How to use: Just lace up these boots tightly for a secure fit and you're ready to start your work. Make sure your feet are clean and dry before putting them on. Attention: Don't wear these boots in extremely corrosive environments. If you work in wet conditions for a long time, take them off and dry them as soon as possible to avoid damage to the material. Maintenance: Regularly clean the boots with a soft brush and mild soap. After cleaning, let them dry naturally in a ventilated place. Don't expose them to direct sunlight or use a high - heat dryer, as this may damage the micro - suede upper and the insole.
