Brooks Women's Glycerin GTS 21

For the Glycerin GTS 21 women's running shoe, we added 2mm more super soft DNA LOFT v3 cushioning for extra plushness, while Brooks' innovative GuideRails support system keeps you comfortably in stride. Plus an updated, streamlined upper delivers breathability.

Supreme softness

Improved fit
New, engineered warp knit upper is breathable and allows for a flexible, accommodating fit while staying soft against your foot.

Smart support
Brooks' innovative Guide RailsⓇ technology supports your body in its natural motion path while keeping excess movement in check
