Using these HEY DUDE Tahoe Classic shoes is a breeze. Just slip them on through the easy - on system, adjust the elastic laces with the lace keeper to your comfort, and you're ready to hit the outdoors. When it comes to maintenance, you can use a soft brush to clean the synthetic upper gently. Avoid using harsh chemicals as they might damage the water - repellant treatment. If the insole gets dirty, simply remove it and wash it with mild soap and water, then let it air dry. Make sure to store your shoes in a cool, dry place when not in use to keep them in good condition. Also, be careful on extremely rough surfaces as it may wear out the rubber grip outsole faster.
