Release date is Sept 18th but only one place is selling them and thats 1948 Nike sportswear in London, so I am assuming these are mega limited! No mention of how many were produced though sadly but given there is only one location selling them we can assume they are in tiny numbers!
Incidently, here is a pair of Dizzee Rascals own Nike ID, clear to see how much he loves his "Bubbles" LOL
