The upper is made of black translucent Flyknit material. The weathered white Swoosh outline is printed on these uppers, extending from the toes to the sides. The black plush heel is foldable and can be worn hands-free. At the top of the heel is a Volt label marked “STEP” to imply the step-in function of the inclusive design. The internal lace mechanism realized by the front black “LOCK” and “RELEASE” labels further increases the convenience of wearing.
