 The moisture-wicking properties of the buffalo fiber keeps your feet dry, holds down any bad bacteria, and testing shows that your feet will remain 3 to 5 degrees cooler than in a traditional cotton sock. These bison socks are tough and extremely long-lasting as well. Crew socks, compression socks, boot socks, ankle socks, adult and kid sizes, all from the longest-lasting, hardest-working, truly insulating fiber that insulates the buffalo.
