These KEEN men's Newport H2 sandals are super versatile. For use, just slip your feet in and adjust the straps for a snug fit. You can wear them for hiking on trails or wading through streams. When it comes to care, after using them in water, let them dry in a well - ventilated area. Avoid direct sunlight as it might damage the materials. If they get dirty, use a mild soap and water to clean them gently. And always check the straps regularly to make sure they're in good condition.
