Made in Vermont, USA. Lifetime Guarantee. Manufactured by Darn Tough Vermont. 

Making socks in Vermont for over 45 years. Wide Open does one thing, and they do it better than anyone else. In a society that caters to straight and narrow sizes, they noticed that sock patterns and standards don't exist for wide legs and feet—so they've created them. 

Wide Open: "BODIES COME IN ALL SHAPES AND SIZES. SOCKS SHOULD TOO."
