Why are my feet peeling?

The other week, my feet were very raw and tough from wearing flip-flops for the beginning of the summer. So, as a solution, I used my PedEgg and then I put Dr. Scholl's Overnight Foot Cream on my feet and went to bed. The next morning, I woke up and my feet were slightly softer, so I was satisfied. This past week I have been working at an outdoor camp where I wore my Converse every day. I noticed yesterday that my feet are disgustingly peeled and there is a lot of loose skin. How do I fix this? With a pumas stone? Help me please! I have a date on Thursday and I really wanted to wear strap heels. Help?
