They're fly jumps, well they have fly-jump written on them and the ratchet bindings, unlike skyrunners. The reason for the stupid gnome listing is a copyright issue, these can be imported very cheaply from china as they have no copyright law's there. However there is a copyright in place here which makes selling them on for profit a bit tricky, I know this because I was planning to do it myself. So he's selling a gnome and giving them away for free, no law's broken as stated in the ad.
The only thing he's done wrong is not send me a gnome, I can easily get my money back now because he hasn't sent me what I paid for (as far as e-bay is concerned).
