Using these laces is easy. Just thread them through the eyelets of your outdoor shoes or boots as you normally would. When tying, make sure to pull the laces tight for a secure fit. As for maintenance, since they have low water absorption, they dry quickly after getting wet. But if they get dirty, you can wash them with mild soap and water. Then, let them air - dry. Avoid using harsh chemicals or abrasive materials as they might damage the laces. Keep in mind that these laces are designed for outdoor use, so they can withstand a lot of wear and tear, but don't subject them to extreme forces that could break them.
