Changes in momentum and pressure and excess foot heat are all used to generate electricity.

At the press of a button, the shoes shift into high gear. Using this electricity, they give little mechanical lifts to your heels at the proper point in the stride, making walking easier.

I can't confirm if this is the same as the spring walker as spring walker's web site is down. [Aristotle, Mar 22 2001, last modified Oct 04 2004]

       This guy's springwalker allows him to conserve the energy dissipated to the ground as you step and conserve it in the spring exoskeleton. Same concept as yours, but mechanical, not electrical. Plus it allows much larger strides.

       Wes -- I checked out that link, and watched the video. The guy sort-of looks like a giant Chocobo from FF. Looks fun... I'd want to make sure I had medical insurance before hoping on one of those babies, though.
