Okay, so I've been dancing about a year, but when I get privates with an instructor I always ask to review my basics first. I want to make sure I'm not getting into any bad habits, and that I'm dancing in a way that facilitates easy movement/response (and thus my ability to follow the lead). Here's the problem; I have heard a few different theories on this particular movement. I took a class from one of the great salsa dancers and she said that my heels should rarely ever go down at all. It can go down only occasionally if my weight needs to be completely on that foot, but very very rarely ever on the back part of a basic, and even then very controlled so you can't hear my heel. She says that by pushing into the floor with my toes I am in better control of my weight and balance and can follow better. Then I take a private with another great instructor...he asked me why I didn't put my heels down, that I need it for correct weight transfer/pressure on the feet. That if I don't I am likely to knock myself off balance and that many people pitch themselves forward doing this. (The fact that I don't pitch my weight forward makes me very happy). I've had local instructors verify both these ideas...but inevitably the girls have said don't put your heel down and the guys put their heels down. (I've even seen guys here SPINNING on their heels). What are your viewpoints on this?
