The Operatus Athletic Sock's Coolmax moisture-wicking knit chassis accelerates the evaporation of perspiration helping keep you cooler and drier. The vented instep helps further reduce heat. The sock's compression helps to increase recovery and reduce the achiness and fatigue of physical training. Overall comfort is enhanced with a cushioned footbed and embedded arch support to reduce felt impact. Enhanced with ScentBlock anti-microbial treatment to prevent bacteria formation and odor.
