Using these Vans shoes is a breeze. Just slip your little one's feet into the shoes and lace them up through the eyelets for a secure fit. When it comes to sizing, make sure to check the USA Youth Sizing chart. For infants, the three - eyelet design will be a perfect fit, and for youth, the four - eyelet style will work well. As for maintenance, keep the leather clean by wiping it with a soft, damp cloth regularly. Avoid exposing the shoes to extreme heat or moisture, as this can damage the leather and the rubber soles. If the shoes get dirty, you can use a mild soap solution to clean them gently. This will help keep your Vans shoes looking great and lasting a long time.
