The Brooks Glycerin 23 refines one of the most trusted cushioned trainers in running, delivering an even smoother, softer, and more balanced ride for everyday miles and long runs alike. Building on the major redesign of the Glycerin 22, this latest iteration introduces DNA Tuned cushioning and a slightly lower drop to enhance comfort, flow, and toe-off efficiency. Dual-cell midsole technology absorbs impact through the heel while remaining responsive under the forefoot, creating seamless transitions throughout the gait cycle. Combined with a redesigned engineered knit upper and Brooks’ renowned durability, the Glycerin 23 offers plush comfort and dependable performance mile after mile.
