These are polypropylene liners designed to prevent blisters by wicking moisture and keeping your feet dry. Liners increase the effectiveness of thermal socks and are normally worn under them to keep the feet warm, dry and comfortable.
Polypropylene is a non-woven textile that cannot absorb any moisture so instead it moves through the fabric from the inside layer of the sock to the outside where it evaporates.
In summer liners can be worn on their own as a light-weight moisture wicking sock.
It is recommended to wash these socks with cold water
