I hadn't worn my dress shoes for a while, about two years in fact, and unbeknowst to me the foam of the heels was almost completely rotten out. On the way to the university, a number of pieces fell off, and once I got here and took a look, it was clear they were going to be unusable. A trail of foam pieces was following me....
....so.... a collegue is bringing some shoes of his for me to borrow. They might not fit the best, but they should work. Two of the members of my jury have already seen my socked feet and know the situation, so there's really no negative effect left in wearing out-sized shoes.
Sometimes all one can do is laugh!
