These are very cool shoes.  They were comfortable from the first minute I put them on, and, interestingly enough, did NOT make me have blisters as new shoes of this type normally do.  I attribute that to the fact that the uppers on these are made of this really stretchy woven material, so they have quite a bit of give as far as molding themselves to your foot.  I work a 9 hour day at a standing workstation, and I can wear these shoes all day long without a problem at all.  And they kind of have a mini-wedge to them, so that is nice - I can't wear high heels any more, but, being a short person, I like any shoe that can give me a little bit of heel without killing my feet.  These can do that.  I'm thinking of ordering another pair in a different color, they are that comfortable!
