These Keen Utility men's safety shoes are easy to use. Just slip them on like regular shoes and you're ready to work. When wearing them, make sure the shoes fit well to avoid discomfort. As for maintenance, keep them clean by wiping with a damp cloth regularly. Avoid using harsh chemicals as they may damage the materials. Also, check the outsoles for wear and tear periodically. If the footbed gets dirty, you can remove it and wash it gently. And don't forget to let the shoes dry naturally in a well - ventilated area after cleaning.
