These Dr. Martens boots require no complex setup; simply lace them up to your desired tightness. They are designed for adults with a regular foot fit, making them compatible with standard sizing. To care for your boots and ensure their longevity, clean them regularly. Use a damp cloth to wipe away dirt and grime. After cleaning, apply Dr. Martens Wonder Balsam. Use the provided sponge applicator to work the balsam into the leather, which helps to nourish, protect, and restore the leather's natural luster and softness. This routine will help prevent drying and cracking, maintaining the unique textured look of the Ambassador leather.
