I normally wear a 7.5 narrow. I also have a low volume foot. I ordered one size down a 7 B. OMG! They are crazy wide and big! They list as a 7B  but seriously it fits like a 8 super wide! It's great if you have a chubby wide foot! But not great for us narrow feet peeps! So sad, cuz the metallic purple is a great color, and the shoe  looks amazing and comfy...if only it would fit.
