I found that these shoes ran on the small side and are narrow. Order a size up and you will be more than happy if your feet are medium to wide. I wear a size 6-7, depending on the shoe.  I have many pairs of Clarks they are my favorite shoe manufacturer.  Some are size 6W, others 6.5M and like this pair 7M.  They are comfortable.  The best investment I have made is in buying a shoe stretcher.  Amazon sells many affordable ones.  I recommend a wood one it will last a lifetime. I now can make any shoe fit as if they were custom made. And, in a way they are because they are custom stretched to perfection.  I did this with the Pirro Wedge and now the straps no longer dig in.  Oh, by the way, the color is a wonderful blue green, almost seafoam.  It looks great with blue or aqua.
