Got them today, put them on and was surprised  how light and soft they are. Perfect fit. I was walking in them all day, very light and ninja quiet (a must in a house with a newborn).
At the end of the day I felt that I am getting a callus just above my heel, I guess the band that holds it so nicely around my narrow foot was rubbing against my skin. I think once I wear it for a week they will brake in and won't rub at all. In case they won't Im sure will let you know.
Also, I've got yellow, or "gold", so I am a little concern how to clean them.
