Received these in the mail today, and immediately put them on and went for a walk.  Very comfortable!  I love them!  I usually wear a size 8, but after reading other reviews I decided to order a 7, which was perfect.  Definitely order a size down. Also, another reviewer commented that these would be great for people with wide feet because they were too big on her.  My feet are just average width, and ordering a size down will probably take care of any sizing issues for most folks.  Wide width folks might consider ordering their true size rather than a size down. They did rub a tiny bit on the back of my heel, but I have sensitive feet and these are no where near broken in.  With a little time to break them in, I can easily see these becoming one of my favorite pairs of shoes.

Edit:  After a year and a half of infrequent and very light use, the plastic buckle in the back has snapped, making it impossible for me to secure the heel strap.  The shoes are still comfortable, but unusable because they no longer stay on my feet with a non-functioning heel strap.  Huge bummer.  I wish there was a way to repair them.
