As the founder of Spanx, Sara Blakely is used to being constricted.

But not on her feet.

Blakely told Footwear News about a hilarious interaction she recently had with first lady Michelle Obama, who she said gave her permission to go barefoot at the White House.

Blakely said she was was standing in a long line at an event to take a photo with FLOTUS when her Christian Louboutins became painful.

No one who wears heels all day dances like this. No one.

When she finally reached the first lady, Blakely said she "literally burst out, 'My feet are killing me,' and (FLOTUS) goes, 'Girl, my feet are killing me, too,' " Blakely told Footwear News, according to Huffington Post. "I asked if I can take my shoes off and she said, 'Yes, and you can tell anyone who tells you to put them back on that Mrs. Obama said you can take them off.'"
