Using these men's loafers is super easy. Just slip them on and you're ready to go! When choosing a size, make sure to measure your feet from heel to toe and compare with the size guide provided. That way, you'll get a perfect fit. For maintenance, keep them away from sharp objects to avoid scratching the microfiber upper. If they get dirty, you can gently wipe them with a damp cloth. Since they're waterproof, a little rain won't hurt them, but try not to soak them for a long time. After use, let them dry in a well - ventilated area. These shoes are designed for spring and autumn, so store them properly during other seasons to keep them in good condition.
