Pound the pavement into submission with the Reebok's new running shoe. The ZigTech Shark brings back the lightweight cushioning of the original Zigtech, but the radically overhauled styling creates a smoother running platform that provides maximum control and maximum comfort. Tiny pieces of specially engineered rubber dot the sole and heel, grabbing the ground no matter how slick the conditions are, giving runners amazing traction no matter the running surface.
