These Men's Brooks Glycerin GTS 21 road running shoes are great for hitting the pavement. To use them, simply slip your feet in and tie the laces to get a comfortable fit. When running, the shoes will support your natural motion, thanks to the GuideRails® system. For best results, make sure your feet are clean and dry before putting on the shoes. Avoid wearing them in very muddy or dirty conditions as much as possible. To clean, use a soft brush and mild soap to gently scrub the upper and sole. Let them air dry, away from direct heat sources. Don't machine - wash or tumble - dry these shoes, as it could damage the materials and affect their performance. If you notice any signs of wear, especially on the sole, it might be time to consider getting a new pair to keep your running experience safe and comfortable.
