The professional line of Stephanie dance shoes are in my opinion the best quality for the best price ballroom dance shoes available. The front of the shoe is super flexible, the cushioning is wonderfully comfortable, the satin is smooth and looks amazing. I have these in a 6.5 copper tan satin 2.5" heel, in street shoes I wear a 7.5, BUT I'm a dance instructor and can't live without my big toe hanging off the end a centimeter or two. Plus, I do have fairly narrow feet.. so I would recommend your street shoe size if you run wide or are not yet comfortable with your toes off the end.
I also added some swarovski hot fix crystals to these the color of the satin to give them some extra pizazz!
