The Sub-Z Knee High Merino Socks are designed for hiking, hunting and adventuring in cooler conditions. The added length of these socks provides extra warmth for your lower legs. Our Sub-Z range of Merino socks have been carefully crafted to provide the ideal blend of warmth, breathability, durability and comfort you need in the outdoors. These socks have reinforced heel, toe, and sole areas, providing cushioning and extra support where you need it most. We've also added breathable panels that allow for better airflow and ventilation so that your feet don't overheat or end up swimming in sweat when the going gets tough. The natural temperature-regulating and moisture-wicking properties of Merino also support all-day comfort and help prevent blisters from developing. These socks are extra long and fit just below the knee. If you're after a classic crew fit, check out our Sub-Z Crew Merino Socks.
