These OOFOS sandals are super easy to use. Just slip them on your feet whenever you need some relief, like after a long run or a tiring day at work. As for care, you can simply toss them in the washing machine, which is great for keeping them clean. Remember, although the closed - cell foam is designed to resist odor, it's still a good idea to let them air - dry fully after washing. Also, don't expose them to extreme heat or sharp objects that could damage the foam. With proper use and care, these sandals will keep providing you with excellent support for a long time.
