The Boulder is a traditional hiking sock that has exactly what you need: durability, comfort, and all-season versatility. Outer plaiting construction gives it durability and that classic hiker look, while placing more body yarn next to the skin for improved wicking and insulation. Full-density padding along the instep and up the calf makes it comfortable to wear with lace-up hiking boots. Last but perhaps most important, 100% American-grown merino wool provides excellent thermal regulation and natural resistance to bacteria and odor build-up.
