To use these sneakers, simply lace them up and you're ready to go. They're great for daily wear, casual outings, or even adding a bit of style to a semi - formal look. When it comes to care, use a soft, damp cloth to gently clean the leather parts. Avoid using harsh chemicals as they can damage the leather. If the rhinestones get dirty, you can use a mild soap solution and a soft brush to clean them gently. Store them in a cool, dry place when not in use to maintain their shape and quality. Also, make sure to measure your feet accurately before choosing a size to ensure a comfortable fit.
