To use these hiking socks, simply put them on like you would any other pair of socks. They're great for all kinds of hiking activities. When it comes to care, it's best to wash them in cold water to keep the merino wool in good shape. Avoid using harsh detergents as they can damage the fibers. After washing, let them air dry instead of putting them in the dryer. Also, make sure to store them in a dry place. If you notice any signs of wear and tear, it might be time to get a new pair to keep your feet well - protected during hikes.
