To use these Taos Lydia sandals, simply adjust the hook & loop closure to fit your foot comfortably. They're great for casual outings, walks, or just everyday wear. When it comes to care, avoid getting them too wet, as this can damage the leather. If they do get dirty, use a soft, damp cloth to gently wipe them clean. Let them air dry naturally, away from direct heat sources. Also, make sure to store them in a cool, dry place when not in use to keep them in good condition. And remember, since the measurements can vary by size, it's always a good idea to double - check the sizing chart before you buy.
