these are fairly true to size - I wear a 7M.  They are comfy on the foot bed but the heel area isn't that comfy - not awful but rubs a little even though they aren't tight.  They are pretty but I was so excited about getting them and they just didn't look as good on as they did in the picture - especially for the price.  I'm a big fan of Miz Mooz shoes and have many but these aren't a fav of theirs.  The green was true to color which I really wanted but they made my narrow feet look wide and they weren't comfy in the heel.
