POOR TEKKIE QUALITY

I bough myself a pair of Niks Airmax 720 Mx-720 818 last year December a few days before my bday I had it on on my bday and and then a few times which I can count be hand of how many times I had it on. I pay R3000 for the tekkies. The tekkies I kept it in its original box the other day I discovered when I wanted to put it on that the bubble just when flat. I payed alot of money for that tekkie and had it on not evens 7 times yet.. and this happen. I am highly disappointed in Nike Seriously.
