Brooks’ softest cushioning meets its reliable stability in the women's Glycerin 19 GTS. Designers gave the Glycerin a bed of DNA Loft foam to cushion your steps. The foam is the softest one in Brooks’ lineup, which guarantees the plush feeling you crave for your everyday miles. An engineered mesh upper provides breathable support and maintains a light weight, while a blown rubber outsole increases the Glycerin’s durability and traction on pavement. The defining feature of the Glycerin 19 GTS, though, is Brooks’ GuideRails technology. The subtle stability feature helps keep your body in its natural motion path and reduces excess movement to keep you running smoothly. In the Brooks Glycerin 19 GTS review, Fleet Feet runners said the DNA Loft foam delivers a soft, engaging ride, while the GuideRails are there when you need them but disappear when you don’t. For the softest, most stable ride, look no further than the women's Brooks Glycerin 19 GTS. Love the cushion but don’t need GuideRails? See the neutral women's Brooks Glycerin 19.
