To use these Caterpillar work boots, simply put them on like you would any other boots. They're designed for work environments, so you can wear them on construction sites, factories, or any place where foot protection is needed. When it comes to maintenance, keep them clean by wiping off dirt and debris after each use. You can use a mild leather cleaner to clean the upper part. Avoid exposing them to extreme heat or chemicals. If the boots get wet, let them dry naturally at room temperature. Also, check the outsole regularly for wear and tear. If you notice any damage, it's best to replace the boots to ensure your safety.
