Using these Wolky Tahiti sandals is a breeze. Just slip your feet in and adjust the velcro instep strap to your comfort level. They're great for all your summer activities, whether you're taking a stroll on the beach or running errands. As for maintenance, keep them clean by gently wiping with a damp cloth. Avoid getting them soaked in water for long periods as it may damage the leather and the velcro. When not in use, store them in a cool, dry place. If you notice the memory foam footbed losing its shape over time, you can give it a break by not wearing the sandals for a few days. And always check the size before purchasing to ensure the best fit for your standard - sized feet.
