How to use: Just slip your feet into these shoes and start your running or athletic activities. They're great for daily runs, workouts at the gym, or any kind of physical exercise. Notice: Make sure your feet are clean and dry before putting on the shoes to keep the interior fresh. Avoid wearing them in extremely muddy or dirty environments as it can be hard to clean. Maintenance: Regularly wipe the shoes with a damp cloth to remove dirt. Let them air - dry naturally, don't use a dryer as it may damage the materials. If the insole gets smelly, you can take it out and wash it gently with mild soap and water, then let it dry completely before putting it back in.
