I have purchased Aerosoles in the past and were very happy.  Now that I've started a new teaching job, I decided to purchase a couple more pairs to be stylish and comfortable.  The first time I wore them, I found them to slip off the back of my feet a little, AND poke out on both sides of my feet when I walked, but they were so cute I decided I could deal with that.  Then after a while, they started hurting my feet on each side just below my toes.  I thought maybe I just needed to break them in a bit.  No such luck!  I tried to wear them a second time and I couldn't even keep them on my feet for 30 minutes.  They were slipping off AND hurting my feet really bad.  Sad part is I only wore them ONCE, I'm an Amazon employee, and the site says I was supposed to return them by July 18th, 2015!!! Now I'm stuck with this shoe and the silver and white loafer!!:-(  Even though I'm an Amazon employee... I'm stuck with shoes I can't wear, and I'm out of $100 BUCKS!!!  Not good!
