As other reviewers have said, these shoes are comfortable right out of the box and very cute. The problem I encountered is that every pebble I walked over adhered to the sole of the shoes so it sounded like I was walking on crushed glass until I could clean them off. I don't know if this is typical or an anomaly but it;s very annoying. Don't walk on a dirty sidewalk, other than that the shoes are fine.
I'm an avid flat-wearer because I've sworn off heels for the rest of my life following a running accident where I broke my foot. Needless to say, I've searched high and low for the best pair of flats that look AND feel great and these are it. I own brown and black and love both. They fit true to size. They need no breaking in period, either. If you're looking for flats, look no further.
