"But, be warned, if you’re interested in taking up this sport, you need to know that no-one can agree what it should be called. The equipment is sometimes referred to as power stilts, jumping stilts, spring stilts, kangaroo boots and many more. And then the various brand names include Powerisers, PowerSkips, Pro-Jumps, Fly-Jumpers, Air-Trekkers and PowerStriders. But there seems to be general consensus that the sport ought to be named Powerbocking in honor of its inventor, Herr Boeck." - Michael Mucahy, Powerbocking: jump like a kangaroo, run like a gazelle & stride like a giant, gizmag.com, 27 July 2009.
