These shoes are long and narrow. They are supposed to be 7M, but look & fit like an 8 narrow.The arch support is sewn into the side of the shoe and offers no support what so ever. I`ve bought Clarks shoes in the past and loved them. These look and fit like cheap knock offs....Very, Very disappointed in these. I had to come back and edit and lower my rating! These are the most uncomfortable flat shoes I have ever worn. I would return them but that is a big hassle where i live (very small town). I love Clark shoes and hate to give this bad review...but, I can`t even wear for an hour of sitting!
