SmartWool is proud to say that its socks are made here in the United States.
Make every step count with the Smartwool PhD line of Run Elite Socks. Light cushioning provides just enough padding for long runs on the pavement, while the merino wool/nylon blend naturally wicks moisture, regulates your foot's temperature, and resists odor-causing microbial growth.
Whatever your trail, the PhD Outdoor sock collection is made for mileage. Bi-elastic construction for focused fit, flex, and recovery create a sock that stays exactly where you need it to be. And our patented ReliaWool™ technology provides superior durability for socks that’ll go more miles than your shoes.
