Girl group Sistar member Hyo Rin's barefooted performance is becoming an issue.

Recently on a online community a video of Hyo Rin from 2011 September performance in Lee Hwa Women University was posted.

In the video, Hyo Rin's heel broke in the middle of performing 'So Cool'. Hyo Rin, who looked a little taken back for a while quickly went to back of the stage to take off her shoes and got on the stage again, to the cheer of the audience.

Netizens who saw the video commented "wow only Hyo Rin could", "such a performer", "Her foot must have hurt from performing bare foot", and etc...
