The J.B. Field's Wool Weekender contains the highest amount of merino wool out of any sock we make. With a loose-knit and lightweight construction, these socks are breathable and made to fit into a dress shoe, but its exceptional softness will make you want to wear them all day long! With only 4% Nylon in its construction, they are non-binding and great for diabetics or those that prefer non-elastic socks.
