Womens Glycerin 21 Neutral Running Shoe - Ultra Plush Cushioning

Our review of the Womens Glycerin 21 finds it best for runners and active walkers who prioritize long-lasting, cloud-like cushioning. The single biggest reason to consider this shoe is the upgraded nitrogen-infused DNA Loft v3 midsole that delivers a noticeably softer, yet responsive ride compared with prior models. The shoe pairs a plush internal stretch bootie and a broad platform to create smooth, stable transitions, making it a comfortable choice for road running, gym sessions, and long days on foot.

Key Features

• Supreme Softness: The nitrogen-infused DNA Loft v3 cushioning provides a plush, lightweight foam that absorbs impact for a softer feel on runs and walks.
• Neutral Support: Designed as a neutral shoe, it offers maximum cushioning without added stability posts, ideal for runners who do not need motion control.
• Plush Improved Fit: An internal stretch bootie and newly engineered warp knit upper wrap the foot comfortably and adapt to movement for fewer pressure points.
• Smooth Transitions: A broad midsole platform stabilizes the foot and promotes even heel-to-toe roll for less abrupt strides.
• APMA Acceptance: This model has earned the APMA Seal of Acceptance, indicating design benefits for foot health during regular use.

Who It's For

The Glycerin 21 is suited for recreational and dedicated runners who want maximum plush cushioning without added support features, and for walkers who spend many hours on their feet and value comfort and durability. Its neutral platform makes it a good match for those with neutral pronation or who already use orthotics and prefer a soft baseline ride.

Runners seeking firm responsiveness, racing speed, or heavy overpronation correction should look elsewhere; Brooks offers versions with added support or lighter racing models for those specific needs.
