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 shaft 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.
Outer Nylon Plaiting
A more traditional sock construction technique that produces classic linear patterns and heather textures, outer nylon plaiting knits the stretch yarns in the outer layers of the sock and the body yarn on the inside. Reinforcing yarns woven into the stretch shell increase durability, while wool fibers sit closer to the skin for maximum insulation.
Bottom-of-Foot Cushion Zone
Found throughout our Adventure Sport collection and in some Adventure Hike models, bottom-of-foot cushioning adds shock-absorbing loop knit across the entire sole, from the toes to the heel. Cushioning here reduces impact from running and hiking, and the fitted instep won’t interfere with low-volume shoes.
Full-density cushioning features a terry knit loop on every interior stitch, providing better insulation, exceptional wicking, and increased protection against impact. Its faster moisture absorption keeps the skin dry and reduces friction, while its shock-absorbing nature enhances the performance of multi-sport and outdoor socks.
