Powerisers/Jumping Stilts

Powerisers or Jumping Stilts.....They are a specially designed pair of shoes that you wear that have spring-kind-of-things on them. You can jump six feet high with them and run up to 20 mph! Pretty amazing! But my question is if anybody would know how to build them, or where to get them cheap, or what are the spring parts made of? Because the springs have to be under enormous pressure to withstand the bouncing. So if you know any material that would to the same trick please let me know.

Actually, I remember seeing a design somewhere, with someone using a parallel hinge system and some pulleys with bungee chords for a substitute for the spring. Think of the standard system, but instead of a rib-shaped spring on the back, there would be two pulleys and a bungee chord. I was thinking about doing some sort of this, because I am lucky enough to have a pair of powerisers, but I am getting a bit big for them, so it's either buy a new pair of make a new pair. I'd love to make a new pair, but there could be a lot of safety hazards involved. Regardless, pretty cool stuff.

Might of been said but someone has made their own, he called them bionic boots.

for the spring you can use the front half of skis.

would a fiberglass bow work?

Has anyone ever considered using a pair of "snapping" (non-lacing) inline skates as the foundation for this? I mean you can mount the "leg" to one of the wheel axles, the "spring bar" to the back of the calf and meet back on the "foot". Maybe even use the wheels as the feet ( 2 next to each other and disabled spinning)? I've seen Square metal bars at the hardware store with holes in it ala street signs, would this be strong enough? You could run bolts through it buy various brackets and presto! Only problem would be a DIY spring/tension bar?

I know this is an old thread, but just thought I'd add an interesting note about these things.
You need to have a pair that suit your weight. My daughters belong to a local circus and the circus have some of these, but my elder daughter is only very slight and doesn't have enough weight to make them work lol.
They are really cool to watch.
