7 leagues professional jumping stilts (as they are officially known) are something i've been hearing about for a while now. i saw a kid in bromley wearing them last year, but not using them to their full potential (in my opinion).
they are made of an aluminium frame and fibreglass springs, and some pictures i've seen of people using them to the max look amazing!
prices range from about £170 to about £250, which is quite a lot. i remember when micro scooters first came out they cost about that much though, so maybe these will get cheaper as popularity increases. i hope so!
