Pop Goes the KD9s!!!

My son recently bought a pair of KD9s and after two weeks of playing DIII ball, the air bubble in the sneaker literally popped during a game, deflated and became concave in shape. In looking on line at Nike for the customer reviews for these bball sneakers, I found that there are many complaints by other customers who suffered the same problem of the air bubble popping and deflating. Nike only responded to these complaints by recommending that the customers take them back to the store. Nike remains silent on what corrective actions they have taken or will take to fix the problem! Only an injury will apparently get Nike to do something constructively!
