These OOFOS women's OOlala Luxe sandals are super easy to use. Just slip your feet in and you're ready to go, whether you're out for a walk during the day or heading to a casual evening event. When it comes to maintenance, since the closed - cell foam is machine - washable, you can simply toss them in the washing machine on a gentle cycle. Just make sure to let them air dry completely. As for usage, try not to wear them in extremely rough or abrasive environments as this might damage the foam. These sandals are great for everyday use, but like all shoes, they'll last longer with proper care.
