To use these shoelaces, simply thread them through the eyelets of your casual shoes in the front-lacing style. When wearing, make sure they are tightened to your comfort level. For maintenance, clean them with a soft, damp cloth regularly to keep the synthetic leather and rubber in good condition. Avoid exposing them to harsh chemicals or extreme temperatures as this may damage the materials. Also, be gentle when handling the car suture details to prevent fraying.
