To use these boots, first, loosen the laces if they're tight. Then, use the side zip to quickly slip your foot in. You can adjust the laces for a snug fit. When taking them off, unzip the side zip and pull your foot out. As for maintenance, keep them away from extreme heat and moisture. Clean them regularly with a soft cloth. You can also use a leather conditioner to keep the leather soft and prevent it from cracking. If they get dirty, use a mild leather cleaner and wipe gently. Avoid using harsh chemicals as they can damage the leather.
