Where can i buy Code M shoes, the ones with built in speakers?

Ok so i was looking for some cool shoes on the internet and i came across the Code 5 shoes from Dada Supreme only you can't buy them directly from the Dada Supreme website. I looked at the FAQ's and it said you can buy them at big retailers like Journeys, Footlocker, Finish Line, and Underground Station. I went to all the websites and there was no sign of Code 5 or Dada Supreme. Can someone tell me anything about how to find these shoes? Thanks a lot
