I loved these shoes when I first received them, but have now discovered that after wearing them only FIVE times spread over two months, they smell HORRIBLE - this isn't something I have a problem with in other shoes.  If it wasn't for the fact that they appeared new, I would absolutely think someone with a severe foot odor problem had worn them for a month and returned them.  Something is seriously wrong with the material inside these shoes to cause this, and I only wish I was still within the return window.  I would NOT recommend purchasing these.
