Captain America may not be able to fly, but he sure looks like he's got invisible wings, sometimes. Fly through your next busy day in style in these Marvel Captain America Star Knee High Socks with Wings. These soft blue socks are knit with a star print, Cap's shield on the shin, reinforced red toes & heels, and the piece de resistance: Puffy 3D white felt wings on the sides of each leg, inspired by the white wings on the sides of the original Captain America's helmet in the comic books.
