To use these Keen Utility men's work shoes, simply put them on like you would any other pair of shoes. They're great for work environments where you need foot protection. When it comes to cleaning, use a damp cloth to wipe off dirt from the water - resistant leather. For the mesh liner, you can gently scrub it with mild soap and water. Don't machine - wash these shoes as it might damage the steel toes and the construction. Make sure to dry them in a well - ventilated area, away from direct heat. Also, regularly check the steel toes for any signs of damage, and if you notice anything wrong, stop using the shoes and contact the manufacturer.
