Product.... Nike is just innovating all the other legacy product makers, Rebook, Puma, and even Adidas. Especially in the soccer gear department, Nike is just outcompeting them.

Adidas, should have been first, since it is a European company, but they just slacked and their product line stagnated. They thought it was just a marketing problem, which it was not. Just changing their logo to something cooler, didn't make their products any better.

I was an Adidas fan, since they were the 'product of the west', of all the kids that were born under communism. They, and together with Puma made the best soccer shoes and gear. But over time, Nike started innovating hard, and releasing better engineered soccer shoes, and wear. (their Drifit Nikefit shirts are great).
