In the video game series Portal, our protagonist Chell has three weapons at her disposal. She obviously has her wits and her portal gun, but she also needs to make sure that she's well taken care of in the event of a high-speed impact brought about by falls. Hence, the Long Fall Boots.

The boots were developed by Aperture Science after test subjects using the portal gun routinely fell from great heights. This was costing them a fortune in guns. The loss of life was a characteristically lesser important feature. With the boots on, even terminal velocity was no match for their cushioning powers, provided you landed on your feet, of course.

Inspired by the iconic footwear, enterprising designers have gone out of their way to develop their own versions. Since we are all about fashion at Art Attack, this is your guide to finding the perfect real-life Long Fall Boots.

Jared Sellers whipped up an homage to Converse with these knee-high sneakers. Modified from some of the comfiest shoes on the planet, Sellers has attached the famous Aperture logo and laced them with laces corresponding to the two-colored portals that Chell produces with the portal gun. Sellers has a whole line of video game-themed shoes, featuring Mortal Kombat, Metroid and Metal Gear.

Not yet on the market, but in development, Lyoko Nakadashi has put together a pretty impressive blueprint for a damn fine set of boots using a nice set of stripper shoes and professionally cosplayer know-how. Perfect for the short girl who'd like to add some height to her cyber look.
