I'll give you a minute to stop nerding out over these Portal shoes…
OK! Now that you've calmed down; the details, let me tell you them. The guy behind these tres chic Portal themed shoes is Mr. Jared Seller. Seller has been working on video game themed shoes and this pair is his centerpiece. Notice that the laces are mismatched, on purpose of course because what's Portal without blue and orange right? Now you youngsters can be mismatched without the ridicule of your peers. (at least from the ones who have played either Portal or Portal 2)
You can also see more of his shoes and more of his artwork at his web page here. Spoilers! There are Super Metroid shoes, Mortal Kombat, and even Star Wars shoes and boy are they pretty.
