Using these stylish Solid Black Genuine Leather Derby Shoes is a breeze. Just lace them up and you're ready to go, whether it's for a business meeting or a fancy dinner. When it comes to sizing, always measure your feet from heel to toe and match the measurement with our size guide to ensure a comfortable fit. For maintenance, keep them away from extreme heat and moisture. Regularly clean them with a soft, dry cloth to remove dirt and dust. If they get wet, let them dry naturally at room temperature. Once in a while, apply a leather conditioner to keep the leather soft and supple. Avoid using harsh chemicals or abrasive materials on the shoes as they can damage the leather. With proper care, these shoes will serve you well for years to come.
