Manufacturers Suggested Washing Instructions: Turn socks inside out, and machine wash in cold or warm water. Air dry for best results. If you prefer to use a dryer, use low heat only. Do not use fabric softeners. Fabric softeners will coat the wool fibers and reduce their ability to manage moisture and regulate body temperature. Do not use bleach or bleach additives as it will damage the fine wool fibers.
