This mid-rise performance sock style from the Fusion Athletic collection blends art and science together for a sock that looks as good as it feels. This sock features a blend of performance fibers that work together to move sweat away from the surface of your skin to help feet manage moisture, while specialized mesh vents extend from the top of the foot to the arches for extra airflow. To help manage the heat, the Crunch Crew sports a signature Air-Channel Cushioning design, while a graduated compression fit enhances circulation. For added durability during your longest days, each sport is built with a reinforced heel and toe and separate fit for each foot. Material: Polyester, Nylon, Spandex, Elastane.
