Watching Olympic gymnastics at Rio, you might notice that some of the athletes are wearing socks. It's not just you, it wasn't always this way. Think back to athletes like Dominque Dawes, Shannon Miller, Paul Hamm, or Dominique Moceanu. All performed floor routines barefoot. So why are Olympic gymnasts starting to wear socks? Is it because of toe fungus and gymnasts from New Zealand having hobbit feet?
While those theories have merit at the local Y, socks at Rio are all about performance. Socks "give you a better grip on an apparatus (kind of like chalk)," keep sweaty feet from becoming slippery, and, "help gymnasts get turns around on floor," according to The Gymternet. Others wear socks like Sole Impact Socks to help absorb some of the forceful impact routines can have on the soles of athletes' feet.
