If you've been watching gymnastics this year, you may have noticed something...
Some of the Olympic gymnasts wear socks!
Yeah, socks! During their floor routines!
"Why?" you might ask, and "Isn't that slippery?" you might wonder.
People are perplexed.
As it turns out, the slipperiness is kind of the point: It helps some gymnasts with turning elements in their routines. Chinese, Russian, and Brazilian gymnasts, among others, have worn them during the last week.
So if someone has a crazy-difficult turn in their routine, like this one from Aliya Mustafina at the World Championships in 2014, it helps a bit.
No socks here, though. Just sayin'.
Watch the women's gymnastics individual all-around final featuring Simone Biles tonight in primetime at 8 p.m. ET on NBC.
Aliya Mustafina competed in the World Championships in 2014, not 2004. Because she would have been like, 10 years old in 2004. Which would've been impressive.
