I'm a little confused on chapter 100?

On one panel Asa walks with shoes, then she goes on to check on her locker for "something" and finds her shoes to be trashed, and opts to walk home barefoot? What happened to the shoes that she had on? Why didn't she use them instead?

This confuses me more than the ending of part one, I NEED TO KNOW THE EXACT DETAILS OF ASA'S FEET LORE RIGHT NOW
