The Brooks Glycerin GTS 22 delivers an expertly balanced ride that combines luxurious comfort with responsive performance. This max-cushioned trainer features all-new, nitrogen-infused DNA Tuned cushioning, engineered with innovative dual-size cell technology which allows Brooks’ designers to create different zones of cushioning. The result gives you plush landings in the heel that transition smoothly into energetic toe-offs, making your miles feel effortless. Plus, Brooks’ GuideRails® technology supports your body in its natural motion path while keeping excess motion in check. Details: Upper: A new engineered double jacquard mesh upper provides a premium, adaptable fit with a plush heel collar and stretchy heel tab for easy on/off. The sock-like construction wraps your foot in comfort while keeping it secure. Midsole: DNA Tuned cushioning uses larger cells in the heel for soft landings and smaller cells in the forefoot for responsive toe-offs. Brooks’ GuideRail® holistic support system supports your body in its natural motion path while keeping excess movement in check, similar to bumpers on a bowling alley. Outsole: Durable rubber provides reliable traction and long-lasting wear.
