Made in Vermont USA, Darn Tough Hidden No-show socks are excellent. I've always gone sockless in the summer, as was the fashion in the 80s. Nowadays I have sensitive skin on my feet, so I must wear socks. I've tried them all, and Darn Tough is the only one that stays put. Every other brand slips off the heel and bunches up in the toe.
They last forever, and have a lifetime guarantee. Merino wool is very soft, breathable, and comfortable. The fit is an exact match to the sizing chart, and they don't shrink in the wash. The price shocked me at first, but the quality, longevity, and guarantee make the socks a good investment. I would have replaced cheap socks a hundred times in the years I've been wearing Darn Tough. Plus, I'm thrilled to buy an American-made product!
