SmartWool Features & Highlights


Run Elite Socks

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.

SmartWool PhD Socks

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.

The SmartWool Advocacy Fund

The SmartWool General Advocacy Fund supports non-profit organizations that get kids into the outdoors while educating them about environmental stewardship. Since 2005, more than a million dollars has been raised and granted through the e-commerce outlet, which has provided 100% of the SmartWool Advocacy Funds since its inception. Through your online purchases, you have helped us donate more than a million dollars to organizations like The Womens Wilderness Institute and Outdoor Outreach, among many others.

Made in the USA

SmartWool is proud to say that its socks are made here in the United States.
