(i know thisreply isn't directly in response to the above...)
I think running prosthetics are designed to bend to imitate that, though. I'm not sure how physically close it is (probably hard to judge compared to fully-bodied sprinters because there will be psychological differences when the brains figuring out how to run, so you wouldn't expect the same speed anyways).
I have to admit not watching the paralympics recently, but I'm pretty sure that the running motion for the sprinters, etc, is pretty close to fully-bodied.
The whole toes thing.... I think it's not so much about having something to do the physical work of toes, as it is about having 5 of these small, vulnerable digits. Albeit I'm not sure how useful it is to have seperate digits for toes in general (i.e. like balancing on rough ground).... I never remember doing anything specifically by moving individual toes playing football, at least.
Although that's maybe going a bit deep into the subject of feet.....
