Using these Drew Serenity sandals is easy. Just adjust the three hook - and - loop straps to fit your feet comfortably. You can leave the Walk Right footbed in for extra cushioning or take it out if you need to use a custom orthotic. For casual outings or dressy events, these sandals are a great choice. When it comes to maintenance, clean the sandals with a soft, damp cloth regularly. Avoid using harsh chemicals as they may damage the materials. Also, store them in a cool, dry place to keep them in good condition. If you notice any signs of wear and tear, such as loose straps or a worn - out outsole, it might be time to replace parts or the whole sandal.
