Indulge in supreme softness with the Brooks Glycerin 21, featuring nitrogen-infused DNA LOFT v3 cushioning for the ultimate plush experience.

With a substantial stack height of 36mm heel/26mm forefoot, it provides luxurious comfort mile after mile. The engineered warp knit upper moves with your foot while providing secure support. Designed for runners who want maximum cushioning without sacrificing responsiveness, perfect for long runs, recovery days, and high-mileage training.
Sizing
Length: True to size
Width and toebox: A more spacious forefoot than the Glycerin 21, which had a restrictive taper. Standard, wide and extra-wide offered.
Fit notes: Excellent lockdown with no heel slippage or foot translation, a normal-width midfoot with good hold, and a stiff, structural heel counter that could be aggressive for sensitive heels. A plush upper and padded tongue mean essentially no break-in.
