OP..
A lot of people are loyal to specific brands.
Take trucks for example. You have people who ONLY drive Fords. Then you have those who ONY drive Dodge. Then of course you have those who ONLY drive Chevy, not to mention those who ONLY drive Japanese Trucks like Toyota and Nissan. Same goes with cars. You have people who ONLY drive Japanese cars. Then you have those who ONLY drive American cars and you can't forget people who ONLY drive German cars.
Lastly, how many times you hear people say that they only use iphones or Apple products? Same with Samsung or Android phones?
As far as kicks are concerned, Nike is the king as far is popularity is concerned. Adidas, Puma, New Balance and other brands are also worldwide popular brands.
Me, I let it be known that I fukks with Diadora & Lotto tuff!!

I come from an eranor generation where you don't rock what everyone else rock. I am not a biter! But, every shoe brand has it's niche followers. The brands I like are no exception.
If you are a Nike head, the it is what it is! Whatever floats your boat!
