Award-winning performance worthy of Mother Nature’s best: Merino wool!
It’s been 15 years since SmartWool’s first hiking sock hit the trails. To celebrate, new this year, they’ve added WOW Technology™ to their classic Hiking, Trekking and Mountaineering socks. WOW Technology™ puts more wool in the heel, toe, and across the entire sole, to give you longer lasting wool benefits and more comfort.
