I cant walk down the street with my Nikes on!

I'm extremely upset at Nike SA, despite purchasing my Nike Machrunner sneaker last year from A Studio 88 Store. The shoe started to separate from the sole and plastic started to show. I contacted Nike SA as its over 6months so studio 88 can't assist. Only to be told that they can't assist me either as the shoe is over 6months old. The decision wasn't made by them taking the shoe for analysis or anything. They looked at the pictures I sent via email to make a decision. Nike is an international brand and according to their website it says if there's an issue with any of their apparel within two years of manufacture it can be replaced or a refund be done. But Nike SA refuses to assist me in anyway or take the shoe for analysis. We spend so much money purchasing name branded goods that only last just over a year. Cheap products being sold at expensive prices. Pathetic
