These are Spock socks. Allegedly they're a real, officially licensed product, but I'm always skeptical when the only picture available is a rendering and not an actual photo. Is it because they don't exist or because they look even shittier in real life? I wore socks with sandals to go get the mail this morning. You know what my neighbor said to me? "Put some pants on?" Haha, how'd you know? "Because you should have taken his advice."
Thanks to carey, who agrees those ankle socks with the little pom-poms on the back are even cooler.
