These I purchased as my backup shoes for our reception  when my feet started to hurt from my other high heels.  These are VERY comfortable and I have worn them several times since.  They slip on a little tough, but since they are only stretchy (no buckle) there should be a little resistant so the elasticity isn't lost.  I had enough space for my foot to fit through the bottom strap and it did not cut into the sides of my foot at all.  I would recommend these for purchase.
