Tons more pictures in Japan-MMA‘s excellent Shinya Aoki – The Evolution of Tights post, plus the answer to something I’ve wondered for a while:
His Pride debut came against Jason Black. This was in Bushido 12, and I think this was the debut of the long tights.
Now that Aoki could be coming to Strikeforce, it’ll be very interesting to see how and if he’s forced to change his style without his magic submission pants.
