"I first got this in 7 but it's quite narrow at the front, so had to exchange for 7.5. I must say, the exchanged shoe was packaged pretty poorly compared to the original shipment. There were no stuffing paper in the shoe, the shoes were rattling in the box, not packaged well at all. The side straps also looked more flimsy and loose, maybe I got a shoe someone else wore a bit then returned. Anyway, it has great arch support and doesn't feel at all like a 4.5'' heel."
