Welcome to Flawless Shoe Reviews. Today we’re comparing two of the most popular stability running shoes on the market: the Brooks Adrenaline GTS 24 and the Brooks Glycerin GTS 22.
While both shoes use Brooks’ signature Go-To Support system, they provide stability in different ways and feel distinctly different underfoot. Whether you’re looking for a comfortable lifestyle shoe, standing all day, or support on long runs, we’ll help you choose the right one for your needs.
Midsole and Cushioning: DNA Loft vs DNA Loft v3
Let’s start with how each shoe feels underfoot.
Brooks Adrenaline GTS 24
- Midsole: DNA Loft v2 (nitrogen-injected foam)
- Offers a more balanced feel from heel to toe
- Softer overall than the Glycerin GTS
The Adrenaline provides consistent comfort across the foot with a stable, smooth ride. It’s a great option if you want a moderate stability shoe that doesn’t feel overly firm under the heel.
Brooks Glycerin GTS 22
- Midsole: DNA Loft v3 (tuned nitrogen-infused foam)
- Larger midsole cells in the heel for vibration absorption
- Narrower cells in the forefoot for a snappier toe-off
This midsole setup feels firmer at heel strike than the Adrenaline and firmer than the previous GTS 21 model. It makes the Glycerin GTS 22 feel more like a max stability shoe.
Stability Features and Sole Geometry
Both models use Brooks’ Go-To Support (GTS) system, which includes a denser foam pattern under the arch for added control. But how that stability feels underfoot is different.
- Adrenaline GTS 24: The support feels subtle and balanced, ideal if you want light-to-moderate stability.
- Glycerin GTS 22: The firmer heel and more prominent arch support make it feel like a max stability shoe, especially for those who need more guidance on impact.
Sole Flare Comparison
- The Glycerin GTS 22 has a wider forefoot base with more lateral sole flare—great for those who supinate or want more ground contact.
- The Adrenaline has less flare, making it feel more streamlined and agile.

Fit, Upper, and Comfort
Toe Box & Width
- Glycerin GTS 22 offers a slightly roomier toe box than the Adrenaline
- Both models are available in normal, wide, and extra-wide widths
Tongue & Heel
- Both shoes use non-gusseted padded tongues
- The Glycerin includes a pull tab at the heel, which is missing on the Adrenaline
- Both shoes feature generous heel cushioning, though the Glycerin is slightly more plush
If you value a bit more room and step-in comfort, the Glycerin may be preferable. If you prefer a lighter, more structured feel, the Adrenaline fits the bill.
Drop, Stack Height, and Daily Use
| Feature | Adrenaline GTS 24 | Glycerin GTS 22 |
|---|---|---|
| Heel Stack | 35 mm | 39 mm |
| Forefoot Stack | 23 mm | 29 mm |
| Drop | 12 mm | 10 mm |
| Weight (US Men’s 9) | 283 g | 303 g |
Both shoes feature a high drop, which can benefit those with Achilles tightness or discomfort. However, the elevated heel can increase pressure on the ball of the foot, so if you’re standing all day and get forefoot discomfort, you may prefer lower-drop shoes like the Hoka Gaviota 5.
Performance and Running Use
- Glycerin GTS 22: Heavier and more cushioned—better for recovery runs, long runs, or daily comfort. Not ideal for speed workouts.
- Adrenaline GTS 24: Slightly lighter with more responsiveness—better suited to everyday training and light tempo runs, but still not built for fast strides.
For a max-cushion shoe with better speed capability, you might consider the Brooks Ghost Max 2.

Final Thoughts: Which One Should You Buy?
- Choose the Adrenaline GTS 24 if you want a moderate stability shoe that’s softer, slightly lighter, and versatile enough for both walking and running.
- Choose the Glycerin GTS 22 if you need maximum stability, firmer heel support, and a roomier fit for long days on your feet or recovery-focused runs.
Both shoes are top-tier stability options—but they cater to different preferences.
