The SmartWool Azalea Crew Sock features a slightly scrunched top with a woven look for optimum fit and serious style. The supportive arch brace helps keep the sock in place, while strategic mesh zones offer ample ventilation so feet stay cool and dry. The Azalea Crew Sock incorporates SmartWool's WOW Technology into its reinforced sole to maximize durability, performance, and comfort. This non-cushioned crew sock is constructed from a rugged blend of 70% Merino wool, 29% nylon, and 1% elastane fabric. Made in the USA.
