This is an article that I found to back up the point that Nike, although it is predominantly a sports brand; has conquered the fashion world. Their styles have waded their way as a necessity into everyones wardrobe. 

The quote I used from this article was: 

“Nike Air Max has gained the “must have” wardrobe item position once again after 25 years. Air Max comes from the 90s when the celebrities had been seen sporting them. Celebrities like singers Rita Ora and Lily Allen, Twilight actor Robert Pattison were seen wearing these cushioned trainers. Even President Obama is a proud owner of a pair Air Max.”
