These Think Koak sandals are super easy to use. Just adjust the three straps using the hook - and - loop closures to get the perfect fit for your feet. You can wear them for a casual walk, a day out shopping, or even a short trip. When it comes to maintenance, avoid getting them wet in heavy rain as the leather might get damaged. If they get dirty, use a soft, dry cloth to gently wipe them clean. Store them in a cool, dry place to keep the leather in good condition. Don't bend or twist the sandals too much as it could affect the shape of the footbed and the durability of the outsole.
