The leg is made of carbon fiber. Eric, the man who made his prosthetic, took us around his shop and showed us how it was done. It is so cool--maybe I ought to do a whole post on it. Steven had requested a thermometer in his leg and so Eric made a mold of this little keychain. He had of course, made a mold of Steven's leg as well. He put the carbon fiber over the foot mold and then he took the thermometer mold and adhered it to the leg in the place where he wanted it. Then he puts resin over the carbon fiber. He cut out the thermometer mold (had he used the actual thing, it would have melted). Then he glued the actual thermometer in place. Now, that is how I understood it, though I may be wrong--I am no expert here.
So yes, Steven also has a compass--and he just keeps brainstorming the gadget possibilities on future legs.
This leg seems to be a whole lot more straight than his old one. Straight as in, his backwards foot isn't out to the one side like his other leg. It has changed the way he walks, but I am hoping that with practice he will just keep getting stronger in the places where he is weak.
