The shoes could be outfitted with
tiny feedback mechanisms that would guide your feet to move left, right, forward, and backward.
It appears from paleo - science that there is more to it than that, the clouds that they generate as a control
mechanism on the earth's temperature, this is yet another
feedback mechanism for survival of all life on the planet and has been working for aeons of time, right back to the earliest life here... the planet was made more hospitable to life by life itself, geo - engineering on grand scale by the
tiniest of plants in the sea... which outstrips the cleverest of plans by humans to geo - engineer and more relevantly does no harm to the planet...
