Using these Merrell sandals is a breeze. Just unbuckle them to slip your feet in and buckle them up for a secure fit. They're perfect for all - day wear, whether you're strolling around town or hitting the trails. When it comes to maintenance, keep them clean by wiping with a damp cloth. Avoid submerging them in water for a long time as it might damage the leather and other materials. Store them in a cool, dry place when not in use. If you notice any odor, the Cleansport NXT™ treatment should help, but you can also air them out occasionally to keep them fresh. Also, check the buckle regularly to make sure it's working properly for easy on - and - off.
