I am a Virgo so I completely understand the utility of this question.
At class/workshops or dance practice I always wear athletic sneakers. I jump, stomp and shimmy a lot and it really improves and preserves your body.
When performing I just use whatever type of shoe I like be it high heel or boot and I add inserts, heel pads and non-slick sole adhesives. I just put them on the bottom of my shoes and its instant traction. Thats my little secret for doing backbends in high heels on wood floors. ;-)
