I bought my son a pair of Nike airmax tennis shoes for 160.00. After only 4 months the bottom of the shoes have worn on the sides of the sole to the point that air has come out of the cushion. I am very upset that I spent that much money on a pair of shoes and they lasted no longer than this. He has a pair of Reebok zigzags that he has been wearing for 8 months and they were almost half the amount as the Nikes. I would like to think I just got a bad pair but at 160.00 a pair I cant afford to find out.
