Trying to decide between the Glycerin GTS and the Glycerin GTS 21? You’re definitely not the only one scratching your head over these two popular Brooks running shoes. Whether you’re just starting out or training for your next marathon, picking the right pair can really make a difference in how you feel on your runs. Let’s dive into the details and see which shoe comes out on top.
1. Design & Style: Which One Catches Your Eye?
Both the GTS and GTS have their own unique look. The GTS sticks to a classic, bold design with some eye-catching color options. On the other hand, the GTS feels a bit more modern and sleek, with smoother lines and fresh colors that are right on trend for 2025. If you want something that looks as good on the street as it does on the track, the newer model might be more your style.
2. Cushioning & Comfort: Is It Like Running on Clouds?
Cushioning is where these shoes really show their stuff. The GTS uses Brooks’ DNA Loft foam, which gives you that soft, plush feel underfoot. The GTS steps it up with DNA Loft v2, which is lighter and bouncier but still super comfy. So, if you’re all about that perfect mix of softness and energy return, the GTS might just feel like a dream on your feet.
3. Support & Stability: Keeping Your Stride Steady
If you tend to overpronate or just want some extra stability, both shoes have you covered. The GTS features Brooks’ GuideRails system to keep your feet aligned and reduce unnecessary movement. The GTS improves on this with enhanced GuideRails that offer even better medial support. This means less risk of injury and a more natural stride, whether you’re pounding the pavement or hitting the trails.
4. Weight & Durability: Light Enough to Fly, Tough Enough to Last
The GTS is a bit on the heavier side because of its denser midsole materials. The GTS trims down the weight, making it feel lighter and quicker—perfect for speed workouts or faster runs. Both shoes are built to last between and miles, but the GTS features an improved outsole tread pattern that grips better and holds up longer. So, if you want something that’s both light and durable, the GTS might be your best bet.
5. Price: What Will It Cost You?
Since the GTS is an older model, you can usually find it for less—around $ to $140. The GTS 21, with all its new tech, comes in a bit higher, typically between $ and $170. If you’re watching your budget, the GTS offers solid value. But if you want the latest features and a fresh look, investing in the GTS could be worth it.
6. What Are Runners Saying? Real User Feedback
Here’s a quick look at what people who’ve actually worn these shoes think:
- GTS 20: Loved for its comfort and support, praised for affordability, but some say it feels a bit heavy and less breathable.
- GTS 21: Applauded for being lightweight and stylish, with better cushioning, but a few users mention it runs narrow and costs more.
Hearing from real runners can give you a better sense of what to expect beyond the specs.
7. Who Should Pick Which Shoe?
Here’s a quick guide to help you decide based on your running style:
- Casual Joggers: GTS for comfort and budget-friendly price.
- Speed Trainers: GTS for a lighter, more responsive feel.
- Overpronators: GTS with its enhanced stability features.
- Long-Distance Runners: GTS for better cushioning on those marathon miles.
- Style Lovers: GTS for the fresh, trendy look.
8. Durability: Which One Lasts Longer?
Both shoes are made to go the distance, but the GTS has a few upgrades that might give it the edge:
- Improved outsole tread for better grip and longer wear.
- Midsole foam that resists flattening over time.
- More reinforced upper materials for added durability.
- Overall build feels a bit more refined and sturdy.
If you want a shoe that stays fresh and supportive for hundreds of miles, the GTS is a solid choice.
9. How Do They Stack Up Against Other Running Shoes?
When compared to other popular running shoes like the Nike Air Zoom Pegasus 40, ASICS Gel-Kayano 30, or New Balance Fresh Foam 1080v13, the GTS stands out for its cushioning and support. While some competitors might be faster or cheaper, Brooks’ latest model offers a great balance of comfort, stability, and style that many runners love.

To sum it up, here are the key differences:
- The GTS has upgraded cushioning and feels lighter on your feet.
- It offers better stability with enhanced GuideRails.
- The GTS is more budget-friendly and still very comfortable.
