Prada beige flats size 39, worn twice

I love these shoes. They are so cute and go great with any outfit. However, in my excitement to purchase them in San Francisco, I seem to have purchased them a half size too small and they are just a little less than ideal for my feet. I wore them two times up and down the hills in San Francisco but feel I should sell them to get the larger size. Some light scuffs as shown in photos
