These legs are also being experimented with and trying to be advanced to be comparable with meat legs. Legs are much more difficult to recreate as leg muscles are more complex to manufacture for a prosthetic. Even so the legs have evolved to include more joints and allow for more functionality than just the early straight and unbendable prosthetics used before. A curved and more bendy model can allow the user to run, ride bikes, and move a lot easier. Prices for these legs can range from 5000 - 50000 dollars. They are also known to experience damages that may call for a replacement to be made multiple times throughout a lifetime.
