To use these Finn Comfort shoes, simply adjust the hook - and - loop straps to get a snug fit. Slip your feet in and you're ready to go! For cleaning, use a soft brush to gently remove dirt from the nubuck leather upper. Avoid using harsh chemicals as they may damage the leather. When it comes to the removable footbed, you can take it out and air it regularly to keep it fresh. Store the shoes in a cool, dry place away from direct sunlight to maintain their color and shape.
