I initially ordered my regular size in a medium, but had to return it because the shoe fits extremely tight in the width.  I sent it back the next day, and re-ordered a C-width.  The return went through immediately, and the second order and shoes literally arrived within a couple of days.  I was amazed at the fast service.  The replacement shoe fits perfect in the width.  I would highly recommend that if you are a true medium, you might need the wider width.  Apart from that, the shoe looks smart, can be casual or dressed up as other reviews noted.  I bought this style to replace a very good pair of black leather shoes that were worn well for at least 10 years, and finally needed to be replaced.  The only negative I can say is that these shoes are not great quality leather and likely will not stand up for too long, but for the price, you cannot expect them to last a decade.  It was difficult to find a shoe in the low heal style I wanted.
