Being light in your hiking boots is a glorious thing, and that's why you are faithful to the Smartwool Hiking Ultra Light Crew Sock. Merino is magical in the way that it manages moisture and keeps your little piggies at the perfect temperature all year long, and the ultra-light knit means this sock works well for warm days. A flat knit toe seam makes the threat of blisters less likely than the possibility of winning the lottery. Mesh ventilation keeps the fresh air flowing while WoW technology and an elasticized arch support keep your foot comfortable without adding heft to this barely-there sock.
