As long as you aren't causing any certain mischief, you'll be fine. It is acceptable to probably use it in this situation, given that your book may cause harm to others if you don't get it controlled. Your fellows nor the teachers will fault you if you were doing it for the greater good. That is, acquire your book and save your poor, abused shoe. Plus, ensuring the safety of your Housemates is always a good thing.
