I've never bought a pair of Nike shoes before, never liked Nike even though I have to admit, some of their shoes look sick, and a lot of pros I like ride for the company. I don't buy Nike purely because of ethical reasons as stated by most in the thread, but at the same time, I've been guilty of buying CONS (owned by Nike) and a few pair of Adidas. I'm pretty much a hypocrite in this sense, I can't get over how well the few Cons and Adidas I've owned have skated.
Still, 70% of the shoes I buy have been skater owned, mostly Lakai, Etnies, Emerica and DC, they are just way cheaper. At the same time, I think most of these brands have been marketing themselves terribly, they don't fit the whole metropolitan skate vibe that seems to be popular nowadays. I think there's a reason why CONS and Adidas has such a grasp on me, their edits have been so on point and appealing, I don't see other shoe companies making any effort to appeal in the way they are, and that's a shame because the shoes can definitely compete in quality.
I think the people who worship Nike shoes are the type of people that are too scared to venture outside, and find other shoes that could work for them. I never ride the same shoe twice in a row, I like trying new things in the hopes of finding something new that I like, I could never skate 10 pairs of Janoski's in a row, that's way too boring.
