These Keen Utility men's work boots are great for work environments. To use them, simply lace them up using the locking metal hooks and eyelets. When wearing, make sure your feet are well - supported by the 90 - degree heel and the TPU torsion plate. The boots are waterproof, so you don't have to worry about getting your feet wet. But avoid submerging them for long periods. For maintenance, clean them regularly with a soft brush and mild soap. After cleaning, let them dry naturally away from direct heat. Check the steel toe regularly for any signs of damage and replace the boots if the steel toe is compromised. Also, if the reflective webbing starts to fade, it might be time for a new pair for your safety.
