The Air Jordan 4 “Tech Grey” was perhaps a teaser by Jordan Brand as it gave us high hopes believing it was the original Air Jordan 4 “Cement”, that re-released over 10 years ago. However, regardless of the change, Jordan connoisseurs are still looking forward to this Air Jordan 4 Retro due to it’s close similarity to the actual Air Jordan 4 Retro “Cement Grey”. The “Tech Grey” Air Jordan 4 releases on February 18th 2012 and here we have new photos you can check out. Via kickz
