Smartwool invented the first merino wool performance sock, but they'll never stop trying to make it better. Classic Hike socks are getting upgraded and it starts with recycled nylon. The first-ever merino wool hiking socks are now made more sustainably than ever before. Light cushioning on the bottom of the sock and responsibly sourced, ZQ-certified merino wool offers comfort and natural performance benefits that help take care of your feet on every hike. With a mountain pattern and the same all-day comfort, the oldest (and best) merino hike sock may be your new favourite.
