These flats are my new favorite shoes, and this statement is coming from a girl who has more than 80 pairs of shoes.  They are my favorite because they can be worn with just about anything.  They are patent (faux) leather, and they are extremely comfortable.  I wore them for 9 hours straight yesterday with no problems.  I love these so much that I am seriously thinking of buying a back-up pair.  I have only done that once in the 20+ years I have been buying shoes.  The fit is perfect for me.  I have a slightly wide foot (not wide enough to actually wear wide shoes) and need a shoe that has a toebox with a generous amount of space.  These flats fit the bill.
