These Keen Outdoor sandals are super versatile. You can wear them for water sports like kayaking or for hiking on the trails. To put them on, simply use the quick - cinch bungee lacing. Pull it tight for a snug fit and loosen it when you want to take them off. When using them in water, they'll dry quickly thanks to the quick - dry lining. For maintenance, you can wash the polyester webbing upper with mild soap and water. Let them air dry completely. Avoid using harsh chemicals as they might damage the material. Also, make sure to store them in a cool, dry place when not in use. These sandals are designed to last, but taking good care of them will keep them in top shape for all your adventures.
