To use these Point6 merino wool hiking socks, simply put them on like you would with any other socks before heading out for a hike. Make sure they fit snugly around your feet and calves for maximum comfort and support. As for care, it's best to wash them in cold water on a gentle cycle. Avoid using bleach or fabric softeners as they can damage the wool fibers. After washing, lay them flat to dry instead of putting them in the dryer, which can shrink the socks. When not in use, store them in a cool, dry place. These socks are built to last, but following these simple steps will help maintain their quality and performance over time.
