"So then I could write with great confidance how we should not lower the heel to the floor untill the moving foot passes . But we should lower the heel to the floor imediately."
I got a better idea. Why don't you look at Jonathan's feather step right here on this website and tell me where his moving foot is when his right heel touches down (from toe only to flat) on step three?
Answer: not only is his left foot not closed, it has not even begun to move yet! All it's done is roll to the toe in preperation for moving. The actual closing of the left foot occurs only after his right foot is flat, while he lowers into his right knee.
Now, don't believe for a minute that ALL steps lower the heel this soon. But a lot of the lowering ones, especially the outside partner ones, should. And that doesn't contradict the book, because the book only gave you a full description of a walking exercise done inline, with no rise and no fall.
Oh, how's the search for the pause in the feather yet. Found one in that video?
didn't think so
