The Unisex WIGWAM ARBOR NXT Mid Crew Socks are made for the trails. INgenius NXT zone lining prevents blisters by transporting moisture from your feet to the outside of the sock. The mesh instep provides added circulation. The reinforced and elasticized heel and toe provide cushioning and durability for those more demanding ascents. The Olefin liner adds strength and comfort to the sock. The merino wool outer is lightweight and provides additional breathability while keeping the moisture at the surface, to keep your feet fresh.
