These are very thin shoes. They kinds bend towards the inside so your feet look angled towards the inside. Which is a little weird. They don't breathe too much so my feet sweat a lot when I wear them. But they are super comfortable. I did not get any blisters at all. They did not slip off of me also. If only they would not make me sweat so much I would give them a 4 even if they make my feet look all curved.
