I have really become a fan of Capezio's dance shoes. I feel like they are very well made and their customer service in unlike anything I've ever seen. Amazing!!

I wear the Sofia in a 2.5" heel. I'm very pleased with them.
Also, Showtime sells very high quality brands. They are a bit pricier, but tend to be well worth it.
