Using these HEY DUDE Tahoe Classic shoes is a breeze. Just slip them on using the easy-on heel pull tabs and adjust the elastic laces with the lace keeper for a snug fit. They're great for all your outdoor activities. When it comes to maintenance, if they get dirty, you can gently wipe the synthetic upper with a damp cloth. Keep them away from harsh chemicals. And if you want to replace the insole for extra comfort, simply remove the removable foam insole and put in a new one. Also, don't expose them to extreme heat or cold for long periods to maintain their shape and performance.
