Using these Propét DuroCloud® 392 Men's Sneakers is a breeze. Just slip them on like you would with any regular shoes and you're ready to go for your workout or daily activities. When it comes to maintenance, it's simple. For light dirt, you can use a soft brush or a damp cloth to gently clean the mesh upper. Avoid using harsh chemicals as they may damage the material. If the insoles get dirty, you can remove them and hand - wash them with mild soap and water, then let them air dry. Also, make sure to store your sneakers in a cool, dry place. Don't leave them in direct sunlight for too long as it may cause the color to fade. When using the insole system, remember that you can adjust the fit according to your needs. If you feel like you need more space inside the shoe, you can take out the bottom insole. And if you have custom orthotics, just remove both insoles and insert your own.
