I ordered 1/2 size smaller  as per reviews and the shoe fits well. The medium is wide and I hope the shoe doesnt stretch any wider.  The elastic back makes for easy on and no slipping out of the shoe.
 FYI They are made in china.  I didn't know this from reviews and if I had would not have purchased.  The mark up must be huge!  Buy USA*
I like the style and comfort even toe cleavage is cute.  Hope Chinese leather holds up will report after wearing for a few weeks.  I do not recommend shoe for jobs like nursing.  Not enough support for long term standing and or walking.
Great shoe for office job where your day is mixed with sit stand.
