What are those call

[Dark Knight]

OK this may sound a like a simple question we have all need asked when bocking.

Someone stop you and asks " What do you call those things ? "

I'm not talking about brand names I'm talking about the generic name    for spring loaded stilts   

I call them "PowerBocks" but Do.It.On.Bocks called them something else !?

So .... What should these things be call ?

[zipp]

i thought i read somewhere, that they are technically called "inertia stilts"??

[Athoul]

Jumping stilts, I know the welshies and many other people use this as its sooo simple to understand and its exactly what they are.

People are much more likley to remember jumping stilts rather than powerbocks in my opinion

I make it a point to refer to them as "jumping stilts" or "spring stilts" as the generic term -- and tell the curious (who are not actually interested in buying a pair) to simply Google or YouTube that term when they get home for more info on them.  It is easy for them to remember.
