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.
