To use these socks, simply put them on like you would with any regular socks. They're great for light hikes and day - long adventures. When it comes to maintenance, it's best to wash them in cold water to keep the merino wool in good condition. Avoid using harsh detergents as they might damage the odor - resistant feature. Also, don't put them in the dryer on high heat; air - drying is a better option. Make sure to check for any signs of wear and tear regularly, and if you notice holes, it might be time to get a new pair.
