I'm guessing you probably thought I meant "Shows", but no, there are in fact 3D shoes making their way to the market. Nike have released a pair of Zoom Kobe VI 3D shoes for the upcoming All-Star Game.
Insane! Look at them, really, do we need 3D shoes? Who is going to put 3D glasses on to look down at their own shoes? Or have some mates over and tell them excitedly "come over here and put these 3D glasses on!" "yeah, now what!", "dude, look at my shoes!!!".
