The Buffalo Wool Co. Trekker Boot Socks

The Trekker is The Buffalo Wool Co.'s heaviest, warmest boot sock, made with a blend of bison down and merino wool. It's thick and well cushioned, with a padded terry loop footbed and extra yarn plaited into the toe, heel and lower leg for wear. The company says it's built to be worn with boots rather than as a house sock, and it's a good pick for cold days outside. The socks come in single pairs or three-packs. The product page says "Made in the USA."
