These are so very comfortable.  I love the arch support and the deep heel cup. Wonderful support.  I would give them a 5 if it wasn't for the loud suctioning noise that happens when the arch of your foot lifts away from the shoe. They are rubber so your foot sticks to the sole.  I have been embarrassed many times now with people looking at my thinking I passed gas.  I have tried powder and dryer sheets rubbed on my foot or the shoe, but the sound is getting worse, not better.
