To use these Keen Utility boots, simply put them on like you would any other pair of shoes. They're great for work or other activities where you need comfort and safety. When it comes to maintenance, keep them clean by wiping off dirt and debris regularly. Avoid exposing them to extreme heat or chemicals. If they get wet, let them dry naturally. For odor control, the Cleansport NXT™ will do a great job, but you can also air them out after use. Remember to check the condition of the aluminum toes and other safety features periodically to ensure they're still in good working order.
