Granted; unfortunately, this particular sock happens to be Emil Zapotek's right foot sock, the one he wore in the 1952 Olympics. It can talk, but only in Czechoslovakian, and will only talk if you run long distance races. Otherwise, it treats you with utter disdain, and claims in broken English that Czechoslovakia should still be a country because "it is magický."

Granted; however, you find that you have no control over the speed you fly at. Good luck. I wish for the ability to disappear from existence at will.
