This may or may not help you out because I think that you are looking for a dressier shoe to be able to wear to work. Nonetheless, I LOVE my new balance mules. My son was born in August last year and it was so nice not to have to tie shoes in my last trimester and I could walk all around the city in these shoes.
They always have them for around $50 at the Nordstrom women/children sale, which just happens to start today. :-)
Good luck.
