To use these shoes, simply lace them up and you're ready to go. They're suitable for various events, from formal to casual. When measuring your feet for size, use a ruler and measure from the back of your heel to the tip of your longest toe. Make sure to measure both feet and choose the size based on the larger measurement. For maintenance, keep them away from extreme heat and moisture. Use a soft cloth to wipe off dirt regularly. If they get wet, let them dry naturally at room temperature. Occasionally, apply a leather conditioner to keep the leather looking good and prevent it from drying out.
