So what makes our hiking and trekking socks so unique? We’ve combined generations of made in the USA craftsmanship, the latest sock science and lots of field and lab testing to develop this new collection of Merino socks.
Primed for every adventure from morning hikes with the dog to multi-day escapes, PhD® Outdoor socks offer best-in-class fit, comfort and durability. Featuring Indestructawool™ technology, a patent-pending, merino wool-based durability construction, they’re made to outlast your greatest adventures.
PhD® Socks represent the highest degree of performance. We pack these wool socks chock full of smart features, advanced technologies and dialed fit systems. They’re hiking socks that help you forget about what you’re wearing and focus on the trail ahead. Because you’ve got miles to go, and you couldn’t be happier.
We released our first Merino hiking socks back in ’94. Since then, we’ve added styles into the line for every type of adventure, but the heart and soul of our outdoor socks remain the same: they deliver ultimate comfort and durability whether you’re trekking around the world or walking around the block. There’s a PhD® Outdoor sock for every adventure and any boot.
