Overview
This is Brooks vs Brooks — two of the brand's most popular shoes serving different needs. The Glycerin 20 is Brooks' max-cushion neutral trainer. The Adrenaline GTS 23 is their flagship stability shoe. Both use Brooks' DNA LOFT foam technology but with key differences.
Cushioning
The Glycerin 20 wins hands down on cushioning. Its DNA LOFT v3 foam is the softest in Brooks' lineup, with a 36mm stack height that absorbs every impact. The Adrenaline GTS 23 has plenty of cushion too, but it's firmer and more responsive — prioritizing support over pure plushness.
Stability Features
The Adrenaline GTS 23 features GuideRails — holistic support rails that keep your feet in their natural motion path. This prevents excessive inward or outward rolling. The Glycerin 20 has no stability features and relies on your natural gait. Overpronators should choose the Adrenaline.
Weight & Price
The shoes weigh nearly the same, but the Glycerin costs $20 more ($159.95 vs $139.95). The premium pays for the upgraded DNA LOFT v3 foam and plushier ride.
Who Should Buy Each
Choose the Glycerin 20 if: You're a neutral runner who wants maximum cushion for long runs and recovery days. You don't need stability features.
Choose the Adrenaline GTS 23 if: You overpronate and need guidance without sacrificing comfort. Great all-around training shoe at a lower price.
wb_sunny Why This Matters for Florida Runners
On Florida's flat, hard surfaces, the Glycerin 20's extra cushion is a real benefit — it protects your joints from the relentless concrete and asphalt. The Adrenaline is the better choice if you notice your ankles rolling inward, especially during long Florida summer runs when fatigue sets in and form breaks down. Both are available at most Florida running stores for in-person fitting.
