appreciate consistency and a proven design. The Glycerin 20, with its advanced DNA Loft v3 technology, provides enhanced responsiveness, lighter weight, and better breathability, suitable for runners seeking innovation and comfort in warmer conditions.
