The Brooks Glycerin GTS 21 is a daily trainer designed for runners seeking moderate stability. With a notable 12 mm drop, it is particularly beneficial for heel strikers who require additional cushioning. The verified support and comfort stem from the firm 31.5 HA foam, which provides a stable platform during runs.
While the outsole demonstrates durability, lasting through extensive wear, the upper may retain warmth, impacting breathability. Additionally, its performance at faster paces is limited, which may affect versatility in various conditions. Regardless of these factors, the Brooks Glycerin GTS 21 remains a favorable choice for those looking for support without opting for a full stability model.
