These shoes run very large. I wear 10W (I am more like a 10C), but these were so big I could walk right out of them - they felt more like an 11...I am wide across the front of the foot (from going barefoot for so many years) and my arches have fallen quite a bit. I noticed on one shoe it bulged out on the inner side of my foot.  They seem like they would be very comfortable (the padding in the soles) and they were cute - I wanted them to fit so badly! Unfortunately I had to send them back...(I took one star off for the size, but if they had fit they would have been 5 stars.)
