The muddier the trail, the better when you're wearing the SmartWool Striped Hike Light Crew Sock. But when spiffing up is required, the light cushioning and classic style of this sock make it equally at home in town as it is on the trail. The flat-knit toe seam allows the foot and sock to flex without bunching. The elasticized arch brace provides additional support where you need it most. Sizing clearly indicated on the sock. 57% Merino wool, 41% nylon, 2% elastane blend. Knit in the USA of imported yarn.
