These Dunham men's grey Captain boat shoes are super easy to use. Just slip them on and you're ready to go, whether you're walking on the dock or strolling in the park. For best results, make sure your feet are clean and dry before putting them on. When it comes to maintenance, use a soft brush to gently clean the dirt off the shoes regularly. Avoid soaking them in water for a long time as it may damage the materials. Store them in a cool, dry place when not in use. If the footbed gets dirty, you can remove it and wash it with mild soap and water, then let it air - dry completely before putting it back in the shoes.
