Using these shoes is easy. Just lace them up and start your run. When you're running, the wide fit and great support will keep your feet stable. As for maintenance, you can clean them with a soft brush and mild soap when they get dirty. Don't use harsh chemicals as they might damage the mesh or the foam. After cleaning, let them air - dry. It's also a good idea to store them in a cool, dry place. Remember, these shoes are designed for running, so try not to use them for other rough activities to keep them in good condition.
