The American Trench Wool Slub Crew Sock in Navy is made out of a cotton-wool blend with a slub yarn that creates the speckled/grainy appearance. Slight ribbing at the top will help keep the socks riding high. These do have a slightly thicker feel to them, and we would consider these a medium-to-thick sock, best worn with boots or sneakers. These may be a little thick for dress shoes.
Note: One size, fits sizes 8.5-12. Machine-wash, tumble-dry low or air dry.
