get in this situation

what would happen if you suddenly break a shoe, you are in a bibliotrca and the sole of your shoes is peeled off and your foot is exposed, a few tables beyond, there is an area where there is a no shoes policy and there are many pairs next to the door, there are only 3 people in that room, one of them went to the bathroom, another falls asleep and the third person is on his cell asking questions in Similar Worlds. knowing that your house is 6km from the city, what would you do?
