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.
