I love looking at feet--especially across a room.  When I see someone I don't know, I immediately register a technical score.  "How much dance training have they had?" I wonder.

Dancers' feet are especially interesting even when they are NOT dancing.  Do they carry what they learn in class into their everyday movement?  What are the big signals that a person has taken her--or his--technical training seriously?

Turned in, parallel, or turned out?
Look for this when someone is walking as well as standing.

Rolling in, balanced, or rolling out?
The muscles on the inside and the outside of the foot (and ankle) need to be strong enough to keep the foot in alignment.

Leading with the heels or rolling through the foot?
Dancers need to master the art of being on the balls of their feet.  The trickiest time seems to be as dancers are escalating to a leap, often digging into their heels because they think this will help them achieve power.

All three of these skills are critical.  It takes mental understanding, kinesthetic awarness, and a lot of repetition to create the muscle memory needed for this skill set, so dancers:  make sure you "work your feet--and they'll be fabulous!"
