The GLYCERIN GTS 21 W from Brooks is an even lighter and softer women's road running shoe.

Thanks to a DNA Loftv3 midsole, transitions are smoother and cushioning is ultra-soft, offering lightness, responsiveness and durability with soft comfort.
It also features a GuideRails support system that allows the sportswoman's body to align itself with its natural movement, while controlling excessive movements. The shoe also features a durable RoadTack rubber outsole.

Finally, the breathable mesh sockliner provides a secure fit and comfortable support for the foot. The lacing system provides a precise, made-to-measure fit.
