LOVE this shoe!!  This is my second pair.  They are super comfortable, I can walk around ALL day without any issues with my feet, and my feet don't slide around in them.  The memory foam on the bottom is awesome!!!  I recommended to my sister and she was going to get them, however, they ran out online AND they were not available at the store we checked.  I guess they are pretty popular!  I can see why!  Anyway, I may even get a third pair as they are just that comfortable!
