The Brooks Glycerin GTS 21 is a premium, well-cushioned daily trainer designed for runners who need mild stability. While many users love its comfort for long, easy miles, there is a notable split in feedback regarding the toe box design, with some users reporting significant discomfort from a new stiffening feature. It is a reliable, high-quality choice for those looking for support without a heavy, rigid feel, though it is not recommended for speed work.
