These Olukai men's Ulele sandals are super easy to use. Just slip your feet in and you're ready to go. Whether you're walking on the beach, going for a hike, or just out for a casual day, these sandals will keep you comfortable. When it comes to cleaning, you can rinse them with water after getting them dirty, especially if they've been in saltwater. Let them air dry naturally. Avoid using harsh chemicals or putting them in the dryer as it might damage the water - resistant materials and the grip. Also, make sure to check the straps regularly to ensure they're tight enough for a secure fit but not too tight to cause discomfort. That way, your sandals will last you a long time and keep performing well.
