This site is dedicated to gadgets, gear, tools and any kind of devices used in sports in general.
I've explored this site and found some fun and interesting things..... who couldn't use a pair of FlyJumpers Jumping Stilts??? They could be very helpful to runners everywhere. Here is what they claim:
"Run faster than 20 miles per hour, jump 6 feet in the air, take 9 foot strides… without bionic implants."
Granted, some of the items are outdated (posted in 2006).... but fun none the less!
