"I haven’t danced in six months so I was full throttle at this spot," Spears captioned the video. "And yes …. I know I’m barefoot …. don’t laugh but I grip the floor better that way !!!!"
"PS you can hear where I broke my foot here ???," Spears added, referring to the somewhat gruesome moment at the end of the clip where she audibly shatters some of the bones in her foot. "Sorry it’s kind of loud !!!!!"
