Ready to become the bionic man? Just strap on the Poweriser extreme stilt boots and you'll be able to jump up to 6 feet in the air and run over at 20 MPH. The extreme sport is known as "Powerblocking" and it has taken much of the world by storm.

The 'Powerblocking' boots or 'Powerstilts' were invented by German aerospace engineer Alexander Boeck. Alexander studied the movements of kangaroos in order to develop his original prototype, which he patented in the U.S. in 2004. The design of the Powerblocking boot essentially allows the user to extend his or her Achilles tendon to the approximate length and power of those animals like kangaroos and Ostriches and mimic their amazing ability to jump. Similar to a trampoline, the powerblocking design accumulates, stores and then returns the energy put into them. Each boot consists of a foot-plate with snowboard type bindings, a calf-cuff which fastens just below the knee, a rubber foot pad which is also commonly called a hoof, and a fiber glass leaf spring. Once strapped on, the 3 foot long springs use the body’s own weight to generate power.

The boots pictured here from Poweriser, are just one of the many, that have sprung up from numerous companies using Boeck's patented design. The Poweriser boots range in price from $299 for the kids model, to $489 for the advanced adult size. Each boot is slated for various weights and proves to be a tremendous aerobic workout, unlike any other.
