Purchased this pair in black. It is to narrow and it does hurt my feet a little. Not sure about the heels though, because its to skinny and no support. Heels are almost like sitting in the middle of the shoes,instead of right on the bottom of the heels.  I find my self wobbling every time I slide it on.
I had to use the gel insert to keep it from pinching my feet,and its not enough cushion for comfort..Please keep in my I normally wear size 5. I cant imagine what it will do to a bigger size... Another bummer! No more purchasing shoe online unless I get to try it on in person!!!!!!!!
