When running, are ankle-weights harmful to the feet or legs?!

Question:
I frequently run and I have been thinking of using ankle-weights, but I'm not too sure if it is harmful or not. Any help would be appreciated.
Answers:
Not a good idea. Alters your stride and may overtax other muscles leading to possibility of injuries. Happy running.

Other Answers:
I've read that it's bad for your feet. The bones in your feet are delicate, and you'd be putting more weight and pressure on them. The article that I read (can't remember where, so I guess this isn't very helpful) said not to do it.

I don't think they would do any good, and they most likely might cause injury.
