foot pegs (folding)
 

I am looking for some foot pegs for my bike, preferably ones that fold up and attach in the rear to the axel, I have typical mountain bike style bike I want them to be low profile and not stand out or get in the way, have been looking with little success.

I found these but they attach to the fork in the front not the rear:

or these which attach to the axel but don't fold up:
