[Looking for the latest version? Check out the men's Brooks Glycerin 19 and men's Brooks Glycerin 19 GTS.] The men's Brooks Glycerin 18 is back and softer than ever. Brooks updated its classic Glycerin line by adding more foam than ever before. Designers reconfigured the midsole to allow more DNA Loft foam—the softest foam Brooks makes—to fit between you and the pavement. A full-length rubber outsole increases the Glycerin 18’s softness and improves its durability, while added stretch in the upper creates a snug, comfortable fit. In the Brooks Glycerin 18 review, Fleet Feet testers said the plush step-in feel creates a great first impression, and it rides smoothly and evenly for many miles. Runners who crave a soft ride and easy fit will find both in the men's Brooks Glycerin 18.
