The one size fits most 68% acrylic 30% polyester 2% spandex Superboy Knee High Red & Black Shiny Cape Socks remind me of the Red Sun of Krypton...bring it to me, Non! Oh, sorry about that folks. I thought I was Terrance Stamp there for a hot second. It happens to me every once and awhile but the people here are well prepared to handle it. The black bodied / red trim socks feature a semi sparkly Superman symbol and (here is the kicker) an immensely reflective red sewn-on cape. Purchase the Superboy Knee High Red & Black Shiny Cape Socks before me! Ack! I did it again!
