These men's loafers are super easy to use. Just slip them on and off. When choosing a size, make sure to measure your feet carefully and match with our size guide. For maintenance, keep them away from sharp objects to avoid scratching the leather. You can use a soft leather cleaner to wipe them clean. After cleaning, let them dry naturally in a well - ventilated area. In wet weather, the waterproof feature will protect your feet, but don't soak them in water for a long time. Enjoy wearing these stylish and functional loafers all season long!
