Taking care of the Athletic Socks is simple, and following some easy steps will help you get the most out of them. Machine wash your socks in cold water, no warmer than 30 degrees Celsius (86 degrees Fahrenheit), or wash them by hand under cold water to achieve longer durability. They are safe to be pre-treated with fabric softener and stain remover to remove even the toughest of stains, but cannot be treated with bleach or be boiled. Once washed, we recommend hang drying them for the best results.
