Using these Dr Martens shoelaces is easy. Just thread them through the eyelets of your 8 - 10 eyelet boots in your preferred style. For best results, make sure to pull the laces tight enough so they stay in place but not so tight that it's uncomfortable. When it comes to maintenance, you can simply hand - wash the laces in cool water with a mild detergent. Avoid using bleach or harsh chemicals as they can damage the 100% Tetoron material. After washing, let them air dry. Keep these laces away from sharp objects to prevent any cuts or fraying. With proper care, these laces will keep your boots looking great for a long time.
