I've tried peep and close toe shoes, and they just hurt my toes. So I'm going back to open toes. I hope I don't entirely regret it...a stepped on toe is just about the most unfun thing you can do in dancing...and it always happens to the one toe I really don't want it to happen to- my big toe.
But-nerves aside- the shoes are gorgeous and Greta Flora has quickly been gaining a good rep.
Here's a preview of a pair I'm considering in purple.
