What are the pros of driving barefoot?

My girlfriend always removes her shoes in the car and drives barefoot or in pantyhose. She says it's easier to control the pedal and feel more comfy like this. As most of people in Europe, she has a manual and has no problem pushing the clutch with barefeet. I would never do that because it would really hurt my feet but her feet has no injury.
If you do the same, what are your reasons?
