What are the best dance shoes?

We are having a hard time finding dance shoes that stand up to tough choreography.

I don't know much about dance shoes, but we have, for the most part, been using Capezio Jazz sandles. They tend to start falling apart after 2 weeks of performances. That seems to me to be sub standard, and Capezio is a big name in shoes (right?)

Does anyone have any suggestions about how, and where to source out some robust, high quality dance shoes that will last an 8 week run?

Any help is appreciated
