These New Balance safety boots are easy to use. Just unzip the YKK zipper to put them on and zip up when you're ready to go. For safety, always make sure the boots are laced up properly before using them. When it comes to maintenance, clean the 6' Premium Nubuck Leather Upper regularly with a soft brush to keep it looking good. Avoid exposing the boots to extreme heat or chemicals as this may damage the materials. If the outsole gets dirty, you can use a mild soap and water to clean it. Store the boots in a cool, dry place when not in use.
