The Brooks Glycerin 21 is a highly regarded, comfortable daily trainer best suited for easy-paced runs, recovery, and walking. While it provides a plush, stable, and smooth ride, it is not designed for speedwork and may feel warm in hot conditions due to its knit upper. Potential buyers should be aware that the shoe has a snug, sometimes short-feeling fit due to extensive heel padding and may require a short break-in period to reach optimal flexibility.
