Using these men's derby shoes is easy. Just lace them up and you're ready to go for any casual or formal event. When choosing a size, don't forget to measure your feet length from heel to toe and match it with our size chart. This will ensure a comfortable fit. As for maintenance, keep them away from water and sharp objects. Clean them regularly with a soft cloth to keep the leather looking good. If they get dirty, you can use a mild leather cleaner. Also, store them in a cool and dry place when not in use to maintain their shape and quality.
