These shoes are too big in the back and too tight in the front!  I put a gel sole in to keep the back from slipping up and down on my heel, but that only worked for the first hour.  They continue to slip up and down.  The front is tight and the top band cuts into the top of my foot when I walk.  I thought they would be ok to wear to work since I sit most of the day, but even having to walk across the office has now become painful.  I am sending these back, along with the seafoam pair I bought.  It's a shame, since they are such cute shoes.
