These Merrell women's sandals are super easy to use. Just adjust the top and back straps using the hook and loop closures to fit your feet comfortably. They're great for all sorts of activities, whether you're taking a walk in the park or going out for a meal. When it comes to maintenance, use a soft brush and mild soap to clean the upper part. Let them air - dry away from direct heat. Avoid wearing them in very rough or abrasive terrains to keep the outsole in good condition. Also, if you notice the straps start to loosen over time, just tighten them up using the closures. Enjoy your stylish and comfortable sandals!
