Super-soft cushioning for supreme comfort with extra support. Get carried away in the weightless softness of the Glycerin 21, featuring more nitrogen-infused DNA LOFT v3 cushioning than before. Brooks magnified the plushness to elevate softness to new levels.
Comfortable, accommodating fit:
New engineered warp-knit provides fantastic breathability in a fit that's flexible and accommodating. Plus the new materials feel super soft against your foot.
Smooth and stable transition:
The wider platform allows more surface area for your foot to land and transition from heel-to-toe smoothly and steadily.
Brooks focuses beyond the feet to the most injury-prone part of a runner's body: the knees. GuideRails® support keeps you moving comfortably.
