Carbs, we can't live without them but atleast they are easy to burn off. The Air Channel Cushioning of the Carb uses an articulated foot bed to increase padding and airflow while a mosaic of mesh vents wraps from the top of the foot to the arch to further enhance breathability. Its 200 needle count stitching is paired with a reinforced heel and toe for a clean appearance and plenty of durability. For an unrivaled fit and exceptional support, this crew sock features anatomically correct designs for the left and right foot.
