How to use: Just lace up these boots tightly before you head out, whether it's for military duty or other activities. The traditional lace closure allows you to adjust the fit according to your needs. Note that the dark coyote color is compliant with AR670 - 1, so make sure it meets your specific requirements. Maintenance: Regularly clean the boots with a soft brush to remove dirt and debris. After getting them wet, let them air - dry naturally. Don't expose them to direct heat sources as it may damage the materials. Periodically check the laces for wear and replace them if necessary. Also, the removable insole can be taken out and cleaned separately for better hygiene.
