Using your Merrell tactical boot is a breeze. Just unzip the heavy - duty medial zipper and slip your foot in. When you're done, zip it up. For daily use, these boots are great for various work environments. However, avoid using them in extremely harsh chemical environments as it may damage the materials. When it comes to maintenance, clean the boots regularly with a soft brush and mild soap to keep them looking good. Let them air - dry naturally, never use a heater or dryer as it can warp the materials. Polish the toe area to maintain its professional look. Check the laces and zipper periodically for any signs of wear and tear, and replace them if needed.
