These Josef Seibel Fergey 20 sneakers are super easy to use. Just slip them on like any other pair of shoes and you're good to go. Whether you're running errands or going out for a walk, they'll keep your feet comfortable. As for care, use a soft brush to clean the nubuck leather upper gently. Avoid getting them too wet, as it can damage the leather. If the insole gets dirty, you can remove it and wash it with mild soap and water. Let it air - dry completely before putting it back in. Store them in a cool, dry place when not in use to keep them in good condition.
