Parasitic Power Harvesting - Dada Sprees Supreme Shoes
The Dada Sprees Supreme atheletic shoes have an unusual feature - a "spinnah" built into the outside wall of the shoe just above the ankle. When you put pressure on the heel of the shoe (when walking or jumping), the spinner moves. So, the shoe harnesses some of the ordinary energy of walking, and does something with it.
Thinking about Parasitic Power-Harvesting in Shoes? Okay, maybe not. But the idea of putting the ordinary energy of walking to work is used in the stillsuit from Frank Herbert's epochal novel Dune. The energy of walking (and other aspects of locomotion) is put to work recycling moisture for reuse.
Paul sat on the edge of his bed and began stripping off his desert boots. They smelled rancid from the lubricant which eased the action of the heel-powered pumps that drove his stillsuit...

How much power is available if you parasitize human walking?
"In previous studies it has been calculated that up to 67 Watts of power are available from heel strikes during a brisk walk (68 kilogram person, 2 steps/second, heel moving 5 cm.) This level of power extraction from walking would certainly interfere greatly with one's gait."
