Left at the lights DC! Flyjumpers are not skyrunners. They are the same as projumps. The "projump" factory is now called flyjumper lol
What sort of hoofs do you have? Do you have the bolt-on type or the other type? These are the types of hoofs. It doesn't matter what version as such. Just if they are bolt on or not.
http://www.pro-jump.co.uk/forum-images/projump-feet-variations1.jpgOnce you work that out I would email them. Tell them what you have/need and they should be able to help. I'm not sure if it would be economical for you to get just the hoofs sent over but I guess you could ask. They might not even send parts.
Other option if you have bolt-on hoofs would be to make some hoofs like jason's MK3 hoofies.

Naz should be able to give some more accurate advise.
