When I bought this Ballerinas, I was thrilled until I have the shoes worn times throughout the day. The sole is very thin, flat and flexible, so that the shoes hardly springs on hard ground. After a time the heel hurt a lot and good for your back is not. After a few weeks they unfortunately lose their beautiful appearance. There they are already cut out a long way, the foot looks a little wider, but over time they lose completely their shape and support they offer their feet hardly more.
My conclusion: If the shoes are not worn more than 2 to 3 hours, they are ok and look nice from. But for long days, they are useless. It was nice to them, but again I would not buy me.
