Darn Tough

Darn Tough socks are knitted in Northfield, Vermont, from fine-gauge merino wool with a high-density knit that holds up under boots, bikes and running shoes. The merino regulates temperature and resists odor, the seamless toe stops rubbing, and the construction is so solid that the company backs every pair with an unconditional lifetime guarantee: wear a hole in them and they send you a new pair.
