Using these Keen Utility hiking work boots is easy. Just lace them up using the locking non - metallic lace hooks and the secure fit lace capture system for a snug fit. Wear them for work in various environments, like those with electrical hazards or areas with metal detectors. They're also great for hiking. When it comes to maintenance, clean the full - grain waterproof leather and textile upper regularly with a soft brush or cloth. Avoid using harsh chemicals. After getting them wet, let them dry naturally at room temperature. Don't expose them to direct heat sources. Replace the removable metatomical PU footbed when it starts to wear out. And always check the outsole for excessive wear and tear. Keep in mind that the boots are designed for specific uses, so don't use them in situations they're not meant for.
