Jumping stilts

Jumping stilts, bounce stilts or spring stilts are special stilts that allow the user to run, jump and perform various acrobatics. Spring stilts using fiberglass leaf springs were patented in the United States in 2004 under the trademark "PowerSkip", marketed for recreational and extreme sports use. Spring stilts are often mostly made of aluminium. Using these stilts is also called "bocking" or "powerbocking", a corrupted version of the name of the stilts' inventor, Alexander Böck.
