Pros
- Extremely durable with high-quality construction
- Excellent for long, easy-paced mileage and recovery runs
- Stable platform for heel-strikers
- Comfortable upper with a plush, slipper-like feel
Cons
- Laces tend to come undone easily (Glycerin 20)
- Firm ride despite marketing claims of supreme softness
- Heavy due to extensive rubber on the outsole
- Not recommended for speed work or interval training
- Inconsistent fit reports from long-time users
⚠ Red flags
- Marketing claims regarding softness may not match on-road feel for all users
- Fit consistency can vary between iterations (e.g., toebox size)
Better options
Why switch: The successor to the Glycerin 20, featuring more cushioning (an additional 2mm of DNA LOFT v3 foam) and a more modern upper design while maintaining the same core feel.
Recommended by reviewers for runners seeking a more energetic ride and better responsiveness compared to the Glycerin series.
