I tried this shoe on in the actual store to decide if I like it. I fell in love and followed the product online and in store for the cheapest price. When it shot down, I happily ordered. Unfortunately, I believe I received a defect pair. I am a size 8, slender foot. The inside of the shoe is loose and comes out/moves. It will actually scoot as I am running where my toes feel the fabric wrinkle. The back of the shoe is supposed to also have a foam support in the heel - which it does but it is not attached and will slide down into the bottom of my heel. I basically have to hold the insides of the shoe in place when putting these on...
