In this comparison, we examine the Brooks Women’s Glycerin 21 Neutral Running Shoe and the Brooks Women’s Glycerin Stealthfit 22 Neutral Running Shoe. Both shoes are priced at $114.95 and cater to neutral runners seeking maximum cushioning. However, they feature different technologies and designs that may influence your purchasing decision.

Design and Aesthetics

The Brooks Women’s Glycerin 21 features a black, grey, and white color scheme, providing a classic yet modern look. In contrast, the Glycerin Stealthfit 22 showcases a white, grey, and black design that offers a sleeker, more contemporary appearance. The Glycerin 21 has a traditional upper design, while the Glycerin Stealthfit 22 boasts an updated flat knit upper that enhances fit and flexibility. This design difference could appeal to those who prioritize aesthetics alongside performance.

Cushioning Technology

When it comes to cushioning, the Glycerin 21 incorporates super-soft nitrogen-infused DNA Loft v3 cushioning, designed to be lightweight and responsive. On the other hand, the Glycerin Stealthfit 22 utilizes DNA Tuned technology, which integrates dual-size cells for a balanced feel between plush landings and energetic toe-offs. While both shoes offer excellent cushioning, runners may prefer the enhanced adaptability of the Stealthfit 22's design, particularly for varied running conditions.

Comfort and Fit

The Glycerin 21 is engineered with a plush internal fit, featuring a stretch bootie that surrounds the foot for added comfort. This shoe is praised for its smooth, stable transitions, making it suitable for various activities beyond running. In comparison, the Glycerin Stealthfit 22 also emphasizes comfort with its accommodating flat knit upper, which offers a blend of stretch and compression. This difference in fit could affect how each shoe feels during extended wear, with the Stealthfit 22 potentially providing a more adaptive experience.

Performance on the Road

Both shoes excel in providing neutral support, making them ideal for road running, cross training, and gym workouts. The Glycerin 21 has a sales rank of 29,881, while the Glycerin Stealthfit 22 ranks significantly higher at 14,424, suggesting that the latter might be favored by consumers for its performance. The broad platform in both shoes stabilizes the foot and promotes smooth heel-to-toe transitions, but the Stealthfit 22 may offer an edge due to its advanced cushioning technology.

Weight and Durability

While specific weight details are not provided, the Glycerin 21 is described as being lightweight and durable, thanks to its nitrogen-infused cushioning. The Glycerin Stealthfit 22 also emphasizes durability with its updated materials. However, the Glycerin 21 has the advantage of being an established model with proven longevity in performance. Runners looking for a time-tested option may lean towards the Glycerin 21, while those interested in the latest innovations may prefer the Stealthfit 22.

Suitable Activities

Both shoes are designed for a variety of activities, including road running and gym workouts, making them versatile choices. The Glycerin 21's plush cushioning is particularly suited for long-distance runs, while the Glycerin Stealthfit 22's DNA Tuned technology may appeal to runners who enjoy a balance of cushioning and responsiveness. Your choice may depend on whether you prioritize comfort for longer runs or a more dynamic feel for varied training sessions.

Pricing and Availability

Both models are priced identically at $114.95, making them equally accessible to consumers. However, the Glycerin 21 has an average price of $115.22 over the past 90 days, while the Glycerin Stealthfit 22 has an average of $115.85 in the same period.
