The Fox River Wick Dry Maximum Mid-Calf (Boot Length) Socks are Fox River's most popular military-style duty socks. These socks are built to take everything your duty can dish out and leave your feet feeling as good as they can at the end of the day. The Wick Dry system ensures your feet stay dry, regardless of the conditions, while extra cushioning on the sole softens the heavy blows. Quick-drying polypropylene means your socks wash out easier and dry much faster. The URfit System (see below for more details) binds the sock around your feet, ensuring your socks stay in place - which means you can forget about blister-causing friction and focus on the more important things. The Maximum socks are perfect for warm weather.�
