Using these Keen Utility safety shoes is straightforward. Just lace them up using the secure fit lace capture system for a snug feel, and the KONNECTFIT heel - capture system will keep your heel in place. They're great for various work environments, especially those with metal detectors due to their non - metallic construction. When walking, the KEEN.ReGEN midsole will give you extra energy return. To keep them in good shape, clean the mesh and synthetic upper with a soft brush and mild soap. Let them air - dry. Avoid exposing them to extreme heat or sharp objects. If the removable metatomical PU footbed gets dirty, take it out and wash it separately. Replace the footbed if it loses its shape over time. These shoes are built to last, so with proper care, they'll serve you well.
