The Glycerin 21, a descendant of a lineage spanning over two decades, hails from Brooks' commitment to superior cushioning. Released in January 2024, the 'Summer Melts Pack' variant, specifically in 'Vanilla,' embodies a limited-edition design. This iteration continues the legacy of the Glycerin series, a cornerstone in Brooks' 'cushion' branch.
Primarily designed as a max-cushioned daily trainer, the Glycerin 21 excels in slow, easy, and recovery runs, as well as high-volume mileage and long runs. Its design also makes it a comfortable walking shoe. The shoe's construction supports neutral runners with medium to high arches, offering a roomy toe box and a streamlined fit.
The Brooks Glycerin series, as a whole, has long held a prominent position within the running community, favored for its supreme cushioning and adaptive design. The Glycerin 21, as the latest evolution, is poised to maintain this stature. The brand's commitment to innovation and runner-focused design has solidified its influence within the running subculture, particularly among those valuing comfort and performance.
The upper is meticulously crafted from an engineered warp knit, offering lightweight breathability, complemented by a luxuriously padded interior. The midsole features nitrogen-infused DNA LOFT v3 foam, providing exceptional softness and responsiveness. RoadTack rubber forms the outsole, ensuring high traction and durability, while the design incorporates waffle cone accents and a confetti-freckled path on the logo.
