Wow, so that is what it's called, one day after school, it rained and there was floods my shoes were soaked, they didn't dry by the next day, and i didn't have another pair so I had to wear it to school by the time i was back from school, the sole of my feet were swollen and spongy, it was horrible to look at, i couldn't feel the floor, pain or anything whatsoever, it took almost three years for it to heal completely.
