To put on these Dr Martens boots, gently open the top of the boots and slide your infant's foot inside. Make sure the foot is placed flat at the bottom. When taking them off, hold the heel and gently pull the boot off the foot. Remember to clean these black leather boots regularly with a soft, dry cloth to keep them looking their best. Avoid exposing them to extreme heat or moisture as this can damage the leather. If they get dirty, use a mild leather cleaner. Also, check the boots regularly for any signs of wear and tear, especially around the seams, to ensure your infant's safety.
