To use these socks, simply put them on before you head out for skiing or snowboarding. Make sure they fit well in your boots. When it comes to care, it's best to wash them in cold water to keep the wool and elastic in good condition. Avoid using harsh detergents as they can damage the fibers. Hang them to dry instead of putting them in the dryer to prevent shrinking. Also, check the socks regularly for any signs of wear and tear. If you notice any holes or loose threads, it might be time to get a new pair.
