I would suggest if desperate for a bruin, then get the White Blue Bruin QS or Tier Zero i think they are called?
They also seem to be in pure white and also a white with black.
Maybe the pure white would be easier to paint onto, but from the pics they are identical to the limited Mcfly release, just the swoosh and heel are different colours and the tongue has a nike logo. Other than that, its the exact same shoe. I may get a few myself and paint them up, works out much cheaper.
Would only need some paint on the heel and swoosh and you have identical bruins to the red white ones.
