THE GENDER-SPECIFIC SHOE FOR RUNNERS

The Glycerin 21 is the ideal choice for men looking for super-soft cushioning and supreme comfort. Its plush internal fit and soft, stable transitions ensure a surrounding of super-softness. This Brooks Glycerin 21 has earned the APMA Seal of Acceptance.

NEUTRAL SUPPORT

The Glycerin 21 provides neutral support while offering maximum cushioning. It's perfect for road running, cross training, the gym, and wherever else you take your runs. Its predecessor is the Glycerin 20. For added support, consider the GTS 21 from Brooks.

SUPREME SOFTNESS

Experience the ultimate in softness with the Glycerin 21, featuring even more super-soft nitrogen-infused DNA Loft v3 cushioning. This cushioning is optimized to be lightweight, responsive, and durable, providing plush comfort for your runs.

PLUSH IMPROVED FIT

The Glycerin 21’s plush feel comes from an internal stretch bootie that surrounds your foot and moves and expands with your stride. The newly engineered warp knit upper is breathable and allows for a flexible, accommodating fit while staying soft against the foot.

SMOOTH, STABLE TRANSITIONS

The broad platform of the Glycerin 21 stabilizes your foot and promotes smooth heel-to-toe transitions, enhancing both comfort and performance during your runs.
