These Sockwell men's socks are easy to put on. Just slip them on like you would any other socks. They're designed with a relaxed fit, so they're super comfortable all day long. When it comes to sizing, forget about the tape measure. All you need is your shoe size. Check the size guide to find the right fit. If you're between sizes, it's best to go up a size. For washing, you have two options. The easy way is to turn them inside out, machine wash in warm water, and tumble dry on low heat. Just don't bleach them. If you want to be more eco - friendly and take better care of your socks, machine wash them in cold water and air dry. These socks are made with a blend of Merino wool, bamboo rayon, stretch nylon, and spandex, so they're soft, breathable, and stretchy. Enjoy your comfortable socks!
