Portal 2 Investment Opportunity Video 4 April 12, 2011

The fourth (and probably final) Portal 2 Investment Opportunity trailer has hit the web.  This one is detailing the newest technology in footwear.

In the original Portal game, the protagonist walked around barefoot with these stylish walking prosthetics attached to her leg, which I immediately took as some new futuristic form of high-heeled shoe.  It turns out, that this is why in the game you can fall incredible distances and not have your legs rip off your body.  The shape was strikingly similar to the prosthetics worn by Special Olympics runners who have lost their legs (I believe they were modeled after the legs of bipedal animals).

Well, now they’re adding a boot to it!  You can check it out here.

Portal 2 is releasing April 21st, 2011 for PC, Xbox 360 and PS3.
