The Brooks Glycerin series has long been a favorite among runners seeking plush cushioning and smooth rides. With each new iteration, Brooks aims to refine and enhance their flagship neutral running shoe. The transition from the Glycerin 19 to the Glycerin 20 brought several notable updates, sparking curiosity among runners about which version is better suited for their needs. In this article, we’ll break down the key differences, improvements, and what remains great between these two popular models.
Design and Fit: A Subtle but Significant Update
Glycerin 19
The Glycerin 19 featured a soft, breathable mesh upper designed for comfort and flexibility. The fit was generally true to size, offering a roomy toe box and secure midfoot lockdown. The heel collar padding provided good comfort, but some users noted slight heel slippage during longer runs.
Glycerin 20
Brooks refined the upper in the Glycerin 20 with a more seamless and adaptive design, enhancing breathability and reducing irritation points. The updated fit includes a better heel lockdown with improved padding to reduce slippage. Additionally, the Glycerin 20 introduced the StealthFit version, which offers a snugger, sock-like fit for those who prefer less bulk and a more streamlined feel.
Winner: Glycerin 20 for improved comfort and a better heel fit.
Midsole Technology: Smoother and Softer Ride
Glycerin 19
Equipped with the DNA LOFT midsole, the Glycerin 19 delivered plush cushioning and responsive energy return. While the ride was smooth and cushioned, some runners found it slightly firm underfoot compared to previous versions.
Glycerin 20
The biggest leap came with the introduction of DNA LOFT v3, an upgraded midsole foam that’s lighter and softer, yet still durable. This provides an even more luxurious and responsive ride, reducing impact stress during runs without sacrificing stability.
Winner: Glycerin 20 with noticeably improved cushioning and energy return.
Outsole and Traction: Enhanced Durability and Grip
Glycerin 19
The outsole of the Glycerin 19 used strategically placed high-abrasion rubber, offering good durability and traction on a variety of surfaces. The segmented crash pad allowed for smooth heel-to-toe transitions.
Glycerin 20
Brooks refined the outsole pattern and used slightly more durable rubber compounds in the Glycerin 20. The updated crash pad design further improves flexibility and ground contact, enhancing smooth transitions and grip, especially on wet surfaces.
Winner: Glycerin 20 for better durability and traction improvements.
Weight Comparison: Lighter Without Sacrificing Comfort
- Glycerin 19: Approx. 10.4 ounces (women’s size 8)
- Glycerin 20: Approx. 9.8 ounces (women’s size 8)
The Glycerin 20 manages to reduce weight slightly, making it feel less bulky and more agile during runs, all while maintaining excellent cushioning.
Winner: Glycerin 20 for a lighter build.
Price and Availability
Since the Glycerin 20 is the latest model, it typically carries a higher retail price than the Glycerin 19, which may be available at discounted rates or outlet stores. For budget-conscious runners, the Glycerin 19 still offers great value with many of the same core features.
Final Verdict: Which Should You Choose?
| Feature | Brooks Glycerin 19 | Brooks Glycerin 20 | Best For |
|---|---|---|---|
| Fit and Comfort | Soft, roomy, occasional heel slip | Enhanced upper and heel lockdown | Runners seeking improved fit |
| Cushioning | Plush DNA LOFT foam | Softer, lighter DNA LOFT v3 | Those wanting a softer ride |
| Outsole Durability | Good grip and durability | Improved rubber and grip | Wet surface and longer runs |
| Weight | Slightly heavier (10.4 oz) | Lighter (9.8 oz) | Lightweight preference |
| Price | More affordable | Premium pricing | Budget vs latest tech |
If you want the absolute latest in cushioning technology, fit improvements, and outsole durability, the Brooks Glycerin 20 is the clear winner. However, if you’re looking for a reliable, plush, and more budget-friendly running shoe, the Glycerin 19 still holds its ground as an excellent choice.
Conclusion
The Brooks Glycerin 20 builds on the strengths of the Glycerin 19 with thoughtful enhancements that elevate comfort, cushioning, and performance. Whether you choose the 19 or the 20, you’re investing in a high-quality running shoe designed for neutral runners who crave softness and smooth transitions. Your decision ultimately comes down to how much you value the latest updates versus your budget and personal fit preferences.
