To use these Finn Comfort shoes, just slip your feet in and adjust the hook - and - loop straps to your desired tightness. When wearing them, make sure your feet are clean and dry to avoid any unpleasant odors. For maintenance, use a soft brush to remove dirt from the leather upper regularly. You can also apply a leather conditioner occasionally to keep the leather soft and supple. Avoid wearing these shoes in extremely wet or muddy conditions for long periods as it may damage the leather. When not in use, store them in a cool, dry place.
