AI summary of 5 reviews · as of Jun 2026
The Glycerin 20 delivers improved bounce and responsiveness through its DNA Loft v3 foam, but remains heavy and pedestrian compared to lighter, more engaging daily trainers at similar or lower cost.
Where reviewers disagree: One reviewer suffered blisters from excess forefoot room while others found the roomier fit an improvement; Opinion split on whether the DNA Loft v3 delivers enough liveliness—some felt it matched the Aurora BL's pop, others found it subdued; Disagreement on value: one reviewer sees it as expensive for what it offers, another emphasizes durability justifies the outlay
Reviewers splitWhat they praise
- DNA Loft v3 foam is noticeably more responsive and lively than previous glycerin versions
- Exceptionally durable rubber outsole that withstands high mileage with minimal wear
- Comfortable step-in feel with generous padding around collar and tongue
- Fit runs roomier and wider than the previous version, with better toe-box space
- Stable platform suitable for easy runs and long distances
What they knock
- Heavy for a daily trainer at around eleven ounces for men, over eight for women
- Extensive rubber coverage deadens the foam and reduces the bouncy feel
- Foam feels medium-firm rather than truly soft despite cushioning claims
- Not nimble or snappy enough for tempo work or faster paces
- Design looks dated and unchanged from earlier iterations

Frequently asked
What buyers want to know.
What is Brooks Glycerin 20 good for?
The Glycerin 20 is built for easy runs, long distances, and all-day comfort. Reviewers say it excels when cushioning and stability matter more than speed or weight.
Who should buy the Glycerin 20?
Runners with wide feet benefit from the roomier fit and reduced impact pain. It suits anyone prioritizing maximum cushioning and durability over a lighter, more responsive ride.
What are the main drawbacks?
The shoe is heavy for a daily trainer. Reviewers note the extensive rubber coverage mutes the foam's bounce, and the shoe is not nimble enough for tempo work or faster paces. The design looks dated.
How comfortable is the Glycerin 20?
Reviewers praise the generous padding around the collar and tongue, and the roomier fit gives better toe-box space. One reviewer experienced blisters from the extra forefoot room, so fit varies by individual.
How durable is the Glycerin 20?
Reviewers highlight the exceptionally durable rubber outsole that withstands high mileage with minimal wear. Some reviewers see this durability as justifying the cost.
Does the new foam make a real difference?
Reviewers say the DNA Loft v3 foam is noticeably more responsive than earlier versions, but opinion splits on whether it delivers enough liveliness. The foam feels medium-firm rather than truly soft despite cushioning claims.
