To use these sneakers, simply unzip and untie the laces to put your feet in, then adjust the laces for a snug fit and zip them up. When wearing, they're suitable for various activities like walking, shopping, or casual outings. For maintenance, clean them with a soft, damp cloth to keep the patent leather looking shiny. Avoid exposing them to harsh chemicals or extreme heat. If the laces get dirty, you can remove them and wash them separately. Store them in a cool, dry place when not in use to maintain their shape and quality.
