Smartwool created the first Merino wool Hike sock,

but that doesn’t mean we’re done pushing the limits of how comfortable they can be.



Best-fitting. Highest-performing. Fit for any trail.

We pack these pairs with the very best sock innovations in every height and cushion level

to help your feet feel their best from start to summit.

In 1994, we invented the first-ever Merino wool sock—the Classic Hike. They are our origin story. The catalyst. The beginning.

And inspired wannabes worldwide by setting the standard of Merino wool performance socks.

Almost 30 years later, these socks remain an icon in the outdoor community and only refreshed in the name of sustainability.

Timeless terry-looped comfort to keep things soft on the toughest trails.

This sock changed the game and created a community of Merino wool addicts,

so we aren’t changing it anytime soon.
