Well, I've never chosen who to dance with on the basis of her shoes. The only people I ever talk about shoes with or hear talking about shoes are followers, so I doubt it's especially high on the average leader's list of criteria. Excessive bum wiggling (beyong the natural movement due to weight transfer) would definitely put me off asking somebody to dance. My criteria would be: 1. Attitude - arrogant followers need not apply 2. Motivation - cold followers who seem to be there to make shapes (however technically good) are far less desirable than those who are there to enjoy sharing a dance (however inexperienced) 3. Posture - It's great if they can pivot without needing me for balance, although if they've got 1 and 2 right I'll care about this much less 4. Technical ability 5. Dress material - I don't enjoy the feel of artificial fibres. I remember one follower whose dress was commented on all evening by many other followers for looking especially good, but the multiple layers of artificial fibre rubbing against eachother as the embrace changed made for quite an unpleasant dance.
