Comfortable and breathable
Size: Medium, Color: Coyote Brown 4 Pairs
Super comfortable socks that breathe well in my Danner steel toes. Not a lot of shrinkage in the wash so they fit right over and over. Don’t slide down your legs.

Not enough underfoot padding
Size: Medium, Color: Coyote Brown 4 Pairs
Socks are well made but would be better if they had thicker padding under the toe and heal.

Very good quality for the price
Color: Green, 4 Pack, Size: Medium
My expectations of the quality was low. Surprisingly tho the socks were pretty good and the quality surprised me. They are soft and comfortable. Definitely recommend.

Great Military Uniform Socks
Color: Green, 4 Pack, Size: Large
Fantastic socks for USAF or other military uniform. I'm in uniform all day and these socks keep my feet from smelling and keeps them comfortable all day! Great quality as well!
