I have a pair of the newest nike CB's. I have no idea whats wrong with them but the heel portion of one of the shoes is "bubbled out". This is hard to explain in words. By bubbling out i mean the heel of the bottom of the shoe is popping out. Almost like the air sac was over inflated or something.This makes the bottom of the shoe oval instead of flat and may easily cause the twisting of an ankle or other injury. In all my years playing with nike shoes never seen this before. Question: can I mail them back to nike to get a new pair or would i mail them to TW in this case?
