Great socks
Size: Large, Color: (002) Black / Black / Castlerock
These are the only socks I’ll wear when working. They are so soft and comfortable. They are thick and heavy duty, and don’t wear fast. The fit snug and perfect. Good warm with a little compression for being on your feet all day.

Good boot sock
Size: Large, Color: (001) Black / Black / White
Used these for over a year now. They cover your calf and really don’t move from that spot. Very comfortable.

Okay But Not Worth The $$$
Size: Large, Color: (390) Marine Od Green / Marine Od Green / Baroque Green
Standard athletic sock. Cheaper ones are available through soooo many sources. UA seems to mean more expensive.
