These Sockwell women's leaflet socks are super easy to use. Just slip them on like you would with any other socks. When it comes to sizing, check the size guide to find the right fit based on your shoe size. If you're in between sizes, go for the larger one. For washing, you have two options. The easy wash method is to turn the socks inside out, machine wash in warm water, and tumble dry on low heat, but don't bleach them. If you want to be more eco - friendly and take better care of the socks, machine wash them in cold water and let them air dry. Enjoy the comfort of these socks made with a blend of Merino wool, bamboo rayon, stretch nylon, and spandex!
