Of course. But there are some follows who lean unbidden, who hang off their leads, etc. Those I avoid. And I have danced long enough (almost daily for 9 years) that my eye can usually discern if there is a lean or only an illusion of one when I watch others dance. I can similarly, not always, but often, tell when a lead is comfortable with weight sharing and has either initiated it or is at least happy with a follow's desire to share weight, and when he is dealing with unwanted weight. If I am just walking with a "simple" tango walk in parallel feet, my heel strike coincides with the initiation of my weight transfer, which creates the body lead for a follow's weight transfer. I can clearly lead the weight transfer in many other ways, but there are some follows who short step, even if I am leading a long step in a simple tango walk, that is, I have not yet transferred my weight and am still pushing forward. So, although as a follow you may not think in terms of the lead's heel being planted, as a lead, I certainly do. Whether I walk heel first or toe first, it is when my heel hits the floor that my weight transfers. Unless I decouple my body motion from my weight transfer, that is when I expect the follow to "land" her foot. Not before. This actually brings up an interesting point. Lead think verses follow feel. For example, if I am leading a turn, I do not think "rotate my embrace counter-clockwise" or any such thing. Instead, I might think "maintain the embrace and execute a smooth, controlled, lapiz." No, the follow will not cue off my lapiz, but, hopefully, if I do this right, she feels my chest and embrace rotate. For me, this is true for many other tango movements. As a lead, I may think in terms of steps, or body position, or whatever. Indeed, that is of no concern to the follow. Her/his only concern is how the embrace feels and where it is going. With enough experience, my "lead-think" translates into smooth, comfortable movement of my embrace, and hence into "follow feel". Thus, and I apologize for any misapprehension, when I spoke of "heel strike", that was my "lead-think" for weight transfer in a simple tango walk.
