To use these shoes, simply slip them on. They're perfect for work in electronics, light manufacturing, or on assembly lines. When it comes to maintenance, use a soft brush or cloth to clean the leather upper regularly. Avoid using harsh chemicals as they may damage the leather. Keep the shoes in a dry place when not in use. As for the removable footbed, you can take it out and wash it gently with mild soap and water to keep it fresh. Be careful when walking on sharp objects to prevent damage to the outsole. And always check the ESD functionality if you're working in an environment where static electricity is a concern.
