Brooks Glycerin GTS 21 (Men's)

The Glycerin GTS 21 is the stability version of the Glycerin 21, designed specifically for runners who need extra support and structure. Both models offer superior cushioning and comfort, characteristic of the Brooks Glycerin series. While the Glycerin 21 focuses on providing a plush, neutral running experience, the Glycerin GTS 21 includes GuideRails support technology to help manage excessive movement and keep your stride stable. This makes the GTS 21 an excellent choice for those with pronation issues, while the standard Glycerin 21 is ideal for those who prefer a softer and more flexible ride. Both models share similar designs and materials, ensuring high performance and a comfortable run regardless of your stability needs.
