Adidas — my shoe sole pasting is damaged

Sir, i have bought an adidas originals eqt shoe from flipkart. Its only 4months and my shoe's sole is leaving its paste. Should i go to the nearby adidas shop or you are going to solve my issue?
I have bought this expensive shoes cause i believed in your brand. Lots of my friends have bought your products so i also. But i am highly disappointed with your shoes. Now i think that i have wasted my money. If i have ever knew that this is going to happen i should have bought the fake product which look same and might be in usable condition more that this shoes.
