Our Trekking COOLMAX® socks combine CORDURA® and COOLMAX® technologies to provide a highly durable sock that will keep your feet dry and warm all day long. The CORDURA® delivers excellent strength for long-lasting wear, while the COOLMAX® is designed with a unique moisture wicking action to draw sweat away from your skin. The breathability and quick dry qualities also help to reduce the risk of blisters or hotspots during your hike or trek. The high crew height sock also features a heavyweight feel that is ideal for long days on your feet with a pack, with zoned elastic providing a superior fit. For further comfort and protection, there is a double heel and reinforced cushioning on the foot and calf.
