Your feet are not disposable sponges.
Why Not Just Buy the Cheap One?
Cotton socks get holes in three months and stink. Darn Tough's merino wool lasts years, fights odor, and has a lifetime guarantee—cheap socks don't stand a chance.
The Buy-Once Math
Six pairs of cheap socks cost $12 and last a year. Six Darn Tough cost $150 but last forever—and when they finally wear, Darn Tough replaces them free. Math wins.
