Using these socks is a breeze. Just pull them on like any regular pair of socks, and the stretch - to - fit system will adjust to your foot size. For cycling, hiking, or other activities, they'll keep your feet comfortable. When it comes to maintenance, machine - wash them in cold water and tumble - dry on low. Avoid using bleach as it can damage the fabric and the colors. Also, don't iron them as high heat might affect the stretchy parts of the socks. With proper care, these socks will serve you well for a long time.
