Brooks Glycerin vs Adrenaline GTS: Cushion vs Stability
emoji_events Quick Verdict
Choose the Glycerin 23 for the softest ride Brooks makes — it is the long-run and recovery-day shoe. Choose the Adrenaline GTS 25 if you overpronate and want GuideRails support. They now weigh the same, so the decision is purely neutral-versus-stability, and the Glycerin costs $20 more.

Is the Brooks Glycerin or Adrenaline better?
Neither is better for everyone. The Brooks Glycerin 23 is the softer, max-cushion neutral shoe for easy days and long runs. The Adrenaline GTS 25 adds GuideRails support for runners who overpronate or want a steadier daily trainer. They weigh the same, so choose by stability need, then by the $20 price gap.
Overview
This is Brooks vs Brooks — the two shoes most Florida runners end up deciding between. The Glycerin 23 is the brand's max-cushion neutral trainer. The Adrenaline GTS 25 is its flagship stability shoe. They sit in different categories, but the latest updates pulled them closer together than they have ever been.
What changed in the latest versions
Both shoes got a lower heel-to-toe drop. The Glycerin went from 10mm to 8mm and switched to Brooks' DNA Tuned midsole, which adds foam under the forefoot. The Adrenaline came down from 12mm to 10mm and picked up more DNA Loft v3. If you are coming off an older pair of either shoe, the ride will feel flatter and more modern under the forefoot — that is the single biggest difference you will notice out of the box.
Cushioning
The Glycerin 23 still wins on pure softness. It stacks 38mm in the heel and 30mm in the forefoot, and DNA Tuned is the plushest foam in the Brooks lineup. The Adrenaline GTS 25 is close on paper at 37mm and 27mm, but it rides firmer and more controlled — it is tuned for support, not for sinking in.
Stability features
The Adrenaline GTS 25 has GuideRails, Brooks' support system that limits excess inward and outward roll without the rigid medial post older stability shoes used. The Glycerin 23 has no stability structure at all and leaves your gait alone. If your ankles collapse inward, that difference matters more than anything else on this page. Brooks also sells a Glycerin GTS if you want the plush ride with GuideRails added.
Weight and price
The two shoes now weigh exactly the same — 10.6 oz in a men's 9, 9.5 oz in a women's 8. Neither is light. The Glycerin lists at $175 and the Adrenaline at $155, so the $20 premium buys the softer foam and nothing else.
Who should buy each
Choose the Glycerin 23 if: you are a neutral runner who wants maximum cushion for long runs and recovery days, and you want the softest thing Brooks makes.
Choose the Adrenaline GTS 25 if: you overpronate, or you want a do-everything daily trainer with a little guidance built in. It is also the cheaper of the two.
wb_sunny Why This Matters for Florida Runners
On Florida's flat, hard surfaces, the Glycerin 23's extra cushion is a real benefit — it protects your joints from relentless concrete and asphalt with almost no elevation change to break up the impact. The Adrenaline GTS 25 is the better choice if you notice your ankles rolling inward, especially on long Florida summer runs when fatigue sets in and form breaks down. Both are stocked at most Florida specialty running stores, so you can get fitted in person before you buy.

What are Brooks Adrenaline GTS good for? expand_more
The Brooks Adrenaline GTS is good for runners with mild to moderate overpronation. It's ideal for daily training, long runs, and walking. The GuideRails system provides gentle stability without feeling rigid or heavy.
Is the Brooks Glycerin good for plantar fasciitis? expand_more
The Brooks Glycerin can help with plantar fasciitis due to its excellent cushioning, but it's not a stability shoe. If your PF is related to overpronation, the Adrenaline GTS or Glycerin GTS (stability version) is a better choice.
Is the Brooks Adrenaline GTS more stable than the Glycerin? expand_more
Yes. The Adrenaline GTS 25 has GuideRails, which limit excess inward and outward roll; the Glycerin 23 is a neutral shoe with no stability structure. If you want Glycerin cushioning with support, Brooks sells the Glycerin GTS 23.
Which is better for long runs, the Glycerin or the Adrenaline? expand_more
The Glycerin 23. Its DNA Tuned midsole and 38 mm heel stack make it the softer shoe over distance, which matters on Florida's flat concrete. Pick the Adrenaline GTS 25 for long runs only if your ankles roll inward late in a run and you want GuideRails holding your form.
