When on duty it’s critical to focus on your job and not your feet. A loss of concentration at the wrong moment can be catastrophic. Spending all day with wet feet & socks is uncomfortable and distracting. Socks made with polyester, nylon, acrylic or wool do not keep feet dry because their wicking fibers attract moisture and hold it next to the skin. Blisters are the most common foot injury and it’s likely that wet socks are the cause of most blisters.
